Hi there.
I'll like to know how does the power valve works in the combustion process. I only know that in high RPMs, the valve "opens" up to allow more exhaust out but do not understand how it works in relation to the exhaust port.
I notice that on my DT200WR, on the left side of the engine block, there's a "cam" with two cables attached to it.
How can I fine-tune the bike using it?
