Wow...big difference. Is that bore even 2"? Are the carbs fully adjustable. How about enlarging the ports boost port, intake port and smoothing port matching the exhaust ports.Thanks very much for the compliments and comments. Took most all day, campared to a couple hours for an F rebuild, lol. At least there are no bearings to mess with, lol. Double bushing on the bottom end, single bushing on the top end of crank.
Anyone see the odd brass cap that goes over the main jet?
The bicycle does need air in the tires.
Yeah, the original C's have a tiny bore. They use a different head gasket as well. The O.D. of the cylinder is smaller and the ports are tiny. The A engines have an even smaller bore. There were 3 different size C engines.
I'll post this pic again since it really shows the difference D-600 vs. C-10
