1982 XC 125 Question

[Chaz955i]

Hi All,
First post and first foray into the world of vintage bikes. I picked up a 1982 125XC in good condition but in need of a freshening. I'm tearing it down to the frame to get an idea of what can be salvaged vs what needs purchased and embarrassingly enough, ended up stuck at the front wheel. What is the proper way to remove the wheel on these things? I assume you would loosen the axle block on the throttle side and unscrew the axle using a breaker bar through the hole in the axle. Is this right? I got some movement but it wouldn't break loose and I don't want to go nuts and possibly break something. I can't imagine anything weird like reverse threading or something like that.

Any help is appreciated.

Thanks,
Chuck

loosen axle nut then only pinch bolt nuts on side that does not have the spacer. This stays pinched.pull out axel

Thanks, this makes sense. That axle might have never been removed so it may be a bit frozen.

Hi, my forks are the 40mm. I finally got them apart. It appears the axle sleeve is not a stock part and the axle was actually threaded into it. Once I figured that out I was able to get the axle loose. Checking now to see if I can find that sleeve NOS. If not shouldn't be too tough to make one. Thanks again for the help on this. These bikes are pretty straightforward but working without a manual does mean flying blind a bit.

Another question. I was looking at the parts microfiche and in the engine build I see no part number for a head gasket. Did these things come machined so good they didn't use a gasket or do you just layer something like Yamabond on when rebuilding?

Thanks again,
Chuck

I pulled the head and cylinder to check the condition of the piston and bore. Everything looks nice and clean. Do you guys recommend any type of prep to the head and cylinder mating surfaces prior to reassembly? First bike with no head gasket so this is new. Also, what is the recommended torque when re-assembling?

Much thanks.
