RG500 Rebuild Part 3 rotary valve timing

500 rotary valves are in correct timing with each other. This insures the cranks are timed correctly with each other. It is important to verify correct crank timing as it is very easy to be off by a tooth which causes high vibration and diminished power. Also, I turn the cranks by hand so the rotary valves and both cranks spinning can be seen. This is the only engine a civilian can spin two cranks on, and it looks cool.

2 stroke? why are 2 cylinders firring at the same time its like a flatplane crankshaft ,why not 90 deegres appart from eachother wouldnt the power output be more smooth?

Riding bikes is all about having fun :-). Even when working on them I like to think about the reward, riding, I get for my efforts and how much I get off on it. Hope you’re having fun with your Gamma too.
