Okay, so I just went to do a run through on the shee gearing up for a trip in two weeks. All checked out good, except when I did a WOT plug check I came up with a yellow plug in the left cylinder and a slightly less but still yellow plug in the right cylinder. Mods in sig, but also running 100% Trick 114. Heard this could be a side effect of running a leaded race fuel, but also read on PS where a guy was told that it meant he was burning coolant. Bike does not appear to be losing coolant (evap in combustion chamber). Looking for some input before pulling head, or testing cooling system for hydrocarbons.

Different gases will burn different colors but also of course could be like you said burning coolant. I think VP has specific directions on their site how to read plugs when you run their fuel, maybe there is a site that does the same for the gas you run.
