I'm having problems with the speed its very slow,especially on uphill it does 30 to 35 on straights which isn't too bad but it looses power.and on uphill it drops to15.what wrong with it,I have put a q-tre race pipe on it.new piston and head.do I need to change my jets in carb or anything?.also would a70cc malossi head do anything for me
Yes you need to re-jet for the pipe also the rollers may need changing for lighter weight, as for the jet size you need to check what you already have and rollers need to be whatever feels right without bogging or over reving on acceleration..
