Hey Guys,

Everyone was so nice to help me with my suspension issue, I'm hoping to go 2/2.

BIKE: 2014 Yamaha YZ450F

Does anyone know of a good fuel mapping to install in the bike to make it more suited for woods/trail riding? Its a bit of a weapon right now. I'm a large rider @ 260lbs.

Thanks to the VitalMX family!

You'll be surprised how much more controllable the bike is with +1 tooth on the counter sprocket (start here - it's cheapest and the least hassle) and 1-2 teeth down on the rear if it needs further taming. Your 450F will pull different gearing (higher) all day long no problem.

Don't forget the option of adding a tad more slack to the throttle cable, too (YZ450Fs have quick adjust cables, too - so you're in luck!). Makes the bike more tolerant of rider control mistakes.
