Ok before you say to I already have and always do grease my rear end on my 250x. lately ive been seeing grease come out on the sprocket side and i didnt really think anything of it and then today i heard a little screech and stopped to see what it was and i didnt see anything but I did smell something and I looked down and seen smoke coming out where you adjust the rear end...does anyone know what I need to do to fix this...If its any help there is some kind of seal sticking out where you adjust the rear end...any help would be greatly appreciated...

 

Sounds like your rear end bearings are shot.

Can't fix them, just buy a new set.
