@Tony2Strokes try raising the clip (which would drop the needle). The circuits overlap. So changing the needle position would also effect low end. I had the same problem with my 92 RM125 with mikuni tm 35mm. I dropped the needle one clip....now she rips pretty good. Although a smaller main jet is what mine really needs but it worked until I get one. I think yours could benefit from a smaller pilot.
@@brainstain22 thanks Brian, I actually had it on the second position but put it back to 3 when changing jets. But I think you’re right. I’ll move it back. Thanks again.
@Tony2Strokes anytime bud....I've been following your build. I just picked up a 2000 rm125 that the top end blew on. Bottom end seems fine. Also just picked up a 2002 RM125 that runs great but the crank bearings are making a slight roaring sound....so I ordered pro x gasket kit and some pro x crank bearings. Wish me luck...lol.
@@brainstain22 very nice! Good luck. From what I’ve heard, these rm125’s like running lean and go through top ends quickly. I wonder if anyone makes a two ring piston for these 🤔
I asked u if u sold it on another video of yours ha so ignore that 😊,,i just bought one of these,,same year and all the guy put a new piston and clutch in the thang flat rips
@@madmaxhd1748 i traded it for a bobber project. But please share for the lesson alone. I tried a lot to make it run perfect… it always seemed a little weak On the low end… but it was my first 125cc so maybe im looking into it too much 🤷🏽♂️
Where is the clip on your needle at? Its definitely too rich.
3rd (middle) position. It seems to only be rich on low end, so why would that be the needle position?

I have a 2000 and have been tuning/ racing it over the last year, how can i get ahold of you, might be able to help your super lean...
