Default Re: Why are the engines called 66cc/80cc need info

My oldest engine is my only odd ball to speak of, it was advertised as a Red Bat Kit by BGF back in 2009 and was listed as 66cc, it has the low dome piston and the 6mm jug studs, the jug and head bolt patter are smaller than any of my engines with 8mm studs and the old Red Bat is the weakest and has the worst vibes of any of my engines, never done a single mod to it but tune the carb and it has well over 2000 miles on it now and still starts every time and is very reliable and comfortable at 28mph or less pulling a 24" rear wheel with a 32T sprocket.

I would love to have this engine set up with a better balanced crank some day but it may just end up on the shelf as a trophy of sorts since it was my first china girl engine.

I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
