Coil Over Identification

I would check with the local Yamaha shop. Looks about the same size as the adjustable coil over on my Raptor 700R.

On a side note. When I did the exhause on my 65 about 6 years ago I made 2 cut outs for the tips. I thought I was the only one with that way cool idea. Guess not. Your looks exactlly like mine sweet
