The Issue: Over the last couple weeks I have noticed a weird clicking/knocking noise when I start my bike. It only happens when the bike has sat for a while, like starting it when its cold, (by cold I mean engine temp under 100). But once it gets a little over 100 degrees the clicking goes away, and there is no notice or hint of a problem …
The noise: Kind of hard to describe but if I had to pick a sound that it resembles, it would be that of a lifter sticking on a car. It sounds like its coming from the right side top of the engine (like right around where the frame slider mounts)….
Any ideas on what could be causing this?
