If I can;t run a 16/41 then something is wrong. Blue Duece is running a 17/40 and that is alot higher geared than mine and he says that his is very very fast ans he is running it on an MX track. I am suppose to have around 80+hp and I know that I dont, something here is wrong. I can;t run a 16/41, that is just way to low geared I am shifting my ass off. I was running a 15/39 in the sand and it ran great other than the low end, there is no powerband untill I get up there in the RPMs. I will take my carbs apart and look at it and see what the jets are and post a message.
Oh and I do let it rev high before I shift also.
