So most of you are aware that when the stop tabs on the powervalve system start to wear, the piston rings will scrape against the actual powervalve itself. This in turn causes a nasty failure.
Now I don't know if this has anything to do with the failure I experienced because of this, but when I first got my bike, I noticed clicking noises within the engine. This would happen if I was in too high of a gear (well below the powerband) and giving it a lot of gas. It sounded like a smooth rattling until I finally got near the powerband, then it would disappear.
Is that noise the piston rings kissing the powervalve because it's not fully open at low rpms? Or could it be something else. I noticed this the other day when riding some wide open sections. What could cause a rattling noise like that, obviously RPM and load related? I replaced the powervalve stop, but not the actual powervalve itself. I'm guessing the stop put it back within spec, but maybe not.
I'm putting on new rings soon so I'll inspect for any damages.
