Someone was asking not long ago whether they required a valve adjustment. Well here is some info that might help you decide. My GTS has 31 000km. No important service has been done to this machine. Just oil\filterchanges at too long intervals. The spark plugs were changed just before I picked her up in NOV 2000.(I really don't know why the previous owner even did this). Well I just did a compression test. I don't want anyone to get surprised or shocked over the results, because I have seen worse. #1=180psi #2=30psi #3=80psi #4=90psi.This what happens when things are neglected & taken for granted. Wonderful isn't it?More to come. Peter Piazza
