Hello all, right my NRG Power Dd has gradually been loosing power over the last 3 months, it had a 2nd hand mallossi 70cc kit on it and I used to get a clock speed of about 55-60 and now it's down to 35mph, so I through I'll change the 70cc kit with the exactly the same kit but still does 35, I know it has a upgraded veriator and clutch spring but not sure on the weight of the rollers, could the rollers be effecting the power and what ones would you recommend to be replaced, and are there any other suggestions Many thanks Ricky
6 gram rollers. 72 jet (with pipe/70's) standard torsion spring, I'd check your gear box out too, you could probably do with a new belt too.
you want to invest in a laser pipe for that mallosi kit as thay work really well togeather and if you have the wongaa invest in a new crank as if that 70 kit is a mid/race kit it might eat the crank just be carefull
