That sounds incredibly smooth, even mellow in the video.
A bit surprising given the cam specs.
Be good to get her run in and see how she performs .

Here's a quick vid of the 120 I took when I was playing with jetting.

Thanks speedster!!
that is a beautiful bike you got!! those 120" s fly.!!

The Twin Tech cone ignition I have has multiple spark setting seems to clean up idle, the Woods CV is a SE CV44 that Bob Woods bored out Venturi to 43.5, he also sets it up a lot different to stock seemed to always idle pretty good. but the 560 Impact Hammer cams, Aron from Hammer told me to run 10.5 comp with these cams as they need it. so Cow worked out what size chamber needed to be @ what deck hight, that's why in the pic's you see base of barrels being machined off, to bring pistons up to right hight to match chamber to get 10.5. should be 200 pound cranking when motor warm.
but will just have to wait till get bike on dyno to see if carb can be set at right afr at high rev under load. have had the carb a while but have never checked that, this time I want to.

well, road her home, takes a while to run the Axtell jug's in ( nodular iron ) so have to wear piston's into the barrels .
But no worries have been limiting rev to 3,000 , Cow set rev limit at 4,500 till I get enough k's up. ( should not be too long )
It is a beautiful motor to ride especially with the Bobby Wood 43.5 Rebel CV, cow tuned it and plugs looked as clean as EFI it got 3L per 100K running in. then he fattened it up slightly for me to run in as had a 300 plus K ride home. using 4L per 100K home.
when it was stock 1200 open chamber CV40 carb adjustable twin Tech ignition stock headers SE slip on's stock cam's. I needed to keep rev's 3,500 up to keep motor happy ( stock gearing ).
Now stock gearing , 88" 1450cc Hammer Impact 560 cams , S&S premium lifters, Late sporty EFI heads Larger intake valves stock size exhaust valves. L A Cycles done the heads, Flywheels balanced and welded. Tappered end duels, no cross over, Wood's 43.5 Rebel carb. stock clutch unknown if ever had any changes to stock, as was a lady owner, but just left it as is. now it pull's smooth and happy 2,000 roll throttle and it shoots to 3,000 no hesitation almost electric like. the gear box is magic Cow a master at setting up a race gear box!! ( but this bike so nice to ride, I'm not thrashing it at drag strip!! I'll take it down the quarter but not flogging it ) also while in Sydney road to Shock Treatment as they set up forks and shocks, they checked and set everything with me sitting on bike.
so have to get about 1,600 k up before it's ready for a rev out and fine tune.
judging by how strong it feels at low rev, when I pass 3,000 I'm going to have to hang on.
also was lucky enough to get a ride on a new Milwaukee 8 Lowrider ( stock as a rock , sounded like wind in the tree's or a dish washer ) it went good felt heavy. Cow has some mod's & will do a custom map on his DJ 250 I , so hope to get a ride after that.

Great and interesting read, I particularly like the finished product, a beaut looking stock sporty, a sporty put back where the sportster belong, on top of the Harley hot rod tree, back in '68? the Sportster was King of the street, It's reputation today is an insult to the Sportsters original design brief and legacy, ok i'll step down off my soapbox now, here's my question,
What i'm interesting in is the 2 images at the very start of this post, I can see the mill is dressing the cylinder surfaces, but have these cases been bored yet ?, I can't tell, I would have imagined for such large cylinders that the hole in the crankcases would have been much closer to the threads, I could be wrong, I usually am,

Thanks liberator, that pic at start is actually a micro bore fitted to a Bridgeport mill, and in the pic that is the cases being resized to take the Axtell 88" iron barrels, these barrels have plenty of meat and can be bored out to 90". but I like having the extra meat to keep bore stable.
it now has 1,000k up and I've kept rev's below 3,000 but took it to 3,500 an hour ago ( on open road no traffic ) it is really pulling strong & I am surprised just how smooth the motor is. As this is a rigid mounted motor to frame. nShock Treatment at Wallacia ( just out of Sydney ) did a fantastic job on those old Ohlins shocks, the worked on the damping. and they did the stock forks with Race Tech Springs & gold valving. the set up is rock hard, but when I give it some throttle & go through some tight twists it just carves them up with ease. the strong torque of the motor pulls it through the corners hard. I have not yet felt and steering shake so for now won't use a damper & don't think it will need one. but will find out once run in and fine tuned then hit 6,000rev see what happens.but I'm not a fantastic rider, still riding this to 3,500 pulling like a train till I back off, I feel like Val Rossi.
Also as far as I know the clutch is stock but the diaphragm spring feels heavier than a stock one, for now it's holding up ok, if spring plate starts to go and I feel it going, I'll then get a real clutch, probably a Bandit machine works as they are about the best & I have owned one in the past, can also set them up light & guy that makes them knows his stuff and can advise on a custom set up for a bike like this.

Well thing's take time, I have ridden the bike over 3,000km now, still with 4,500 rev limited. So have not yet got to open her right up , as another reason is still has stock clutch with the spring plate.
As I might have said before the forks ( stock 39mm ) were rebuild with race tech springs & other goodies by shock treatment out of Sydney ( stock length 03 XLH1200 ) Shock treatment did my old Ohlins Shock's worked on the damping set them up to my weight and bikes weight. they are 15" long ( stock shocks on this bike 13.5" ) now set at 14.5", but can adjust spring and they go out to 15". but at 14.5" now feels great really firm ride, can lean it right over nothing scrapes.
As I said have only gone to 4,500 and not giving it wide open, but it's so smooth could not believe it's a rigid mounted motor. I can look in the mirrors. bike pulls smooth in 5th 2,000 rev , has the stock 1200 gearing and stock belt drive. riding at 110kmh it's about just a tad over 3,000rev in 5th, stock gearing with 1200 as came stock it felt tall as needed to down shift to overtake quick if at 100kph in 5th had to go down a gear for a quick over take move. now 100kph in 5th just a bit of throtle she blasts past. this is all with run in tune ( jetted bit richer low mid jetting, timing retarded ) I been loving it using just under 5L (4.9-4.8L per 100K ) now ready to fit a SE extra plate clutch, will just leave stock pressure plate. as I hate heavy pull clutch's!! so the clutch upgrade very soon and a tune, then the action start's!!
Even though I'm an old bugger I'm still excited to take her down Quarter Mile & think I'll do a few laps on a race track see how I go there. but with the drag strip, you can't say or even guess what you will do, and that long black Dyno never lies!! But if you see a Slow ET & a very fast trap speed ..... you just look at the 60ft time, if that is slow ... just means as the bike has a fast trap speed, you have a quick bike that makes HP but a rider that's got a weak heart!! a bike like this if you drop the clutch on the line with high rev's on a drag strip that has some track preparation, so your boot's are sticking to the ground. the gas tank will come up & hit you in the chin!!
so I'll probably just go off the line from idle, but give it a fist full & hope I don't miss a shift & keep my head down and keep her wide open through speed traps. see what we get from a little old sporty, with a real old bugger on it.
but so far I'm in love!!
cheers

Well here is a pic of the spring plate, this one is 15 years old. when I got bike it was owned by a lady, bike had 22k km on it that was two years back. now has 38+k km & 3.5k with 88" motor. I've never been hard on my bikes even when I drag race. I don't show off I just do that to see what time and speed the bike can do.

here is the SE steels & pressure plate, I chose to use the new plates & new steels + the extra plate, but stick with the stock pressure plate, as I like a light clutch pull. so far so good no clutch slip I can notice. about all you notice removing the spring plate is no slip or give at all in first gear low speed, so every touch on the throttle is a quick jump in response. ( nothing really. with the extra plate u now have more surface area so can take a bit more torque than stock clutch. if I find it slips too much I'll just add that heavier pressure plate. but nothing wrong with clutch slip, it takes shock off the gear box and drive system. also makes it less agressive, so easier to get hook up at the track & off the lights.

here is the new SE clutch plates, they appear stock like but just use a different friction material, been soaked in primary oil.

here is a pick inside the primary, this is 15 years old note how clean and new looking, even the adjuster boot like new.

here is clutch & primary drive all as new, the blue patch on pressure plate indicates stock pressure plate. so I have a light clutch pull. probably won't find out if clutch slips till I take it to the drags. but just because your clutch slips , does not mean you would do a slower time, I found out long ago I was quicker with a slipping clutch.

Well I also replaced the battery , the battery it came to me with, never seen one before but the Lady said it had been in the bike three years, it was AGMtype but not genuine HD. well for the two years ( almost one year plus nine months ) I've owned it performed ok. it fired up the stock 1200 easy. then the motor grows & the comp goes up & cranking pressure goes up. well when cold it started weakly to turn motor over to start, once warm it was ok. so I thought good idea to get new battery. Cow had a new SSB battery in the box, checked and my battery in Sporty had a 270CCA battery, the SSB battery had 450 CCA. so got Cow to fit it as putting a battery in a Sporty a bugger of a job!! the difference was night & day, new battery spun the motor easy, quick push of button & bursts into life. I road the bike 350km rev limiter has been moved up from 4.5k rev to 7k rev but the normal ride I don't think I went over 5k did not need too. & off the lights its electric!!
Also note no jet changes needed carb as it was out the box ( ages ago ) I have ran very low 11's on a street Twin Cam Dyna 88" , that was an every day rider, with this carb. I have ridden a lot of miles with this carb over the years. will be interesting for me personally to see what I can do quarter mile in on this Sporty, from the feel of the bike, it is easy to go off the lights quick, & so as that's how I drag race, just like going off the lights to clear the traffic. I'm looking forward to going to the track, but no idea what I'll run just have to wait and see what long black Dyno has to say.

Very true!! Just showing they can last, important thing to note here is, a lady owned bike from new & road normally. Also as it's the 03 they had different heads open chamber & different ports. the new heads might not show a huge difference in posted Dyno Number's. what most posted Dyno numbers don't show but is very important, to how the motor performs on the street, is they don't show the time in second's, under full load, it takes to make HP & TQ.
if we saw a Dyno print out or screen shot with the power & torque in seconds, I would expect the late EFI motor that has had a full custom tune by someone that knows how to tune. I think we would see the late heads producing HP & TQ in a shorter length of time than the old open chamber carb. so with that in mind, the spring plate under a lot more load. I also own a M2 Buell Cyclone that has 100k km and spring plate was showing sign's of coming apart, put energy one clutch in & I have never liked that clutch, from the time I first road the bike with it in. but I like this SE 9 plate with the stock spring ( so far ). Buell a total different animal!!

well going great, I made a battery change, as the stock battery was 5 years old and the 88 cubic inch motor it was sounding like battery would die , it could barely crank it over when cold and. not much better warm. I checked the stock CCA & it's 270. I got a SSB that has 450 CCA, all of a sudden it spins & starts quick. love it.
Have not had it on Dyno yet & have only had a chance to rev it to 5,500 ( pull's hard ) also as I might have said , off lights , don't even need to rev, just drop clutch from idle and it jumps forward quick. this is a plus for me when I get to the track as will help me do a quick 60ft ( I hope!! ) I can't wait to take it to Sydney Drags one bike night to get a few pass's & find out if the clutch holds ok. also I got three mates with new M8's. that need to also get them to the track.
anyone interested in having a go on bike night, would be good to see a lot of HD's there!! It is just like racing off the traffic lights but it's legal!! you don't need anything the bike does not come stock with.

Well nearly nine. Months on, I'll have to check speedo but have over 10k up ride it every week. It goes hard & has stock 1200 belt drive gearing, pulls 5th gear 80 k up strong. Still not tunned or on dyno yet.
But will have it tunned soon it's still in run in tune.
Also I'm itching to take it to the track, just to see what time & trap speed I can do. I'll just ride normal but I can shift this really quick & clutchless. I might be a bit of a skirt out the hole as she is savage off the line & off idle, so ifi held revs up she would be a hand full till I get feel of it.
Can't wait. Plus surprises e how's smooth nothing comes loose or has cracked.
