Rebuilt petcock today and now it stops the flow of gas when the bike isnt running just like it is supposed to. Maybe gas was trickling in to carbs and constantly overflowing. It seemed like the tank went empty too often! The insode if the tank was in great shape.

Got the Gunson Colortune in mail today, so doing another clean and setting air fuel with it tomorrow!

I took the gas tank off after running the bike for a few minutes to do a compression test, only to find that my petcock rebuild did not work. What a pisser. Looks like I picked the wrong week to stop sniffing glue...

The engine was warm, not super hot. Compression test results:
1 - 145
2 - 144
3 - 135
4 - 148
Question: Does this indicate that my valves are okay and I don't need to rip the valve cover off with the potential to compromise the gasket, or just that the cylinders have okay rings?

The cylinders were barely within the 10% range... Moving on to cleaning number way too many, then to the Gunson Colortune. Will be ordering a Carbtune next, then going back and forth to find unity.
