Edited Date/Time:
Hello all.I have been following a lot of the 2 stroke build threads and thought I'd finally share my own. I have 2007 RM125 that I got from trading my 03 Banshee that I ironically got after selling my 06 RM125 
Lol lets just say I didn't realize how much I loved this bike until I let it go.
But anyways my plan with this bike is to make a really good beginner's motocross bike. I have actually never even been to a motocross track. I normally spend most of my time woods riding but I want to start spending more time on the track.
Right off the bat I could tell that someone put some time and money into this bike at one point. The first thing I noticed was the initials J.M. on the cylinder and this bike hits really hard in the mid to top so I think its safe to assume that it has been ported. Much different from my old RM but in a good way. Does anyone who may be close to the Arkansas/Missouri area recognize these porting initials?
The bike also has vforce reeds, an over-sized motomaster front brake rotor and a motomaster rear disc as well, an fmf factory pipe with the shorty silencer, and T.M. Designworks chain guide/slider. I think I have a really good base to start with
Now for the issues that I'm already aware of: The steering stem bearing was getting stuck and the linkage bearing were dry and starting to rust. They are both still good enough to be cleaned and redeemed but this puzzles me because the linkage bearings look brand new but they're rusty
Also the air filter has no holder but the guy claimed to have just bought this filter brand new.
He couldn't give me any details about the parts on the bike and I don't think he really had a clue. He says he bought it about 8 months before we traded and it makes sense. I would guess whoever sold it to him did a really good job with it and he almost trashed it. But I'm here to save the day
This is the day I brought it home. I took off the ugly graphics that were on it
I started the tear down a few weeks after
Thats good to hear. I should dig up his number and see if he has this bike on file so he can maybe tell me what he did to it..
I tapped the little cage in too far and it deformed it so the needle bearings wouldn't go in. I was thinking no problem I will just take it back out and use one of the old cages. Wrong!! I applied heat again and tried to remove the cage but it just broke off. I had this same exact problem with my other build and I had to use a dremel to remove the cage. This is really frustrating because I think this is a design flaw. Anyways don't know if I want to deal with this linkage arm or just buy a Pro Circuit arm.
