last compression release I installed was on my RT-1 (360cc single) flat-tracker circa 1970.

impressive job on the machining work. :GJ: salute!

relieves a lot of strain on starter. :thumbs:

“THESE are the times that try men's souls. The summer soldier and the sunshine patriot will, in this crisis, shrink from the service of their country; but he that stands by it now, deserves the love and thanks of man and woman.
Tyranny, like hell, is not easily conquered; yet we have this consolation with us, that the harder the conflict, the more glorious the triumph. What we obtain too cheap, we esteem too lightly: it is dearness only that gives every thing its value.
Heaven knows how to put a proper price upon its goods; and it would be strange indeed if so celestial an article as FREEDOM should not be highly rated”

I think a lot of the new motorcycles have auto valve cam now days. Centrifugal force changes what the exhaust valve does at low RPM. Once the bike is running the exhaust closes all the way.
