1983 125xc

So I lacked until this point to check exactly what model I have. I just found out I have an xc and not a Wr/cr can someone enlighten me on some specifications or a website. I can't seem to find one with the specs. And does anyone know what carb I'll need. I thought I saw it was a 38 mm but I want to be sure as I'm going to re do the bike and make it look nice again.

XCs are long travel CR suspension on a WR frame [bash bars under the motor rear fender loop non full floating rear brake ] not real sure on the motor differences on the 125 but the bigger bores are a mix to the only thing they get thats theirs is a middle weight flywheel and a warp drive 6th gear and unless you plan to stay pinned in the top two gears i would throw that 38 in the bottom drawer for a different project if it was mine i would try a 34 maybe even a 32 if it was a Lectron

It's an 83 and I enjoy the bike. I'm not giving it up not after everything it's done. The bike runs and does so pretty well. I just need to know carb size. And 9/10 times I'm usually either not past 4th on a trail or full speed down the road

WELL A SMALLER CARB WILL HELP ON THE TRAIL

Ohh I know what your saying. It flew over my head. So I'll f I go with mikuni you think 34 mm?

what carb is on the bike now, and why does it need replaced

The carb doesn't run well. And it's been cleaned multiple times. It's a mikuni. But I don't know what size.

got a ruler ??? im pretty sure those are 38s

That's what I read. I'll measure tomorrow when I get the chance.

Thank you

xc is pretty much a cr motor with the lighting flywheel and different gears.

Would you say it's between a cr and wr gear wise?

Xc is wr gearing, with cr suspension. You need the check the primary gear ratios and the final drive sprocket ratios.

What do you mean?

Some of the gear ratios are different between the cr and wr. Go to the tech spec area and look at the next page on the 125's it gives the teeth numbers and ratios.

Alright thank you

The bike came with a 38mm but it needs a smaller one. The problem is the smallest size in the same physical body is a 36mm which is what the 84+ 125 came with. I have used a 34mm which works even better but it is not a direct bolt on like the 36mm because the body size and the OD of the spigots are smaller and require you to make adapter/spacers.

So if I went down to a 36. It would bolt right on. But if I decided I want a 34mm I would have to build and adapter or find one to connect it to the motor. And I understand that it needs a smaller one. It dumps gas into the motor and the motor isn't mov My Fast enough to clear it out. I don't know if that's the reason my bike takes for ever to hit the power band or if it's the fact that the xc take forever or whatever the reason.

And if you guys know a place I can buy a 38-34mm adapter for a mikuni 34. Please link it I'd like to run the bike with the carb I need
