I have a 00 sxr 600 chassis with 700 stock clutching 8ch weights stock sec. Picked up a 51/43 helix and green spring. Should I play with primary or just put in the helix and spring. Still has stock 600 gears. Gonna put in reed spacers.
go to the tech pages and find Turk's clutch setups and use them. drop one tooth on the top gear and do the head gasket/airbox/silencer mods and you will love it.
