valve adjustment - Page 2

after reading older posts on this site it seems like valve noise is normal after a adjustment

It makes no sense in my mind but as the valves wear they get tighter and quieter. A little noise is a good thing when it comes to valves. Perhaps what you are experiencing is the sound of properly adjusted valves. As humans with habit forming minds we tend to associate with engines in cars. In cars there are engine compartments, noise supression materials, and walls of metal/plastic. With a bike the engine is right in your face and up close. A really good reason to wear ear plugs.

Just to clarify 5th_bike's advise. It's possible to turn the crank until the "T" is in view and you will be in exactly the WRONG position. The 'T' indicates top-dead-centre (TDC) of the stroke, but on these 4-strokers you can be at TDC on the compression stroke (desired), OR TDC of the exhaust stroke (NOT desired).

I once spent an evening adjusting my valves 3 times because I adjusted them once (correctly) then turned the engine over a few times and checked them only to find they were WAY off. I just figured it was my own ineptness and adjusted them again. Then I realized I had not checked for compression. So, I turned it over again to the "T" mark WITH COMPRESSION and adjusted them again. On the bright side, I'm now very comfortable adjusting my valves; I can almost do it without looking.

Now, I'm not sure what would happen if you actually adjusted them on the exhaust stroke. Maybe it would run with a lot of valve noise???? Maybe it wouldn't run at all....

The last time I totally forgot to set the piston at the right point. The exhaust valves went fine (one of them was a little too tight) but at the intake it was like, wow they're really tight, am I glad I'm checking them now. :techy:

But I couldnt' get them right, and after a while I realized I was setting them way wrong because the valves were being pushed down on the intake part of the cycle... :oops:

I think it would be best to go with OEM specs and procedures than to listen to a troll. Our forum members have posted very helpful How To's about the valve adjustment and never deviated from the specs. Call the troll at your own peril.

Just ignore him. It's not like he's a big deal.

I also have valve noise after trying my first valve adjustment yesterday.

So are you saying there are two positions when you set the mark to the "T"? I thought as long as you set it to the T mark you were fine. So there are two T mark positions, one for the compression stroke & one for not compression stroke?
