My 400ex has never sounded better. New tensioner, guides, and chain fixed the noise. Metal bottom end gasket was cool too, didn't rip while working on it.

We agree, these small maintenance steps can make a big difference in the overall performance and sound of your vehicle.

Well my mechanic said it was some good parts in the box. I'll let you know how the rebuild goes. Great I hope
