Did you put put rollers in right? You got to bend/move the spring clip and put under the clip,
Are spring clips weak or rusted?
Did you shim your thrust plate?
If everything was done correctly sounds like you have the perfect set up for a fast kitted bike! when you want clutches and everything to slip,
Thats how I tune my clutches/za50 engines, I find clutches and parts that slip real good and put them in a engine that I’m gonna put a high-powered kit on it,
For slow stock you want to engage at a really low RPM,but for non-stock kitted you need a lot of slip and blip shift
