Let me explain. My last ride was during a hare scramble in Oct of 09.
The bike ran fine aside from the fact that it started very hard while cold. I didn't have any problems with it all day before washing and storing it for the winter. Last week I ordered a new set of ice tires hoping to hit the ice on Sun.17th before this happened.
When starting a bike I always slowly apply pressure on the kick starter to move the piston up and down a few times "without trying to start it" , as if priming the motor before really jumping on it.
This time while slowly moving the kick starter down with my foot, I felt an obvious compression stroke. After 3 more slow and controlled kicks "only applying little pressure on the kick starter", I felt what I assume was the power stroke, the exhaust stroke, and the intake stroke without ever feeling a compression stroke again after that.
Is a valve stuck open, closed, carboned?
Is it the Auto decompression valve?
Is a Shim cocked in place a little?
All opinions welcome, please help!
