I am concerned. A few weeks ago I made a post detailing my sudden loss of power on the trail and a clicking/ticking sound emanating from within the engine.
At that time Dale suggested cam followers as a potential problem. Sounding like a good explanation, but I investigated and found the rollers to be fine.
Then, after reading some historical posts, I surmised it was related to the semi-auto, comp-release, actuated by the kick start. That seemed to be it, since when I dismantled the clutch side components, I found damage on the kick start shaft caused by the decompression lever. I removed the entire semi-auto system and replaced with a plug. Still the noise.
I have adjusted valves three times. I am reluctant to pull the head, but is that my only recourse? It runs, but it ticks away like a sewing machine and usually stalls quite quickly.
For full disclosure, the breakdown happended the first ride after I installed a Scotts damper; in that process I rerouted the manual decompression cable, (hence my attention to the decompression system.) The ride lasted about one mile before loosing power and clicking. I over-revved slightly on a fast downhill, but the break did not manifest until I stopped for a road and crossed to the other side.
I am at a loss? Valve's are all I can think of, but would it run at all?
Help. Thanks in advance for your always intuitive, collective genius.
