first time posting here but i swear ive researched old topics before posting hahah..... just bought my first shee and it needed top end build, had cylinders bored and honed and now its time to start modding. it had fmf phattys with power core 2 silencers, 260 mains and stock filter. i swapped filter for the uni dual stage foam and adapter. dropped a tooth on front spocket and waiting on chariot billet timing advance. im running 93 octance and klotz benol..... im in memphis,tn and im not sure of elevation but arent my mains a little small? most people here with similar mods have at least 300 mains in..just wondering? also i do aggresive trails and the occasional drags with friends.... i will be moving to ported cylinders and a 4mill long rod very soon, so more questions will arrise.
