Does anyone have carb specs. for a 1976 MT125??
Just finished a rebuild and the bike is running but I need to go over the carb.I'm looking for the stock specs on the Keihin carb. that's in it. I'm having a hard time finding the numbers that are supposed to be stamped on the body.
PE Type?? Main jet? Slow jet? needle part number??

Thanks dude, that should give me a start. It looks like a new needle and seat might be in order. The needle is stamped 07100, must be an oem number. Maybe Sudco can help me find the right replacement.
Thanks again,

You're right about OEM number. And they are really difficult to find. If anyone can help, Sudco can. I finally gave up on my MR250 and just bought a new Mikuni carb from Sudco. Of course, I then had to experiment with different jets, needles and needle jets until I got it right.
