I've found out my bike has low compression. Its at 155 psi (warm), manual calls for 184 +/- 28 psi. 184-28=156. Is there any need for concern? The motor like I said many times runs like a new bike. It has 58,000 kms and is bound to be getting a little tired already. Is 155 psi something to be concerned of? Rebuilds are very expensive and I don't think it NEEDS it. Doesn't burn any oil, maybe it could use a valve job? Or should I look into getting the valve clearance set, if that makes any difference? I'm assuming thats the reason why I've been dissapointed in the power. I do have a K&N filter coming in the mail and I'm gonna order a jet kit today.
