Q: Do I need to re-jet my carb after installing an aftermarket air filter?
I just replaced my stock filter with a new Twin-Air filter and was wondering if I need to make any jetting changes because of the swap?
A: Changing the Air Filter alone will not affect jetting
As long as you just replaced the filter and did not make any other modifications to the airbox or exhaust, the stock jetting will be just fine. The same goes for the K&N and No-Toil filters as well. Just swapping out the filter will not require any jetting changes.
