Ok hi all, lemme start by saying I'm very new to anything with a motor. Ive never worked on an engine before 4 months ago.
I have a close friend who was life changingly injured in an accident on his motor cycle some ten years plus. He asked me one day why i never drove. I was always on a bmx bicycle! So I started thinking motors.
I bought my first 4 wheeler...polaris trail boss 250 2x4. It was a blast but I wanted something more to my roots. Bmx. So I bought a bike...well it set for ever....i traded for a smashed up Honda crf80f. Rebuilt the front forks, clutch( yes, me!) And was off like a rocket(Well a slow rocket)!
Soon I upgraded to a 1998 cr80br fully decked out for racing. Well I didn't quiet get the hang of it so I traded it off too. Then came an xr100r that I dumped all the water from the motor, changed oil 3x and it ran like a boss!
Now I'm riding a 03 crf150f and in the middle of rebuilding my 1997 cr125r(which is our topic) and I find myself replacing the crank, well I do and it working....except now i cant get the gears in the transmission correct. Case back together and it won't shift! Someone please Gove me the correct pattern for the 97 cr125r trannie!

Go to rockymountainatvmc.com and look up OEM parts for your bike. It will show a transmission diagram. The gears will not shift or spin correctly until the cases are fully pressed together. You need to buy a service manual or go to cyclepedia.com (if they have your model).
