New to me 2006 400. Runs great, only 7200 or so miles. Wondering about valve check.
Zuki says every 4500. BUT, my local dealer - I did not buy the bike from him - he says just ride it and not worry about. He says they check them but rarely find them out of spec. - Your thoughts? - Thanks -Sirkitrider

The dealer made a very true statement....However....if they do ever come out of adjustment it can be catastrophic! :evil:
I have check mine 3 times and not needed to adjust them yet @19,500 miles.
I do re-torque the adjustment nuts when checking and found one some what loose the first time but never again.
Loose valves are happy valves and tight valves will make the engine sad. :wink:
Suzuki has the 4500 mile scheduled maintenance a way to cover themselves Justin Case. 8)

I check mine about every 10,000 miles. I've yet to find them out of spec but I always reset them to the mid point of the spec range anyway. If you have gone to all the trouble to check them the extra couple of minutes it takes to reset them seems worth the effort to me.

Thanks ScooterReno and Buffalo. At 7400 miles I won't sweat it just yet. - Sirkitrider

How do I check them? I don't even know how to access the engine

You can access the top of the engine by removing the air cleaner housing. Once it is off everything is fairly accessable to do the valve check. To get to the valves you are going to have to take the valve cover off. To do that you will need to take some of the throttle body loose. A service manual is useful to have if you plan to do the work yourself.

I did some searching in the How To section and found this thread on how to do a valve check on the early model 400. http://burgmanusa.com/forums/32-how/11790-burgman-400-valve-adjustment.html

The links in it to pictures he had in his gallery don't seem to work anymore but the steps are all there in text so it will give you a good indication of what's involved. One thing he does that I don't do is remove the seat. You can do that to get a little more room to work but you don't need to.
