Gentlemen of almost infinite wisdom, I present this problem ...
Last year I was brought this particular bike because of a no start condition. It turned out that three of the four valves were totally coked and would not seal. That issue was resolved and the bike went back to its' home.
It recently found its way back to me, first for oil leaking from the cam cover (not enough goop on the half-moons - it had been sealed when it left but apparently loosened up over the winter) and an apparent coolant leak.
The coolant "leak" is actually discharge from the overflow, which is not surprising given that the head pipe will glow red if the bike is stationary and idling for over 45 seconds. The cap is a Bandit or Pit Posse rated at 1.6 bar. The fan runs and dumps a lot of heat. On the road I could get two or three miles before the pop-off popped off and coolant dribbled out. I'm going to see if the new 1.8 bar cap from the '11 2Ts will help with this.
More troubling is a hanging idle. The bike starts well, runs at a fast idle, and then slows down somewhat (but still not slow) when it warms up. The engine speed dips when you start to ride away, but tends to hang up when you release the throttle. I can pull the idle down with clutch out brake applies, but I would rather it drop on its own. Like so many others stated, I believe the bikes owner has had every sensor checked for function and they came back positive.
Thoughts?
