Jay Marmont Map ?

5 posts in this topic

Hello all-I just purchased a 2011 yz450. The question I have.is abount the Jay Marmont map. Has anyone had problems, such as running hot (lean)? I thought I read in the owners manual that adjacent settings should not be more than 3 increments away, ie if the center box is a +3 the surrounding boxes should be within +0 or +6. Please excuse me if I'm wrong, I just do not want to destroy this bike's motor.

Thanks for the input.

Marmont map is probably the best map out there for mx. It's not as on/off at low rpms and makes really good aggresive power across the board.
