So for some reason I had my head by my forks with the bike on and the fans came on and it seems my Lt side fan draws air in through the radiator, and the Rt blows out through the radiator. Would this make it turn one way easier than the other? Drawing air IN on the left could let it pull to the left, I suppose... but I'm having a hard time deciding what effect the increased drag caused by the fan's reversed direction of air flow on the Rt would have on turning.
Kinda weird about the fan direction tho... blade orientation attachment error, or wire-electron flow direction issue? Still a mystery.

It's to cancel out the mass torque effect and enable quicker turning at maximum cooling.

Besides that, I have NO idea!

Interesting observation. Perhaps find out for sure by holding a sheet of paper in front of each fan to find out which one sucks or blows, literally not figuratively. : )

I'm thinking that with the left one pulling cool air through the radiator, it would be better for the ECM and other electronic sensors mounted in the left pod than hot air blowing in the vicinity. Maybe?

Both my fans blow inward. Once I dropped an earplug and it fell off my tank bag down in between the pods, it got stuck in a vortex and flew side to side, I couldn't even catch it till the fans shut off and it fell to the ground.

i noticed that they draw air in from the front, but the left side seems to blow out under the headstock. it might be for the reason sparky suggested
