bought an rm 125 that the guy pulled the carb off because it was bogging. bought a differnt one for it but it didnt fit and decided to sell it. i got the original carb (im pretty sure) but the slide that was on the bike is too big for the carb. im guessing from the other carb he tried...

RM250racer Started a new thread Drill holes in my piston?

02 cr125. Brand new oem cylinder and a pro x piston kit. There's no holes where the exhaust bridge is, the kit says nothing about drilling holes like how the Weisco kits do. Should it still get two holes? Thanks

2002 cr125. When tightening the piece that goes to the shock and swingarm to the link arm, it has zero movement. Back It off an 1/8th of a turn and it's smooth as butter. What can cause this? Without the pivot bolt going through, the two peices themselfs fit nice and snug. Ive never seen this before.

That's what I was thinking but it looks like someone has just rebuilt all the linkage. and everything looks straight. Maybe mis shimmed

got a 01 yz125 that i bought with an athena cylinder (standard bore) and 2 piece head. The kid put it together and the piston was hitting the head enough to not allow for full rotation. I verified that the crank (hot rods) and piston (Wossner) are correct for the year. The cylinder and head look untouched as far as...

The bike is a 76 dt400. Could anyone tell me what the thread size is for the countershaft nut that holds the front sprocket on? I looked at Ace and Menards and nothing seemed big enough in fine thread. Thanks in advance

The vp 5 gallon cans are great but a little expensive for a gas can. for the "eco friendly" you can drill a hole and make your own plug to use as a breather.

I don't own any thread gauges, but that was my first thought. Hardware stores seem like they won't be any help. Biggest metric was a m18 and that wasn't very close at all. I'm hoping I can find the exact size and then start calling around finding someone that might carry something that will work. Thanks for the responses.

I have a 92 cr 125 that wants to run away only with the choke off. the bike will start first kick with the choke on, after 30 seconds or so turning the choke off the bike acts as its WOT. Choke back on and it quickly goes back to a normal idle. It has power while riding with the...

Okay, so I went through the carb again, everything is clean and clear. same problem. i pulled the flywheel/stator but im not sure as what to look for visually? its seated and free of cracks/tears. Also, I noticed that the coil isn't original. It doesn't span the gap between the mounts, its short about an inch. could this be a...

does the choke circuit bypass the pilot jet? checked every mating surface for leaks including the left side crank seal with carb cleaner. Visually nothing looks out of place either, I havent pulled the stator to look at the crank seal though.
