ok i have to admit im a tinkerer and enjoy hiding in my shed filled with engeering machinary and i dont seem to be able to stop myself from trying to make my bike go faster n better, so now that ive said that my next brain storming idea was to put over size valves in the head to creat more flow.
dont know wot my options are with this, so asking anyone out there have they done it or do they know anything about it, good or bad?
current engine mods are-
T4 header + pipe
air filter + air box
carb mods, needal, ac pump +bowl+leak jet , jets 180-190,
power now
stage 3 hot cam
port/ polish head + extra valve angles+ planned 5 thou
removed base gasket
jd 2 stage ignision
slip clutch
going to bore out carb as well 2-3mm.
any thoughts?
