A Yamaha Blaster not going into gear is typically a sign of an issue with the clutch. To troubleshoot, try to adjust the clutch at the lever. If this doesn't solve the problem, the shot clutch pack may need to be replaced.
it is most likely your shift linkage that runs from your shifter to your gear case tinker with that and she will most likely work again (it is the rod that is on the left side when you pull off the side panel)
Signs of a clutch going bad, When at a stop it is hard to shift into gear.When driving off from a stop the engine RPMs increase but the vehicle speed doesn't.
Your Yamaha Bruin may not shift out of low gear because something may be wrong with the gear box, so you should have it checked.

It slips in gear, takes along while to shift up, revs more than usual on hills, won't back up on steep hill.
Yamaha Viraho 750 holds cca 2 dcl of gear oil. I think it will be about the same.
