Bike just back from Gowanloch Ducati where Mike was helping me track down why the front and rear cylinders were up-to 200 degrees Celsius different in temp!

Mike did his checks, tuned the carbs and the engine sounds sooooo sweet! BUT, even with over 30 years experience Mike (nor any other mechanic!) was not able to see the two HIDDEN issues lurking...

AND...the temperature issue remained but WHAT could it be???

What next??

Hook up my Tuning tool and see what it says!

I don't know what AFR means, but it looks like the V (rear) never varied in spite of RPMS. No advance? reversed polarity?

Q Which cylinder had lowest temperature? You did not say?
