So I picked up this 2001 Rm125 for $500 off a good friend of mine. He had it completely dissassembled when he called me to come pick it up. At first he asked if I could fix it for him, and I told him I didn't really have time because I didn't want to work on it.... about a month later I got a call to come pick it up!
He was having an issue with the bike going into second gear. You could pull on the shifter as hard as you wanted and it wouldn't budge! He had the engine completely apart when I got it. So I had to diagnose why it wouldn't go into gear. To make a long story short, he had recently purchased from someone who had "rebuilt it". Come to find out second gear was installed backwards on the countershaft! Don't ask me how it went together, but it did!
So I ordered a few new transmission gears that were ruined, and put a new vertex piston in just for safe measure. It didn't need anything after inspection as it was just rebuilt! I put it back together and rode it a few times, and raced it twice as our season in New England is coming to an end! It runs great, and will run even better after a few key upgrades this winter as I clean up and build it!
I'll try to keep the updates flowing! Here are a few pictures!
I put a 2004 style front brake line on and a Brembo Master off of a 2014 KTM. Bear with me as I try to make this post off my phone! Nearly impossible!

I was able to chuck the axles into my drill and clean them up with some 1000 grit sandpaper, and some scotchbrite! They came out awesome!

If you haven't already, but the power valve actuator rod from the 2002. The 01 actuator rubs against the cog and breaks
Here's the one I bought.

I got those on ebay. I was at the right place at the right time! They were $50 shipped!
The correct WC part number is 15-337
