    Probably right around 120-130 psi. What do you have on it right now?

    Depends on the gearing and clutching, they are quick sleds if they are set up right.

    do you need to jet it or anything if there is an aftermarket silencer on it?

    probably just below 100. it all depends on too many factors, you will have to ride it too find out. then clutch work first if your not happy.
