Jet sizes after ear shave

This next week I will be performing the ear shave! Only thing left to order is the jets, I was thinking going with the 40s and 140 but saw a write-up on it where the guy used 42s, and 142s. I don't care about gas mileage as it still beats my v6 truck easily. I'd imagine there would be added power to the engine with the increased air and fuel mixture. Im concerned that there would be too much fuel and cause of problem or that the bike would over heat more or something... What u think?

Bike won't over heat with too much fuel. If the Air/Fuel mixture is proper, the engine will run like it should. 142/42 seems to be a common jet combo for ear shave. I plan to do this soon myself.

I only understand what I don't understand.

I found my 140/40 setup was (a tad) too lean here at sea level, and am moving to 142/42.
