Anybody done any work on these engines?
I'm after a bit more at the top end, i.e. after 8000 rpm where the power flattens out. Bike fitted with 50mm exhaust system and over bell mouth air filters. Next job is adjustable cam pulleys to fiddle with the cam timing, but I would prefer not to lose too much mid range. Any suggestions (apart from buy a GSXR 1000

) gratefully received.
