I can only get about 40 km/h from my 66cc skyhawk
I get less speed than that out of my 66cc engine, and it has a modified cylinder, a high compression cylinder head, reed valve intake and Walbro style carburettor, Jaguar CDI and a modified exhaust.
There are times when it's struggling to achieve more than 10 mph; working it's guts out.
