I've had my 82K miles ST1100 for only a matter of weeks and started on valve lash a couple of nights ago. To my surprise there were a number of odd sized shims (.221, .223, .218) in the right bank. Could it be they were factory shims installed at the time of manufacture and this is the first adjustment? If so, that's a testament to an even wearing valve train. I read somewhere that on a well designed engine valve seat recession was countered by calculated wear elsewhere in the valvetrain so as to minimize adjustment.
Being new to ST valve adjustments I have a couple of observations. First, it's a pleasure and easy compared to other systems with chain drive gears. Having the cylinders out where you can see everything is fantastic. I'm not sure how you can foul this job up. Set TDC, check the cam indicator notch, mark the gears with a little paint and pull the cams. The only minor problem was that my magnet would not pull the buckets. I used electrical tape to pad some channel locks and that rig easily pulled the buckets with no scratching. I am accustomed to finding odd sized shims on the Internet but in this case I could not find 2.17, 2.16, etc. that I would have preferred. No biggie because a single 5 pack of 2.15's puts the right pair of cylinders well within spec.
PS I just found this link with Honda part numbers to odd sized shims - Valve Adjustment Tips ( ST1100 ) * (st-riders.net) 2.18mm shim on order!!
