i am looking to install a 70cc kit on my runner sp. i read that the due plus is a really solid kit and i am between that and the stage6 streetrace kit. i am looking for reliability and power. thanks in advance
sorry have no experiance with the due plus cylinder... but I do rate the stage 6 street race. I fitted one some years ago to a lads runner, and i was quite impressed with the quality and performance for the money.
i have read some good feedback about the stage6 streetrace cylinder. i will be probably installing that one. my top speed is 101km/h on a downhill type road. on a straight it does 95. it is already pretty good for my setup: rms reinforced crankshaft standard 50cc cylinder with a prox piston polini speed control variator 5.3g rollers malossi flip homologated exhaust malossi belt malossi clutch springs modded air box malossi white contra spring. a lot will change obviously with the new cylinder. i will keep you posted
