Great kit.

I needed a new seal and this did the job. The kit fit perfectly in my KTM and was easy to install. You can find the seal alone much cheaper, but it doesn't include the O-ring or other parts that are needed to rebuild the countershaft seal correctly. I have used this kit on two of my bikes and they haven't leaked yet.

Full engine gasket set

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

Gasket kit

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

Moose Drain plug

Works great, fits better than old one and no leaks. That's all I wanted. Thanks, but took 5 days to get here, otherwise great service.

Good Quality. Fitment issues.

This kit comes with everything you need but unfortunately came with the wrong size valve seals. Note, the bike I bought this for is a 2004 Honda CRF250x. Anyway, after some time on the phone new valve seals were shipped to me next day from Vance & Hines who actually puts the kit together. The valves and springs are made by Fraction MX so the quality is superb. Anyway, I still recommend this product for the build quality.
