I just picked up a 1985 honda fourtrax 250trx. I finally got it running good and was riding it around my property i shifted from 2nd to 3rd and all the sudden it acts like its in neutral i can't get any gear. I checked the shifter its self and it seems to be shifting and i can feelthe drive shaft spin through the boot. I'm at a loss any help would be great. This is my first post thanks for any help.

Took the side case off that checked for a bent or broken shift shaft but it was in good shape. Would y'all think its a clutch or a broke shift fork?

Are you able to select any gear? Can you shift to neutral?

But when you select gears are you able to select neutral to show the neutral light?
How about reverse, are you able to select that?
Have you jacked up the rear end and removed the rubber boot from motor to swing arm to confirm gear engagement?
Is there any evidence of metal/metal shavings in the motor oil or rear diff oil?
Was there any signs prior to this issue? (Clicks, clunks, bangs, knocks etc)

Well i was able to get neutral before i took the clutch cover off. I was not able to get reverse. No shavings in the motor oil. I have not checked the rear end yet. No weird noises at all no clangs, bangs, or anything was running perfectly. It did sit for 3-5years before i got it running yesterday. I rode it for about 15 minutes with no problems. Parked it rode it again for about 5 minutes and went to shift to third and lost everything.

Ok... Have you adjusted the clutch at all? Screw with lock nut near the rear foot brake lever?
What motor oil is currently being used? Was it suitable for wet clutches?

Yes i did try to adjust the clutch still got nothing. Yes i just changed the oil with valvoline 10w40 motorcycle oil for wet clutches.

Have you disassembled the change clutches and reassembled? Are they in good shape or worn? They could be stuck or jammed....

Also... After removing the clutch side casing, have you consulted the factory service manual to determine correct fitment of the casing?

No i haven't taken any of the clutches apart yet. I just stopped after taking the case off and giving a visual inspection.
Photos would help us with diagnosis, try uploading some.
Seems odd how you lost everything within seconds.
I would like to assume it would be a clutch issue or final drive issue. If it were a selector fork issue you'd have noticed symptoms before total loss. The only other total loss possibility could be a gear that has sheered the teeth.

If you can't select neutral then I would assume a shifter shaft or selector fork. Also, is the shifter tight on the shaft or slipping?
It's an old ATV now, it's hard to give a definitive answer without facts and condition confirmation.

Should i be able to get neutral with the clutch case off?
I'm not 100% sure.. I would assume so but I can't say I have ever tried. You can't damage anything, try it. Obviously don't start the motor!
