Title: HD sportster engine update
Post by: Lakes on May 19, 2018, 06:51:01

Well one year back I bought a used Harley Sportster, with the plan to rebuild motor how I wanted.
Have just started

(https://preview.ibb.co/c1m5rT/IMG_2177.jpg) (https://ibb.co/bNBGy8)
Resizing cases in Bridgeport Mill, using micro bore

(https://preview.ibb.co/hHa9J8/IMG_2182.jpg) (https://ibb.co/gj0by8)
New barrels , fitted to resized cases. note, this is a pic of drive side of primary. where engine Sproket , triplex primary chain and clutch hub go. the drive side of flywheels on this model, use tappered timkin bearing, was the last year this was used. much stronger than the new model's. also that cave you see is where gear box goes. comes out via trap door. new models lost this and to get to gear box. it needs a full  engine & cases disassembly. so I wanted this model as was last year of these features.

(https://preview.ibb.co/kdxdBT/IMG_2145.jpg) (https://ibb.co/c3hpJ8)

I picked up these new heads came from a 2018 EFI, guy imported modified heads from USA. offered them at a good price. these heads are the best Harley have offered. they have smaller & higher ports, but slightly larger intake valves. they flow more air & higher velocity , than the older model heads my bike came with. I had to import a special intake manifold to fit a carb to these heads.
the new barrels came with JE forged Flat Top pistons. with the chamber the new heads have the compression is 11.5, higher than I want, I'll drop it to 10.5. as cam set I'm using with 10.5 should have 200 p.s.i cranking pressure.
I'll get the ports lightly ported & fit larger intake valves & bee hive valve springs to take 600. valve lift.
hope I did not bore you with detail's.
cheers

Pretty cool for a 70 y/o guy! Plus, looks like you worked out how to add pictures yourself!

I'm not  a bike person but it didn't BORE me (see what I did there).

I'm sure our Motorcycle members will really enjoy following your story as it unfolds. :victory:

Good job Lakes  :goodjob2: I love build projects :)

Are you dropping the compression for reliability? or you just don't want to use 98 RON :)

Hey thanks Dazz. I enjoyed finally meeting you & Trish!!

The next plan might shock you.

once I run it in on Dyno. I plan to enter an all Bike Drag race meeting up near Gladston, ride up ride home.
Good job Lakes  :goodjob2: I love build projects :)

Thanks Craig.
well I will have to use 98 RON with this build, but cam manufacturer told me the cams I'm going to use best at 10.5. they are relatively mild. but I believe . it's not the cam that determines how much HP you make but the Heads. also I want bulk torque. but it will make it harder to race, as this bike light & short wheelbase.
I'm having forks custom built to my & bikes weight & have Ohlins shocks.
bike will not be low like most Harleys as I like riding around corners too. will make it harder to drag race. but I'll be riding on street more than racing.
I would love some carbon wheels!!

Great stuff Lakes 👍
Not a Harley guy myself,  but I like things that have grunt. You'll have a truck load of torque available.
Have you thought of going to the "dark side" and using a car tyre on the rear, wider grip area / more traction. Is that equipment in the pics yours ?
Title: Re: HD sportster engine update
Post by: Lakes on May 30, 2018, 11:15:11
Hi Mick thanks, the mill is a friend of mine, Bridgeport  he has a really good set up, can cut high quality valve seats too. I will get him to do the heads. he has a flow bench. and a Dyno Jet 250i ( with load control ) chasis dyno. in a climate controlled sound proof room, with real time afr monitoring. more for mapping EFI. but helps jet carb close, some carbs a compromise. the one I have is good I can get it very close.
I would not use a car tyre as they are flat, I like riding in twists too. that's why I got this model Sportster it can lean ? I'll have to work out angle, but could knees down ( if you were good ) I like skinny tyres, as less drag so faster. on the street never use what you have. but at drag strip they spray traction compound, so normally wheel stands, what I'll have to control ( I do that with the clutch ) also getting a guy to do the forks & Ohlins shocks to the weight. the brakes won't be that good but ok. the engine braking would surprise you, a bit like a truck using exhaust brake. when you built to increase torque, it also increases engine braking.

Post by: Lakes on June 26, 2018, 01:41:08
few more pictures, I had the piston skirts dry lube coated, and about to do heads, the intake port looks good stock, will weld up exhaust port floor. also a few carb's I have, not sure what one I'll use. one is a 2 inch SU with improved float chamber.
the other one is an S&S super D that has a thunder jet ( gives it one more fuel curve up high so can use a smaller main jet, for sharper mid range throttle response )

Great progress lakes,
The coating is a nice touch along with recess in the pistons to avoid smacking the valves 😊👍.
S&S might be a bit more practical on the road.
 Either way, going to make some awesome induction noise when cracked open 😀😀👍

Work of art
Title: Re: HD sportster engine update
Post by: Lakes on July 21, 2018, 11:49:14
more work done, but still lot more left to do.


(https://preview.ibb.co/ms24UJ/IMG_2368.jpg) (https://ibb.co/ndLr9J)
 
chamber has been enlarged to get compression ratio to 10.5 to match the cam's


(https://preview.ibb.co/bYPXid/IMG_2367.jpg) (https://ibb.co/ekauwy)

this is exhaust port, had floor welded & D port as increases flow, I'm getting better flowing valves, the intakes will be larger and exhaust stock size.

will also get better quality bee hive valve springs and set to take 650 valve lift, but cams I'm using only open to 560, but I want valves springs to last a long time so as they won't be close to compressed they will last longer.


(https://preview.ibb.co/erOEwy/IMG_2366.jpg) (https://ibb.co/hprOpJ)

this is intake port the port looked good stock so just had it roughed up and now just need to finish matching the port to intake manifold.
after heads are set up , then motor will be mocked up to check all clearances. then pulled apart the re built properly.

I have forks & Ohlins shocks back from Shock Treatment , they set them up for the weights, these guys experts & do factory race bikes.

@Dazzler , don't know how much you know,  simply :
Basically Lakes is aligning the intake flow to allow faster amounts of mixture in . "More Power"
Valves bigger for increased flow. "More Power ".
Valve springs stronger enough to handle roughly 20% more valve lift than he's going to use .
"No Stress" - reliability increase.
Forks - front suspension units. Springs coils inside hyd tubes.
Rear shocks- rear suspension units. Spring coils over hyd tubes.

Its being built strong enough to be :
flogged all day, every day, for the next 20 years. :lol:  :goodjob:

@Lakes ,
Not going to get much traction is in 1st,  or 2nd !   :evil: :evil:

thank's Mick, the bee hive valve springs, are able to run at much lighter spring pressure, than the old multi straight valve springs , that used three coils one inside the other. the benefit of one bee hive spring ( shaped like a bee hive oval ) is can stabilise valves at high revs with a lot less seat pressure. so less wear on components. the idea on setting up for 650  valve lift is the spring can compress to 650, before spring bind, were as if had springs that could only allow 570 lift, the springs would be almost fully compressed at 560, so if valve springs compressing almost fully & also when motor turns off you will have a valve open. so that spring will be sitting almost fully compressed. were as having springs that can open 100 more before they are at the limit and fully compressed to spring bind. they will keep there tension for a lot longer. when your valve springs loose tension they lose control at high rev's and don't keep cam followers on the cam lobe. but the cams I'm going to use farly gentle on opening and closing.

My old 192 ran triple springs, low lift but long duration.  Quick open and quick closed.

My old 192 ran triple springs, low lift but long duration.  Quick open and quick closed.

I had a few hot Holden 6 packs Mick.

the cam's I'm using on the bike shorter duration medium high lift, I found with last Harley ( big twin Dyna Twin Cam ) doing mods to head and intake, got me to same speeds same ET at drags with milder cams, as I got with longer duration high lift. I was tuning on a Dyno & testing at Sydney Drags eastern creek.
was a small motor by Harley standards and I could ride it anywhere, I had it doing 11.2  @ 121 mph 1/4 mile with that trap speed it could have ran high 10 seconds, but I would have had to get 60 foot time down more ( higher rev out the hole ) with a lot of air under front tyre.
a guy I know with a sportster like mine same size motor as I'm building runs 10.2 @ 128mph and rides it to the track. but good rider.
but you can buy a new 1,000 , Yamaha, Suzuki , Kawasaki, or Honda . and if you can ride run high 9's @ 140mph straight from showroom floor. ha ha but riding the Harley totally different they pull hard from 2,000 with a power & Torque band like a hot V8.
the 1,000 gap multi run 6,000 up like a high turned 4 cyl

Back at it, my mate just sent me a few pictures of work he has done, this is on his Mira Centronic , cutting valve seats, have larger intake valves than stock but stock size exhaust valves, just higher performance than stock valves as have stroker retainers for higher rev's.

(https://preview.ibb.co/dxV9R8/IMG_2382.jpg) (https://ibb.co/ii0nDo)

here is a picture of intake port and new intake valve. if you look at earlier pic's you will see the valve guide end is flat and wide, then later you can see valve guides have been pressed out to make it easier to do the ports. not look at this picture, you see the valve guide is back inlace & the end has been machined round and tampered for improved flow. with mass production, can't expect this but say Holden special vet or Ford Performance would prep heads like this. or similar.


(https://preview.ibb.co/iUiM68/IMG_2381.jpg) (https://ibb.co/nhcQYo)

here is a pic of heads with the new performance valves & bee hive valve springs, the valve stems are the new 7mm as give improved flow. all new stock Harleys come with 7mm stems. but the old Harleys I think about 2003 & back had thicker valve stems.

Well a bit more work done to motor. when you modify a motor it's always a bit more work as have to check clearances and then , check you have correct compression ratio to work with rest of the set up.
I got larger intake valves but stock exhaust valves , just stronger more durable & more secure, retention ( the type of collars valve stems have & the coating valves have ).
also with the use of larger intake have to check valve to valve clearance @ TDC valve lift. that has all been checked now measuring combustion chamber volume ( C C ing chamber ) will also have to measure valve relief pockets that are machined into pistons , then work out & check we have 10.5: 1 comp ratio. when that is done, do an engine mock up to check all clearances when engine rotates. then pull apart. then assemble motor & gear box ( will back cut gears for quick shifting ).
should be up and running in around three weeks.

probably need to put a 4 cyl multi into a mill to do same ( if needed ). we did it as needed the piston to come up higher in the bore, to get comp right. some machine the head but you get better use of chamber bringing piston up higher in bore.

flywheels being pressed apart to remove rods, then pressed together & trued. then the pod ends, the pistons the piston pins, the rings and the clips that hold piston pins in. will all be weighed then the weight in grams will be worked out to give a balance factor of 52%, then what they call pop weights will be bolted in place of the rods & pistons. and the flywheels will then go onto a dynamic balancer it tells were to remove or add weigh ( don't expect this will need weight added ) then once it is balanced the pop weights are removed then rods & roller bearings replaced and the flywheels will be pressed back together then that press fitted crank pin will be welded in place to make it stronger and stop slip.

Hi Craig , my friend has a new set of Corillo Rods that fit, but the stock rods are pretty good I have not seen any break myself. & have never broken a rod on a Harley. but have seen Top Fuel Harleys do it & some 124inch s&s motors break them. I won't be reving high prob about 6.5 maximum . the motor would go well over, if I lt it.
the weak part of all Harley rods is the Female rod at the base.

Hey Dazz, I'll enjoy it more when I'm riding it. the way my friend set's up the gear box, I can shift that quick. it makes a big difference drag racing. he did gear box on my last Harley Big twin ( this is a sporty ) the last bike flew for a stock capacity street HD.
with this one just have to see. I'll post a pic of a sporty same style as this just longer swing arm. guy has similar mods to mine same barrels same stroke just barrels on his bored to the max ( I like to have room to resize after it needs a rebuild )

Yeah I wasn’t expecting them to break, usually pretty solid motors, was more thinking if you’re looking at performance you could reduce the rotational mass with some lightweight comp rods...give it that extra bit of pep😁

Hey Mick  good point, but he is drag racing, see how he has finger on clutch leaver, & both feet coming off ground together. you need to have both feet on ground to do a straight pass, one foot on peg and you weave to one side. if Bike goes up too high he will control it with the clutch. it will come down smoothly under full power. it has 6 inch longer than stock swingarm. makes them easier to to race straight line but I don't like the look. and slower in corners.

Seen some huge extensions done on Hyabussa's etc, in the end they just make doing  burnouts at  speed easier.

I used to race against, guy's with extended swingarm Busha's, most had turbo's. helped give them more confidence to, try to get 60 ft time down in quarter mile. as you have to go very hard off the line to do a quick 60ft , if you go off easy then give it more you finish up runing mid 11's ( on a haybusha. but I also knew riders that could run a 9.7 on a stock hayusha off showroom floor. but very good riders. problem is it is not as easy as just putting a very long swingarm on. they have to spend a lot of time setting the bike up. can have a traction problem moving the rear wheel back too far. but another problem is if they use a slick tyre or a Shinko hook up, they can't just drop the clutch at high rev. I raced a guy with a very long swingarm and a flat car type slick. was a jap bike. he did that at the track with the track race prepared ( very sticky ) and when the light dropped in his lane he stood the bike straight up on rear wheel. because of long swinarm, the rider was very high up in the air, he backed off very quick and bike dropped with a jolt. :Shocked: :eek: think he messed his pants.

I used to race against, guy's with extended swingarm Busha's, most had turbo's. helped give them more confidence to, try to get 60 ft time down in quarter mile. as you have to go very hard off the line to do a quick 60ft , if you go off easy then give it more you finish up runing mid 11's ( on a haybusha. but I also knew riders that could run a 9.7 on a stock hayusha off showroom floor. but very good riders. problem is it is not as easy as just putting a very long swingarm on. they have to spend a lot of time setting the bike up. can have a traction problem moving the rear wheel back too far. but another problem is if they use a slick tyre or a Shinko hook up, they can't just drop the clutch at high rev. I raced a guy with a very long swingarm and a flat car type slick. was a jap bike. he did that at the track with the track race prepared ( very sticky ) and when the light dropped in his lane he stood the bike straight up on rear wheel. because of long swinarm, the rider was very high up in the air, he backed off very quick and bike dropped with a jolt. :Shocked: :eek: think he messed his pants.
And probably cracked a nut   :lol:

also forgot to show flywheels finished, they found roller bearings & crank pin to be like new, but big end of rods like an egg, so resized & got rods perfect, balanced trued & welded crank pin. the guy who did it is from Sweden , ( lives here in Australia now ) he has worked in aircraft industry & does good work. he has also lived & worked in USA. I'm happy with the job he did.

hi again Dazz, my friend just told me motor is in the bike now, he still has to mount pipes fit the new Ohlins shocks put tank on, then when he starts it he will have to do the heat cycles ( you start & stop & start a few times , letting motor cool between the starts & stops ) after that he will take it for short rides or might put on his Dyno to run it in a bit. I hate running them in myself.hate riding in Sydney when motor new, I'll probably leave very early morning, when I finally ride it home.

Hi Craig , I'm not into solo seats to me these late bikes with them just trying to imitate the. early big twins 1980 back that had a down tube as part of frame and a steel rod that was almost like a fork tube. it had its own spring inside. that you could adjust spring pressure for different weight riders they had a welded to frame braket that was between the duel fat bob tanks. the back two holes mounted an arm that was a pivot support for front of suspension seat then next two holes up were the rear fat bob fuel tanks rear mount brakets , these where the original style tanks & solo seat they used right back to 1930's. but 1981 they lost the machined inside down tube on frame and later the fuel tank became one piece with one dummy fuel cap & a band cover in middle to try to replicate the old duel fuel tanks. I've always looked at them as imitation. also the sporty's with the solo seat, the cheapest models the one with this seat was XLH 1200 this year, & I just want it to look stock original as this bike never been damaged & all original paint. I'm more a motor man.
In and fired up, beauty.

no worries Craig, a lot of people like that style, another thing is my seat seems to give support from me sliding back under exelleration. when I go to the track the first 60 foot can be hard on that.

well I have her home!!
And now have 1,000k up very careful run in as barrels are Nodular Iron so does not expand and holds it's round, the piston's are JE forged. so I have to wear the pistons in to the bore ( slowly ) been keeping rev's below 3,000. she is a bit like a diesel as pulls strong from 2,000 in top gear ( 5th ).
today I did a 50 k pushing ride on dirt track in hill's out of Bodalla, then rushed home get the bike out fill it at the BP with 98. then off south went to Eden road to the big Wharf to find a good feed of fish. as I get my helmet off and my first bionic ear on I hear this loud yelling, look around and some guy all excited wearing a Harley Davidson cap, is yelling out " nice Sporty mate!! " so I walk over to him as he is standing out side a few restaurants , he say's what year is it? I tell him and he used to own one, we walk over and he is saying oh I love the pipes, I love the air cleaner, Oh you got good shock as the rear of bike is high, I said yeh I like taking corners quick. he said most people make them really low so good to see something different. then tells me he is from Central Coast, him & wife going down Melbourne to pick up a new Harley Trike & ride around Tassie. I said sounds great, also I just got given a new Harley big twin EFI that has the 8 valve motor to take for a long ride. my friend in Sydney had just bought it new, it went good had a huge motor and ride by wire like the i30's, this guy said his new trike is a sport glide that has one of those motors think he said 114 cubic inch.
then I say where is the best place to get a good feed of fish, he say's anywhere here as fishing trawlers just over the road.
so finished up with a nice seafood dish & salad .
I was thinking I should contact MickD but was getting late afternoon and needed to get home. on trip home bike felt a lot more responsive but did not go past 3,500. I'll give it another 1,000k & drop oil. then ride up Sydney for fine tuning as runing it slightly richer & have retired timing. checked cranking pressure and its 220 pound so on high side but it really pulls strong.

Hey Mick understand what it's like!! But you would have heaps more than I had to move!!
I always like the run down the coast to Eden Wharf, I like Tathra wharf too, but getting a feed on tathra wharf, makes you feel like u just got mugged!! they charge like a wounded Bull!! LOL but love that Massive old Wharf and how is has been preserved .
If Dazz meet's this couple ......... the guy was so happy and prancing around like he had springs under his feet!! wife  looked like still recovering, sat down beside water never moved. good to see someone happy!! Dazz would get on with them , he is a top chap!! weather would be great this time of year too!!
