Saga goes on. Decided to drain and clean the tank. Removed the level gauge. Between a powerball on the end of a pressure washer and a siphone hose - wow a lot of scale and crap came out of that tank. So much so that I could see daylight through a few spots in the bottom, LoL.
Sealed the bottom of the tank on the inside with a small brush taped to a long stick and a few tubes of JB weld mixed up.
Clean tank and no more leaks. After some more tuning using the software the Bike runs really well now, a roaring torque machine. So much power now that I am having other issues (clutch slip).
