CRF450 bike chain. stock 400ex chain is a 3/4 row while the CRF chain is a 4/5 row i believe. it is an HD chain, and 1/3 the price of a stock 400ex chain.

taking off the rocker box to get to the cam. the clutch cover, clutch basket, innen hub, oil pump gear, and a few other gears under the clutch cover, timing chain tensioner.. all in all about an hours job or so, maybe a little longer. not that hard to do.

Any time you do a rebuild it should be on the list of things to do, at $25, it should be done at least once a year anyways!

Where can you get them for $25?

I need to order one quick when I change to an 11:1 and stage 1.
