does this oil filter come with the o rings?

o rings that are not affixed to the oil filter No.It comes just like you see it in the picture

will this fit a 1980 Yamaha XT500?

This is what I use on my motorcycle mines a 650 Yamaha classic 25,000 miles on it was like a champ

will it fit a 2007 Yamaha 650 V Star?

It should and I looked it up on the K&N site. Looks like it will work. from site - 2007 YAMAHA XVS650 V-Star Custom 650 - All Models Oil Filter KN-145 https://www.knfilters.com/search/appsearch.aspx?type=ps&year=2007&make=YAMAHA&model=XVS650%20V-Star%20Custom&engine=650

do you include all 3 o rings

I use it on my Kawasaki ATV and it fits perfectly. Never needed to add anything so I suppose what ever O rings are needed are either on the filter ends and the one of the metal cover is reused.
