My son will be doing some riding above 5000' elevation and according to the manual the main jet would need to be changed and some adjustments made.  However there is no indication in the manual describing what the change should be.  Can anyone offer some guidance?

Jetting requires leaning for elevation, so he will need at least one size smaller main jet.
