I changed the oil awhile back in my 03 450 and there was a filter i found in the garage that was for my dads 350 big bear. I read on the back that 450s and 250s and a couple of others would also take it. It was a fine metal filter other than the usual paper ones. Is this reusable, and is it safe to use in my bike because it said there are some years that it wouldnt work on on the back of the box It was a yamaha filter. I dont have the part number though.
