Now see that is the problem with those d**ned 4 strokes, just to many parts! :lol:  :roll:  :shock:  :lol:  :roll:  :shock:  :roll:  :wink:

Thanks everyone. I'll do the couple of checks listed here before I go inside. I found out these bikes take special tools just to set the valves. 4 strokes arrggg. I'll take reed valves over this.

John:
Sorry, I can't keep silent...

If the oil-seals on the valve steerings are worn engine oil seaps through. The symptoms are typically blue smoke when it's started after standing for a while. Run the engine hot, let it stand for 15 min and start it. This problem won't show up as poor compression. The fix are new valve seals.

You should (don't know the english terms here) also wear in the valves in the seats (rotate with carborundum). This does address poor compression.

If there is constant blue smoke, it's more likely the piston rings.

I had the chance to look it over some more this week end and it's about as bad as it can get. I started it cold and the blue smoke rolled out the pipe. I then opened the oil fill and I believe I could take a compression check there. So I'm in for the long haul or overhaul as it might be called.

Thanks for the info on checking things.
