Ok, I have a 1997 RM125, the bike runs great and pulls with PLENTY of power, my jug has been freshly replated by millineum technologies, and it has a new top end in it. A r304 shorty and a stock expansion chamber, 50T rear sprocket and stock tooth front sprocket. My question is what can i do to pull more umph out of it. I've been looking at vforce 3 reeds, aftermarket expansion chambers like works gold series, platinum series, etc etc. but will these really help me that much? and i race tight indoor tracks and some outdoor tracks. i know my rear sprocket is too small im going to either a 52 or a 54 tooth in the back and im not sure about the front. But i know the V Force 3 reed setups are expensive, but are they really worth it? Thanks for the input guys.
