Hello guys ,I have some questions about valve adjustments ,
I found this tread and decided to subscribe in instead of posting new one.

My bike is 1997 m900 which I bough soon and which I drove for around 40 miles max. before the winter came. Then I decided to change the belts and do the valve adjustment. The exhaust pipe right after the vertical cylinder shines if the engine works on idle for around 4-5 minutes /when it is dark/. A friend of mine said that it is time for valve adjustment.

On the vertical cylinder I measure

Intake opener: 0.003"
Intake closer: 0.006"

The exhaust opener is so tight that I can't stick in even 0.0015".

What I need to do ,take off the opener shim and shave it with sandpaper till get 0.003"-004" clearance? The intake closer is too loose I think ,should be 000"-0.001" from what I read.

The same is with the horizontal head.

I.O. 0.004"
I.C 0.005"

the exhaust opener is too tight ,I can't measure it.

I believe all the measurements I did are correct, I double checked with another engine rotation to TDC. What are my options ,can you help? Thanks.

First, I don't think you're supposed to do this with the engine hot. Second, your best bet, instead of words, is to either buy this video -- http://store.proitalia.com/desmo-val...d-p-99887.html -- or at least to watch the youtube videos --

I never said I did the measurements on hot engine. I've been watching the videos on youtube, and I read a lot. I understood the principle of valve adjustment ,but I am confused with the measurements. The openers are good ,but the closers are too loose ,and both exhaust valves are unmeasurable , is this a normal wear, or I am wrong.

I can check them now with the belts on but my first couple adjustments it really helped to just take the belt off to check it like in the CA video. Since it need to come off anyway I would try that before you start thinking about adjusting anything.
