That was a very nice weld job on the big bore stroker, I know a fella who still has a 3.50 X 5.00 iron head = 96". That used to be the biggest you could commonly make an iron head, it's name is "Doctor Death" man that thing is hard to get started. It was built by Zack Reynolds ( Reynolds tobbacco ) That thing had great bottom end and really hauled ass from about 2500- 5000rpm, it started to run out of air after that, was quite a bike for it's time. It would outrun Z-1's and Honda 750's, pretty good for 1974.............Steve

Monte that sounds like a challenge
Lowry, I could have gone up to 103" on my motor but it would have needed rollers and a car to start it.

I know it would, how much cranking pressure does your beast have? I think the best running 103" iron head I ever saw belonged to a XL pro stock racer named Sonny Mikalowski, before the Harley race team V-Rods came on the scene in the NHRA, Mikalowski was the last Harley to be in the finals @ the Gator Nationals (1983) with the ole 103" iron head, he lost to some kind of kawasaki. That was the beginning of a long draught. Your bike is bad to the bone, I like that stociek trap door, now that's a blast from the past....Steve

well......thanx for all the info guys......

Mick.......ive learned alot from reading your resonses on many many threads......i respect the way you keep your personal opinions more to yourself and put out the info that you have pertinent to the request of the quesioner......thanx for that.....

11B40.......i don't know what trama you speek of but....the goal of my project doesn't exclude replowing old ground........in fact thats the easiest dirt to till.......I was offended however that you would assume that i could confuse my ride for a jap........i dont even think that is posible for an idiot to do........

thanx mont, apreciate your info.........i have the utmost respect for stroker but, (i'm not afraid of alot of work and lon process), that's not the project i'm goin for.......you'ld never see me on an evo,.....i'm a motorhead not a dentist......hee hee.....(no offence intended)....and, inch for inch, i'd like to see the stroker that could walk away from an rpm big bore...

thanx, buck I, ...nice to meat you

hi nofat,.....couldn't seem to find those cases......thanx

hey, 66ch........yeah after more thought and gathering of info, i don't think studing the cases and rubber gaskets to compensate for expansion would be the way to go for me......thanx for your support on bore vs stroke.......thats some good information that i will retain for further decision.........

kool pics, FIRE37.......i agree with steve, nice welding........is it soup yet?........wow 3 5/8 X 4.5.....is that a double reduction starter?........he he he ........nice work.....thanx for your help

thank you everybody......great start........keep the rubber under......later

Then there's the Sputhe steamroller, all bore and the quickest and fastest bike Cycle world ever tested around 1980 or so. There's a thread on somewhere in here.

Yeah, that was me the post was in the "frame mounted sportster talk" I know Allen Sputhe, he made some really cool and innovative stuff for XL's back in the eighties. Still makes harley parts but not much for XL's the big twin carb heads and barrels are a part of history.

Steve ,
That is a beautiful machine, I still have magazines of years back when Sputhe created these awesome top ends, wish they were available today, this bike is the perfect Cafe' type Sportster, it looks raw and not covered up with plastic.. nice...
