no compression on 1 side morning, i have a gs 500 1998 model and it not runnin on 1 side, i 1st swaped plugs, caps and coils, still the same. then found out there was no compression on 1 side, so then stripped engine down, replaced rings both sides head gasket and barrel gasket, we also turned head upside down and poured petrol on to check vales aren't stuck open, nothing so we think there ok, put back together still no compression on same side as before. can any tell me the next thing to try?? jamie |
