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.

hot rods crank

great crank but after shopping around a bit more I found the same quality for a lower price. my rebuild could have been cheaper. great delivery, and installation was perfect

04 yz250f

I thought it came with clutch cover gaskets also. Wrong. Just head gaskets. No worries works just fine for my 04 yz250f.

Cost Benefit

Full engine gasket set

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

grayson (edmonton )


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.

flywheel weight

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