Does any one have one? I have just passed 2500 miles on my 99 Xplorer 400. It starts and runs fine, but isn't nearly as responsive as it used to be. I was thinking about putting in a new needle & seat and try to clean out the pipe as well. I can borrow a compression tester to see how the rings are holding up.

How many miles do most people get out of a 400L engine before the top end needs to be rebuilt? How much does it cost to rebuild the clutch?

Thanks,

DD
