How often should you change the oil on your bike???

 

I do mine once a month. And i dont ride that much.

I guess it depends how much you ride.

 

every 20hrs or 200miles according to the manual

I changed mine at 25hrs and 150miles, Took over a year to get that many miles on it. The oil looked good though.

I suggest going to your dealer and getting one of the yamaha hour meters. All you do is wrap the wire around your spark plug cable and stick the meter somewhere on your bike. Best $35 I spent on my Raptor (Grizz has one built in)

 

I change mine about every three rides.
