    good fit for 03 SV650S

    Fits fine. Keep your old o-ring as this does not come with one.

    Great Deal

    2008 FZ1- Fit perfectly, no 'big glob of glue' on the end holding the magnet in. Nice black finish, we'll see if it holds up. Same exact length as stock. I'm actually kind of excited to see what it pulls out of the oil at the next interval. Cheap insurance, money well spent!
