Re-jet required?

[Guest]

If I put in a new airfilter with a higher level of airflow, will I need to re Jet my carbs? if so, how involved is rejetting?

If you put on aftermarket individual air filters, you will probobly have to re-jet. You could buy bigger main jets, and maybe new pilot jets, or you could just buy a dyno-jet stage 1 kit for your carbs.

Does it run any different with the new filter? You can probably get away without rejetting. If it runs the same, id say leave it, if and difference, than consider jets.

Best way to tell if you need to re-jet is to see how it runs, as above post says. But also its easy to check your plugs for proper color. They'll get very light tan or white-ish if they are running too lean. Over the long haul that's hard on your motor.

If its just a different air filter for your stock air-box or set-up you'll probably be O.K.

The color can throw you. Say you run the bike wide open then drive it back to the barn to check it, the plugs will not look right. You need to run it up, then shut it off. Bad thing to do with a turbo.... Better way is to look at the heat line. It acts more like a memory device and records your peak temperature, so even if you have to drive the bike to the barn at a slower speed, the heat line will remain unchanged.

We are talking mains, wide open throttle testing....
