hi every 1 just built myself a zip with nrg mc3 engine runner rear shock and front forks and nrg wheels its a 50 at the moment but looking a 70 it wondering what the best kit was for reliability and performance i put a runner 125 carb on it with a 104 jet and a k and n filter an a race exhaust some mallossi rollers doin about 55 60 but need to go faster. any advice? im living near skegness any meets nearby? cheers tom. :grin:
erm most bore kits are reliable as long as your setup is right , and i know the fealing mate need more speed! should think about a performance crankshaft to go with the new bore
104 jet hock: the polini or malossi sport 70 kits are very reliable, but give a worthwhile increase in performance... welcome to the forum btw
