finally got around to checking the valves on my 92 klr650 with 14000 miles. to my knowledge they have never been checked. the left exhaust and left intake were a little tight so i swapped out the shims to get them back into spec.
it has ran great since day 1. i thought it started good before. now i can't even get my finger off the starter before it fires up.
took maybe 3 hours total, start to finish (not including waiting for the shims to come in the mail).
Loingrader - Doing that job in 3 hours you should be on the Kawasaki race team. It took me twice as long. Probably has something to do with me being retired. I found one exhaust valve loose out of spec. At 4k miles on the bike!
The really fun part of maintenance was when I pulled the rear suspension apart and greased the bearings. From the factory they had just a smear of grease, probably just enough to keep them from rusting. All I have to do is muster enough ambition to do the steering head bearings and the clutch cable.
Well Done

those bearings are a messy pain, BUT, it will save you from replacing all your suspension bits down the road.
