The longest stroke i can find is the 996 66mm.......the std 999 (998cc) is 63.5..........of course you could make a crank but, the 996 is favourable......and realistic and relatively cheap........... The trouble is extracting the 170 bhp from the 749 bore makes it highly tuned and unreliable........in any case if you have a 749r why not fit 999r bore and a 996 stroke.................kind of wouldnt be a baby r any more though! |
