    flywheel weight

    Works great- just right for the YZ250 for woods riding.

    Top end bearing

    Good OEM substitute. Used one on my last top end without issue.

    Gasket kit

    Good quality gasket set. Had everything I needed including multiple thickness base gaskets to properly set head space. Would buy again.

    Shim Kit

    Glad I bought the kit, better than buying individual shims at the Honda shop. Fair price, quick delivery.

    Was good...

    Fit great and was an easy installation but blew it first time I took it to the track.

    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!
