    Hello everyone, i have a standard mbk nitro with purple thrust spring, original clutch springs, original variator, original clutch, 6gr rollers and malossi 16x8x751 belt also i added two flat washers so it won't sink in the clutch, the acceleration is good but the top speed isn't because the belt won't reach the top of the variator, so what's the solution?
