I believe the first check is the most important one, if they checkout good the first time I don’t think they will change much after that.

I've been dealing with Vickery since the 70s and I have never had any problems with them. I don't take things in for service, but they have done recalls and the like and not ruined any of my motorcycles, which is more than I can say for other dealers. Several mechanics, parts guys and sales staff has been working there for over 30yrs. Good guys. They will do you a good job.

Why they will not use another type of simpler dumper, where it is not necessary to disassemble the entire cam shaft to change a pill that is under the dumper. if the pill was up, with a simple tool the plunger would sink and the pill would be changed. Yeah ... I know ... I'm talking stupid things:):)

I like this type of system. My old FJ uses shim over bucket and a complete valve adjustment only takes about an hour. Of course it is a really easy and simple bike to work on. I also like the old screw and lock nut system. I have put thousands of miles on both kinds and not had any issues. I am sure Yamaha put the shim under bucket valve system on the ST because it is the same set up on the rest of the bikes. I am not an engineer but the only real issues I see with a shim over bucket is the weight of the shim at high RPM. I am not Valentino Rossi so I don't care!

Yamaha is a super conservative company and everything is an adaptation of something else. While they have had shim over bucket designs, the top of our engine is based in a scaled up half of a 4 cylinder. It seems to me the basis was an early R1. Hence the design for high rpm so the shim went under the bucket.

The other drawback of scaling up became the really long cam chain, but that's another set of threads.

At most, I'd stick to Yamaha's 26K recommendation, but I think you can also make the case that there isn't a whole lot of risk with letting it slide longer. And the inspection/adjustment itself is not risk free - there's lots of ways to screw things up whether you do the work or hire it done.

If you're at 16K, then postpone the decision for 10K and you can worry about it in a year or two. You may not even have the bike then - life is unpredictable.

Just thought I'd ask. I usually put 12K a year on but with a brand new shoulder inserted in January I can only work on and learn about my S10. My first real ride will be at the Ouray rally if it happens...I hope. I get a little tired of all my old BMW riding buddies....just kidding?

Dealer in Louisiana quoted me. $300 to check them and $500 to $600 to adjust. And said they have never done one before. The same dealer checked mine 26000 miles ago and charged me $425. I guess the mechanic that checked mine has moved on.

My local trusted indy shop here in Chula Vista, Ca. (San Diego) will adjust the valves (including shims) for $399 worst case scenario. Check is likely cheaper....but for that price its pretty great. If you're in the San Diego area, he's worth the drive. :)

A good shop will charge you $300-$450 for the 26k mile valve check/adjust, depending on if they have to re-shim or not. If no re-shim, only a valve cover gasket and one other. I just paid $300 for that work recently in AL. In UT it used to cost me $435 or so, with shim changes. On the '12 I skipped the first interval and did it at 52k. All exhuast valves were right on the edge of spec, running tight. On the '15 that I just had done, I had it checked at 28k and they were all nicely in the middle of spec still. YMMV. At 16k, you don't need to do this work. The header and ECU flash won't have any impact on the valve train.
Where is AL did you get this done?

A dealer in La. quoted me $485 plus tax today for a valve adjustment today. The same dealer told me $500-$600 a few months ago.

maybe they finally did one for someone and know what it takes now?
