Service Bulliten question (Valve Adjustment & Shims)
I just want to confirm that you do not need to adjust the valves or shims within the first 10K miles right?

And that's something I'll prolly take it to an expert for...
Note I didn't say I'd be taking it to the dealer...
I'll buy the parts and everything needed, but don't plan on doing it myself.

On a new bike I do a valve inspection at the 1000 mile/second oil service . First oil service is <100 miles for me . You might be amazed at how the valves move around in a short time . Remember the engine parts are still wearing in now .
Funny how I hear about everyone getting their valves looked at . The steelership tells them they are all in spec . That means your bike sat in the service dept for two days untouched . On the second day the tech takes it to redline around the block for you . Later you get a call to pick up your ride . I have several friends that work in the service dept of steelerships . This all came from them . And not just one steelership either . I was active duty Army stationed all over the U.S. and southwest Asia . I've been to steelships from coast to coast .
If you don't beleive that , try to do your own valve adjustment . I know for a fact it takes more than 3-5 hours like the steelership says/charges . Turning the engine over so that the cam is on the heel then measuring all 16 valves . If you need to adjust the shims , you have to remove the cams . Remove the cam chain , cam chain tensioner , timing cover and so on . That then requires a total remeasure of all the valves when you think you have the correct shims installed . Also the cam bearings have a specific torque value . Wrong bolt torque means you are off on your valve spec .
Also you need a feeler gauge that has a 45 degree angle to it . You need to get down under the cylinder head rib that the valve cover sits on and exactly parallel to the valve bucket . Any feeler gauge angle to the valve bucket will increase the drag on the feeler . Meaning you will think the valves are tight even though they might not be . It's all about precision .
