Service is more than oil changes. Consider this:
Valve adjustments on DOHC bikes generally require you to remove the cams (shim under bucket like KLX and I think YZF) even though getting the feeler gauge under the tappets on a RFS could be easier, It is still loads easier than taking the cams out then going to a dealer for a shim and finally putting them in again.

Take the cams out???? Street bikes have been using the shim and bucket system since the early 80s and I've never removed a cam to change shims on either my 82 Yamaha 750 or my 88 Kawasaki 750. I have not worked on a dirt 4-stroke that had the shim and bucket, you sure there is no way change shims without removing the cams.
