hmm juz wanted to ask u all how do i modify my nsr150 to clear my meter. hmm wht do i need to change to make my nsr150 become damn fast!!!! hehe

If you use the search key someone has already asked this just recently, but i recall that its expensive to make it move QUICKER, try TYGA for some bits.

The NSR150SP has reasonable piston, cylinders & heads, but that's about all! The carb is too small, the intake is restrictive, the flywheel is heavy, the balance shaft is not very well balanced and the stock exhaust is heavy and passes less gass than Andy after a night on the razz. You can get up to about 29hp with a pipe. Maybe 30 with a carb as well, but anything after that requires that you go internal and start cutting.

hmm wht brand of carb is gd??? i changed my exhuast systerm already to hrc chamber, racing cdi and K & N air filter. wht should i change now??? lik racing block,piston....etc?
