I'm hoping that some of you guys experienced this so you can help me out.
A friend bought a 57mm vixion kit months ago. His block already reaches more than 2000km. Now the problem is he can hardly hit 130kph, which he easily does using his stock bore.
His Mc runs fast up to 120kph then stalled at 125 for about 10 seconds then slowly climbing up to 130kph.
He uses REXTOR cdi, CMS cam, VIXION v-spring, 28mm keihin.
We tried 14-42 sprocket combi, 3rd gear 130kph but when you shift to 4th gear it rolls back to 125kph.
The best sprocket combi we tried so far is 14-44 but still not satisfactory. It can hardly hit 130kph.
What might be the problem?
Tappet setting is good, carb setting is good.
