Few Qestions Piaggio Zip ???

will a stage 6 crank work with a Mhr replica kit
and how effective are the malossi secondary gear up kits and isit worth buying one well my engine is in bits thankyou for your help

 

the S6 HPC is a great crank, have one on my bike, will support twice what that kit throws out, the MHR rep, is nick named a sport plus kit, or the lower end of the mid-race kits.

gear up kits that don't come pre-pressed are a hassle for the home mechanic, who hasn't got access to a machine press, get pre-pressed ones or a primary gear up kit. They come in various ratios, get one that is a small % upgrade, or you will lose all acceleration and struggle on the slightest of inclines.

you don't have to have a gear-up kit, but it raises your top speed, lazy cruising, and protects the engine from revving it self silly all the time.

 

thanks for the reply now got a clear'er view
