When I got my quad dynotuned it was 85* out. Now this weekend it's only gonna be around 65* for a high all weekend I was wondering how much fuel I should add in the wot fuel cells

it shouldnt make any difference with the amount of fuel you use

usually colder weather creates leaner running motor so yes he should go a bit richer but not sure how much

Dont mess with it, it will compensate for temp changes.

pretty sure these fi bikes are simple as they get, i doubt the fuel adjust it self, it doesnt have an O2sensor. the only thing i can see self adjust is the timing advance that goes off of the air intake sensor when the intake temps get real hot.
