I tell you guys what,i'm not into all the oil leaking,overheating madness trying to tame a tiger on the street.I built a 85 1100LTD a handful of years ago and I think Gast put a 1262 kit in the motor and that thing was badass fast for the street.1262 kit sound correct in a J block ? Maybe i'll just do another on of those for my old 78 .That piston kit,some head work and a set of radial slide carbs really woke that 1100 up.If that don't make me smile i'll bolt a hairdryer on board and boost it :evil: :woohoo: :laugh: :evil: :whistle:

I was thinking the same thing about a Busa. For 5 grand out where I live you can find one with a pipe & Dynojet Commander on it to race and keep the old KZ to ride. Im old and my back is good for about 5 miles on one of the new rockets but you cant build a good KZ type motor for what you can buy a potential 8 second Busa for. I fully understand not wanting a newer bike though. I have a 95 Fatboy with an S&S 124 in it that makes no financial sense at all but its easy on my back and I only have to mess with other Harleys

Nice, but where with a turbo do you need a full exhaust for? None of the bikes that have turbos have I ever seen with a full exhaust. Nice bike though. I have always been a fan of that particular color scheme.

I know there was a couple people running them on the street. You should be ok with it not overheating unless your running higher compression. I would stay with a lower compression around 9 to 1.

No full exhaust is really needed :blink: ...... it's called a sleeper :woohoo: .....I prefer it that way ...no one has a clue as to what hit em :huh: needless to say not all turbos have dump pipes, :dry: free flowing 3" inch I.D. stainless pipe from the turbo back to the can. can has nothing inside :lol: .....It's a HMF big bird turbo exhaust, mcxpress exclusive......looks stock till you look in the fairing slits and spot the intercooler..... also the air filter is not poking out the side no dump pipes for me on the hayabusa :cheer:

I agree Les...if only there was a way to hide one on a KZ although I have seen one where the turbo isunder seat or the tail...can't remember...I'll try to find the pic of the bike and post it...He has the panels behind carbs to hide things I know...



On the 1260, not sure what the compression is...I think its 10.5-1 but it has a J head so it may be lower or there might be J type pistons in there...won't know till I can get in there to find out....but was curious if they ran hot or not and was concerned with the thin cylinder liners after that big a bore....motor is in bike I bought but wither the trans or clutch is messed up cause I can't get it to shift without major effort so I guess it will be a winter project unless I can fit it in sometime to pull the pan.

With a j model head you will loose around two points of compression
