Thank you very much mattoloRIPRIP . Thats good info.
Mike , I have run a jog/zuma kit , 50cc , it riped . My 80cc dio project is also running , but Im still not really impressed with it yet . It is a work in progress . I am waiting on the 52.6mm Stroker crank for the 120 kit . Keep in mind that my proof of concept projects are being done with cheap off shore parts . More then likely explains the lackluster results . The malossi kit was just a $50 ebay find that I was considering . I know zero about Derbi . Well a lil now .
Thank you all for your posts .
I sold my hobbit , these are nc/nu 50 projects but the same kits will apply .
