I just picked up a bayou 300 and I have a few questions what kinda grease for the rear end and front end. And what would be the best oil to use when I change the oil. Also where is the oil pump located??

 

Any gear oil for front diff and rear end. 80W90 is fine. No grease. Use 10W40 engine oil for the motor. Oil pump is inside the engine....you should view the parts diagram to see where. Don't forget the oil filter.

 

Manual should tell you gear oil ratio. Go to any auto parts place and they should have it. Valvoline makes a special ATV engine oil 10W-40 you can also find there.

 

Thanks I plan on grabbing the owner manual didn't get one from the guy i got the bike from. Other then the oil pump is there anything else you'd think it could be making the noise??
