Heading to Baja later this month with my 2013 YZ450. We are going to have some long days and I am wondering if it is possible to tune the bike for more fuel efficiency? If so, can somebody make a recommendation for mapping?
I have the Acerbis 2.2 gallon tank and plan on carrying some fuel with me but would like to maximize the range of the bike if possible. I am running 15/48 gearing and we generally are staying away from the most technical trails.
Engine and exhaust are stock with the exception of a Lexx spark arrestor end cap. Should I pull the spark arrestor and go with the larger tip vs the 'quiet' tip? Not worried about power, more concerned with fuel efficiency.
