The 929/954 head thing ....ahah ...i seriously don't think that it is posisble
different width ..different size and all..bolt locations on the block doesn't make it possible to me :p
I just started my 919 with 900RR 98 cams ( fitted a lathed cam pulse sensor on it )
..stock bottom ..shaved head 0.030" and ported/matched TB/Head
and to my surprise it ran fine..except for the fire that caught in my tail after 30-40 seconds of run ( but that's another problem .. )
most of 900RR head parts and pistons will fit..but the difference in pistons dome height makes it not worth it compared to aftermarket pistons
can't wait to get DA exhaust on ( bented :p 954 header + all custom rest )
so about the streetfighter... i think that BigASS'z bike is an awsome work of art!
and i am 100% sure that this bike was a real nice project to work on
( unlike mine wich was only @#$@!$# since start :p )
so neway here is a quick peak of what i'tll look like
( if it doesnt' burn compeltly next time i start it up :p )
