ok firstly the jet needs to be bigger a standard jet is not going to provide enough fuel in the mixture to run right i would sayta least a 70 main jet .the bike will rev up to whatever the rev limiter allows it to providing its carburation is good and the air filter and exhaust are free flowing.i would put 5 gram rollers with that pipe too.just make sure you dont lose any top end as if you go too light it stops the rollers being able to put enough pressure on the belt to pull into the clutch pulley all the way.if you do lose top end with 5 gram rollers then put 3 of the old ones back in and arrange them so they are like a triangle.
