I change the oil every 500/600 miles. i asked my local yamaha deadler if i need an oil filter and he said itdoesntbhave one. can any one verify this for me with a manual or experience of the engine????

First of all Phill

How many years have you been riding a bike (excluding a pushbike)

The reason I ask is that if you've been changing the engine oil every 600 miles or so, surely you must know if there's an oil filter on the bike or not?

I'm not familiar with your bike, but I would think that all bikes are fitted with some sort of oil filter. I might be wrong.

Secondly Phill, You will get a more friendly responce if you introduce yourself properly.
