For folks with fuel concerns on their oil samples, you might consider that if the Spyder has a remapped ignition, that could be a source.
Greater power output requires more fuel to make the power, even running rich of peak to keep valves, pistons, etc from becoming damaged.
Also, a poorly working or failed fuel tank purge system could introduce raw excess fuel.
Ambient temps also require fuel adjustments to obtain proper trims. In higher heat areas, the greater intake temp will cause a rich condition and significant power loss. Simply another possibility.
Not saying that is the absolute reason why, just areas of concern I would have.
