Lost a tooth...
 

I drained the oil out of my 125xc today - winterizing a year late - and found a gear tooth stuck to the magnetic drain plug. Ooh - hate when that happens.

A couple of years ago, the waterpump shaft snapped in the bike, causing the waterpump innards to fly apart, with the engine side innards getting sucked into the primary drive - caused a fair amount of broken stuff, including shattering the waterpump drive gear. Of course, I didn't notice anything until the bike overheated and seized. Unfortunately, I don't exactly remember if I found all the pieces of the shattered waterpump gear. I couldn't even get a new primary drive gear, so I had to rebuild the broken teeth on mine with welds and grinder (still going strong) I do seem to have a vague memory of not being able to find one of the teeth...

The gear tooth I found is skinny, maybe 1/8", so it's surely a waterpump or powervalve drive gear. Sure hope it is a long-missing piece that finally made it's way out. Everything else seems fine with the bike...

TEAR it DOWN !!!!!!!!!!!!!!!!!!!!!!

Well, those gears are on the primary side so its an easy inspection with just the primary cover removed.

When I read the title of this thread, I thought it was about the killer kickstand again.

Yea - I think I can even get away without draining the radiators, but I'm not sure. I'm getting more confident that the tooth was leftover from the last blow-up though. It'll be spring in any case.
