Hey Brian, seems like a lot of you guys have made their own spacers/gaskets. How do you make them fit well? It's not that hard to get make a gasket out of paper, but to apply it on aluminium and cut the aluminium exactly is quite hard without the proper tools. What kind of spacers on the cylinder st...

Somewhat 'dicey' advice..............especially when oversize CB72 pistons & rings are available. You should maintain no less than 0.75mm clearance between the piston and the head/valves. DO NOT mill the pistons........that's very risky..........but the sharp edges should be smoothed..........The s...

A good friend of mine who works a lot on CB72 engines ensured be that it's possible to use them. Now the Pistons fit in the cylinder but not in the cylinder head since they have a wid...

Looking for a CB72/77 camshaft
I'm looking for a camshaft for my '64 CB72. Heard that the CB77 camshaft will fit, too. My brother's currently in New York, so I have to use this opportunity to save the transcontinental shipping costs.
