I just purchased this bike about three weeks ago and it was running ok, had some stuff in the float valve and cleaned it and it ran good agian. It was reading high on the temp gauge, however I could still hold my hand breifly on the top of the heads so I suspected a faulty sending unit and continued to ride another ten miles home. The next morning it started hard and was having a hard time idling, the next time it started even harder and would not idle at all, warm or cold. Then it would not start at all. I have checked spark, compresion is about 50psi cold with a rubber compression adapter. I even tried spraying either into the system and got no response, not even a burp. I have cleaned the carb thuroughly and carefully, but the either thing is seeming to point me to a different problem. If in fact I did run the engine too hot for too long what could happen, and wouldnt the compression show up less than 50psi or is 50psi bad for a cold engine?

also tried these things out
pulled the plug and submerged in fuel(then removed)to see if the extra fluid would foul the plug, fired the plug Niceley super solid spark.

Earlier I mentioned that I was getting 50psi cold, the only way I could actually get 50psi was to bypass the automatic decompression device. With the auto decompression device in line I could only get about 25psi or so. While I had this device bypassed I installed the plug and tried to fire it up using the carb in line, I never tried either at that point. Still got absolutley nothing.

could my timing be off?,chain looks good, proper tension and clean,no funny sounds like something broken or the like,,is 50 psi too low to allow for combustion, even a little pop or burp

and if I have strong spark and still get nothing with either, does this not partially rule out the carb as a problem, seeing how I am adding my own highly combustable mixture.

Help,,,, I am about to pack it up and send it into a shop!!!
