Strange question? I do not currently have an ST. I am considering a 1300. On my previous ST1100 I would check the valves without removing plastic except for the one plastic trim piece over the cam covers on each side. I showed this method at a few "Valvestoc" meetings at the house. We never had any valves that needed adjusting. I am wondering if a 1300 can also be checked without pulling all of the plastic that the manual probably calls for. I realize that an adjustment is a different matter.
