Hi all, Just finally got my rollers right in my speedfight and found that I'm literally maxing my polini sport kit now so I'm wondering which one of the following is better for performance. It's either a malossi MHR rep or a stage 6 racing. It'll have a 21mm carb and Doppler s3r exhaust (which I might upgrade) with all the usual transmission parts and a Doppler endurance crank. Of course it will be liquid cooled. Also can someone tell me the top speed that I should be getting from my current air cooled 70cc polini sport setup and can someone tell me the top speed if both kits and possible hp figures of both the malossi and the stage 6?? Cheers.
