what if like my bike currently is upgrade to UMA 65mm block with 34mm carburetor. should I need manual clutch or auto racing UMA clutch ?Lets think logicly guys ; by install manual clutch our engine gonna be heavy than stock...so topspeed is drop but better acceleration...
But...if the 4men got the spot to maximise power our engine then it gonna make us smile...Ngeh ngeh ngeh....in otherwords "BETTER PEFORMANCE ACHIEVE"
