SOURCE: '95 Yamaha YZ 125 clutch - stays in gear when clutch is pulled in
hey dude,, just thought id come in and give u some tips or 3,, i take it when u pull clutch lever in, and try and change gear it feels like your foot will snap b4 it goes in gear,, if that makes sense,, firstly mate,is to make sure the clutch cable slides freely ,easest way is to take cable off and just grab 1 end and make sure it isnt sticky,, if so dip one end of the cable in a bit of old oil ,,whilst holdin the other end ,pull and push the cable inner, this will **** up a bit of lubricant inside the cable ,, keep doin this each end till free to move, ,,next step if the cables ok,,, and may need help if u dont no,drain the oil out,,and as u r sat on the bike is to remove the clutch casing on the right hand side of the moter,where the bottom end of the cable goes,remove the casing being carefull not damage the gasket,,then u will see clutch plates and friction plates housed,, undo the 7 or 8 spring loaded bolts carefully take the first fibre plate out then metal friction plate then another fibre plate and so on,, wen u take the 1st plate out place that on the bench ,stacking each plate on top of one another, cause they have to go back in as they came out,,wen out,,u need a piece of wet n dry paper ,or fine emery,,and just wipe round both sides of the fibre plates taking the shine off them,as u put them back in,, put casing back on with a decent gasket,, oil back in cable on, make sure cable has no free play on the lever so wen u r about to pull lever in it bite straight away,, start her up, warm it up and try it,,any probs still il eat my shoe,, take care m8

You need the selector in the gearbox renewing. Sounds like it`s bent. Happened on my yz490 years ago
SOURCE: 03 YZ 250 won't shift into 3rd
You have a bent shift fork. The repair means removing the engine from the frame then tearing it down into about 75 parts which will then allow the bent shift fork to be replaced. This is not a job for the amature mechanic. Wish I were there with you to guide the repair.

You have a bent shift fork. The repair means taking the engine out of the frame then removing the top end, removing the flywheel and electrics, removing the clutch , shift mechanism and kick starter and a few other parts. THEN you are ready to split the gearbox to remove the gears and crankshaft and then the shift drum and bent shift fork. Next you get to put it all back together. This is a pretty big job for the home mechanic.
You will need an impact driver, flywheel puller, case splitter and torque wrench plus the normal screwdriver, pliers, etc.. Alternate to the special tools is taking it to the dealer and say "Fix it".
I normally tell people to take it to the shop just so they don't get into such an involved project.

How do I put this? Yes, you have a bent shift fork. And, yes, they can get bent in a fall, a dump, a drop or whatever terminology is used. The fork engages into a collar on a gear that slides left and right, (slider gear). Large "pins" called "dogs" are cast into the side of the gear. The dogs engage into holes in the side of the gear you are shifting into. Question: What happens if the bike drops on the clutch side and the shift lever is forced down, moving the slider gear to engage first gear even though the holes in the side of first gear are not lined up with the dogs on the slider gear? "You get a bent shift fork" is the correct answer. The force of the shifter lever moving the shift fork into the solid parts of first gear, (not lining up with the holes), is easily great enough to bend a fork. That pressure has got to go somewhere.
The repair means removal of the engine and a complete tear down of the engine/gearbox. The replacement of the bad fork is a given. But I suggest you do some preventative maintenance now, while the engine is apart anyway. Replace the sprocket shaft left bearing and seal, both crankshaft bearings and seals, shift shaft seal and the water pump seals. These are pretty low cost items and replacing them will mean you have pretty much rebuilt the engine. Have the dealer check the shift shaft to be sure it does not now have a bend in it.
Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock. http://www.babbittsonline.com/pages/parts/viewbybrandand/parts.aspx
