help on ballpark getting

[pa308]

hey guys i was wondering if u could help me out on getting my jetting close or tell me if i am close. Here aremy mods- fresh topend wiseco pro lites .080 over, shaved stock head .020, cleaned up reed cage castings, boyesan reed valves, boost bottle, air box drilled with no lid and prodesign filter, fmf fatties and stock carbs. Right now im jetted at 260 mains stock pilot, and needle on 2 clip from top. The bike runs good except i had a bogging down low but i set the air scews half turn out and it cleared it up better. The topend just doesnt seem to be a lot but i think it might be the sprockets. i have 13 40 i believe. what shouldmy topend be with that sprocketing. my elevation is probaly no more than 300 to 500 above sealevel and i run 93 octane mixed at 36 to1. thanks a lot everyone

Put your gearing at stock, 14/41 or 14/42. You're not gonna have a lot of top end with that gearing.

 

Put 300 mains in...to start. Follow this to dial them in. 260 mains around here is too lean with no lid, we average 280 or 290...and probably up one to two sizes from there if they ride in the snow/ice/winter time...
