looking for some input guys. heres my setup,41 fcr,stock airbox(no lid) with clamp on filter,wiseco 11:1 , hotcams stage 1 raptorcam in a cleaned up head,dynatek cdi and a newly installed ron woods pipe with a supertrapp.Im running 16 gram overdrive weights in a modified sheeve similiar to a hot rod and stock secondary spring. should i go with lighter weights and different secondary spring with the pipe? with the stock exhaust and stock clutching it pulls pretty good.installed the pipe and it doesnt feel that great yet, i still need to fine tune the carb but i dont feel its that far off on being correctly jetted. maybe im wrong. i do have a A/F meter that i hopefully can get on this week and find ou t for sure. Am i going to feel significant gains with this exhaust or am i dreaming ?
