But yours is a good point that when clearance is lessening it's not going to make an increasing ticking noise, it'll probably make less.

- November 11, 2018, 08:02:28 AMLike many of the rest of you, I have never checked mine either. It's still "on my list" (has been for a couple years now). From what I remember Ratman saying it isnt' so hard that it should be a daunting task- just one more thing on the list that hasn't made it above the line yet.
Do you remember how long it took you CDD? to take of the covers and check the clearance? Seems like a couple hours is what Ratman told, but can't remember for sure.

- November 10, 2018, 23:16:19 PMThanks for that feedback. I'm not crazy about the idea of shims either buying them or replacing them, but are you saying for one thou out of spec you went ahead and changed shims? I guess you're hearing from my lazy side.

- November 10, 2018, 23:01:37 PMI checked and adjusted valve clearances on my 800 Drifter at 5000 miles. All were out of spec by a thousandth or two from the + or - allowable gap. Here is the interesting part, intake valve gaps were wide while exhaust valve gaps were tight. I assume that the exhaust valve stems must have stretched. A tighter than spec valve gap will not give you a tic or rattle indication that adjustment is needed. Our 800 engines are almost bullet proof, but I am a big fan of preventive maintenance. Peace of mind has value. My 2 cents. Happy Drifting, CDD

- November 10, 2018, 21:39:52 PMI am wondering the same thing. I've got 15 thousand on my 2000 800 drifter. I bought it with 11 thousand. I've always heard a lil ticking in motor.

- November 10, 2018, 14:21:37 PMI have a confession to make--I have never checked my valves. If Ratman was still around he would ream me good. I got almost 20,000 on the bike that I put on it so I'm coming up on 24000. The funny thing is I don't really hear any noise from the valve train, some very light ticking noise but that's always been there. Please advise. Do I have to get in there and check it or can I let it slide say another year?
