Phenomenal looking splitfire KX build. Nice to see you did the black sides/green front number plate as well. Very nice job!

2/8/2026 3:47am Looking for any aftermarket billet triple clamp SET or just the lower clamp. Already have billet top clamp, looking to add billet lower or just purchase complete assembly for 1999 or 2000 rm125 or rm250 (they are the same) Thanks

11/9/2025 11:24am I had one I got as new leftover in 08.. bike was a rocket and I feel it would probably give any modern 250 a run for its money, power wise. Chassis did feel odd and the rear shock I remember felt over dampened off the floor

My 94' RM80 was faster than that 93' YZ. They were terrible.

11/8/2025 9:00pm I’m gonna revive this.. I had a 97 KX125 back in the day. It was a big, wide, truck of a bike. I liked it in the woods or anything high speed, as it did feel stable, but not anywhere near a track. I was in my teens as well so being lighter didn’t exactly help my case with it...

I had one on a yz250. Couldn't tell the difference between the maps or from stock. Long time ago, was a beginner back then!

11/7/2025 5:54pm Was boredom searching the bay and stumbled across this, for literally my year bike. 2000 rm125. So I snagged it.. anyone know anything about these CDI’s? Has 2 maps supposedly, just need to wire in a rocker switch.

codysimoncelli Added a reply to Are older 125’s THAT slow? How can I fix this?
11/7/2025 1:07am Absolute work of art there.. I need those wheels. The cool thing about these 99-00 is that nobody really has them. Getting compliments every time I hit the track is pretty sweet. 2 questions.. any info on your aftermarket ignition? I do have the orange monster coil.. no difference. I also have this thing for it called a “roost boost”...

This one has porting, head work, reeds, exhaust, aftermarket ignition and stic block fitted, and revs to the moon! Love this bike and great fun to ride, but no comparison to my 2019 TC125 with the same mods, and the gearbox is a real weak point on it. If I was to do it again I’d have kept the RM stock and built up a steel frame YZ125 with modern SSS suspension, they’re the best mix of old-school feel with good performance and parts availability

Have you done a leak down test (either before or after the rebuild)? That's where I'd start (assuming it's not a mis-routed throttle cable or something like that). Sure sounds a lot like an air leak. What does your plug look like after you've ridden it?

+1 on the leakdown test, I have had RM125”s that leak air right through the cases due to porosity….. search 2t leak down test on Utube…this should be done after any rebuild….other things to check, as stated: throttle cable routing, carb slide hanging up due to wear, partially clogged jets, worn carb orings/ gaskets.

Dude, the STIC Super X PWK 38/40mm carb is magic for small bores. The fuel uptake right off idle is very aggressive and it creates a cooled vaporous mix. I know 125 riders that have removed the less potent meter block version. The power delivery character is linear, but it is abrupt and will pull like a ported big-bore kit with more over-rev. The peak HP has a broader RPM range, so the shift point is much less critical. On trails it can be short shifted and not sign off, just keeps pulling without clutch input. No problem running a...
