link didn't work.. there is only one front motor mount bolt.. which is a m10x1.25
Are you talking about the M8x1.25 bolts that attach the mounts to the frame? or the bolt that mounts the motor to the chassis?
I've ran my bikes with the same jetting from 40-100. They get a bit hard to start when the temps get cold.. other then that.. just a turn of the power jet.
