its a jigsaw puzzle , clear the bench and lay it out ! I'm taking it you stripped it , depends how far you went too so start with piston and barrel etc etc , then gear cases , crank , gearbox internals , sort all nuts and bolts and test where they go and put with that part ! wish i could be there to walk you through it coz its really easy if you follow this and then look up all torque settings etc, have fun ! P...

Clutch friction plates are often the worn out component of that assembly. IF the plates don't spline in correctly with the basket due to some physical damage, then you should replace the basket. The clutch is comprised of an inner and outer hub that become interlocked through metal disks and friction disks pressed together under spring pressure.

Follow this link to a schematic of your 2002 honda cr125 to see how it all fits together.

look thru exhaust port turn the valve should see port open up

It is a 2 stroke motor there is no oil you put in the motor only 2 stroke oil in the tank so it will mix with the gas.

Check to make sure you haven't swapped the forks Left for Right. There maybe a design feature thats prevents swapping them.

it could be done but i do not suggest it the frame on the 125 wont take the extra power very kindly

Yes. The application of a proper pipe on a two-stroke motor is critical. The 250 pipe has way to much volume and not enough back pressure to allow the 125 motor to breath properly.Also check the ignition timing carb jetting and power valve for proper working order per Honda specifications.,
