Re: Just got one, now looking at a zocchi bike
I have questions every day, lol. Don't know much about Zocchi stuff, they usually have their name on the pump, my blue alum BZM pump for my BZM W/C cyld/head engine I am building is stamped. If you look at the last phot of the GRC pump, that's a 80mm Polini bell and housing and a 78mm BZM 2 shoe racing clutch. I have a 40mm Polini scratched cyld and good head here that was on my 50cc Banshee Sho clone Polini. The China engines are real close, but junk compared to a Polini. You probably have 12 to 14 hp, Redline is over 13,000 RPMs, all my clutches engage around 8,500 RPMs where all the power starts.
You better hang on to your Go-Nads, remember, your sitting on the rear tire, it wants to wheelie all the time. My Polini 910 Carena now has a 40cc 36mm bore and 39mm stroke Polini 5 port air cooled engine, modified reed stops and custom carbon fiber reeds, have a real 14/14 Dell SHA carb going to replace the China 14mm on it now.
