Excellent valve set!

Comments On Jul 05, 2010:Bought these on a budget figuring I would swap them out for titanium later but they have been working so well they're staying in. They don't seem to bother the high end rev and are very reliable.

pretty good

Matt in CA

Comments On Feb 01, 2009:These valves are good. can't say they are great because I can't really tell the difference. great money saver and w/ replacement valve springs and seals its great. I have an 05 CRF250R and I can tell that it wants to stay on the gear longer when I let off the gas. pretty good. good investment.
