wiseco bottom end rebuild kit

I had no issues with the kit, how ever I did find the prices and postage to be mis leading as I am in AUSTRALIA. Beware of conversion rate.

Not correct

So, if you order this tool for a Yamaha 450, be careful. This is NOT the correct part.

Full engine gasket set

Good kit for my RM 250 1993 project/rebuild. The team at Motorcycle Superstore were extremely helpful!

works fine

Went in okay. One of the top o-rings was a pain in the ass, but it seemed to work out in the end. It recomended drilling a hole, but my old piston didn't have one, so I didn't feel like drilling my brand new piston.

Gasket kit

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