I'd suspect that "auto" is really a variable ratio/diameter set of pulleys and a belt. One of the pulleys will either be moving apart  to the shrink the effective pulley diameter, or, not separating when it is meant to be separating, and so causing the high revs and no top speed.

The struggling up hill might correct itself if you fix the pulley problem. Does the engine seem to have full power when it accelerates away from a standstill, or perhaps at mid speed it might perhaps to have full power ? If it seems to have full power at some speeds (the speeds the ratio it's stuck in suits), and if it isn't actually missing uphill, then I'd concentrat5e on getting the belt drive cured.

No it seems to pull away slowly than I would suspect also when it is struggling uphill I can release the throttle almost half way before the speed drops anymore ,

Sorry for late reply only just found your message

It sounds like the variable ratio belt drive system is playing up. You aren't mentioning missing or backfiring or cutting out or anything that suggests the engine isn't running fine, and those symptoms could be caused by the bike being stuck in a high ratio.. I'd look there first..

      Hi all,
      Looking for some help on a starter/bendix issue. Can Am outlander 450 2017. While cranking to start, the starter spins and engages into the ring gear. After a few seconds the bendix retracts while still spinning and there is no damaged teeth on the drive pulley.

      My 1992 TRX00 recently stopped firing.  I understand this is a common problem. I have ordered an aftermarket CDI unit.    TJ

      I have a 1990 Honda fourtrax 300 2x4
      I rode the other day for 30-45 min. Switched it off and now it is completely dead..
      battery is fully charged, fuses are good . WILL NOT TURN OVER ,
      headlights won't turn on , No neutral, reverse or oil temp lights . Electrically it is completely dead !!! I replaced the key switch and CDI box , STILL NOTHING.
      I bypassed the neutral safety switch and grounded it to the battery and still nothing !! I used a jumper wire on the starter Solenoid , the motor will turn over but not start . I even bypassed both fuses and straight wired it to see if I could get a neutral light or headlights still nothing . What could it be ?
