Re: grc-gp don't know much about it would like to
The A/C Euro 6.2s, have twice the power of a stock 49cc Cag. I think my 40cc Polini A/C is a 4.2, cause the side ports are very small. There are some numbers on the cyld, it may be a #2. What they do is put a narrow cast in divider and call it a 5 port. My 50cc ( 46cc ), C1 the cases did not match the cyld ports especially the rear/top 5 port. I Dremeled all the ports and made the intake port cases and cyld a bigger smoother pathway.
I woke up and it finally dawned on me the other day that all I need is new BZM cases to build, at mid-south they are $233 + bearings and seals. Over time from gpedcruisin, got an alum Euro radiator, w/ new blue BZM water pump, a real 15mm Dell 'Orto PHBG round piston carb which will be bore from 19 to 21mm, BZM 37mm piston, ring & cyld w/ head still mounted, hp BZM clutch housing, have new BZM 2 shoe racing clutch, BZM silver crankshaft, 40cc BZM racing exhaust.
I want a Euro engine in my GRC GP, so Bad, after I port the BZM cyld and cases, it is going to Fly, lol.
