Thank you, that makes me feel more confident. I will try it myself but so far they seem fine.if you've ever done adjustments on other bikes, the ST1100 is the easiest by far. They don't go out very often, but if you need to swap shims the cams come out with the timing belt in place, no timing chain to have to deal with to remove and replace them. You still need to pay attention to aligning the cams on installation, but its easier than on the typical cam chain bike.
