yes but you did the compression test today and the compression is not the same in each cylinder that COULD signify a leaking valve
( or rings getting bad on one cylinder)
although it's fairly normal to have the compression not exactly the same, it is something to take notice of.... and one thing that can cause that is the valve lash being too tight on one side.... if you set them last week and ran it good sense then..... it could be that they got tight again in that amount of time..... head gasket seating in or something like it could cause that. where you live I would be running wider valve lash
because of the extreme heat you get in the summer months.
( in other words you could hear the valves) if your machine is nice and quiet I would suspect a tight valve....
However , your no dummy and you know your bike well, I just thought I'ed toss that out for ya !
have a good one !
