How did you measure compression? Hold throttle wide open when cranking? Lots of folks forget to do this and the compression readings will be bogus.

If the bike runs decently, it is hard to believe compression is down in the 60s. Next thing to do is check valve clearances using a set of metric feeler gauges... makes shim selection easier. If you don't have a manual, I have a "how-to" on our website that has pics.
Wiredgeorge, do you have how to with pics on changing shims?
If so would you share it with me, as I am about to embark into uncharted territory this weekend.
