Where to get Main and Slow jets

So after cleaning my carbs and reassembling them I still have a some hesitation. On a recommendation from others with the same sort of set up (K&N filter, Vance & Hines 2 into 2 exhaust) I want to go up one size in both the Main and Slow jets.

Does any one have any sources on where to get them?

Factory settings are no1 and no3 carb is a 110 and the no2 and no4 carb is a 112 for the main jets and 38 for the slow jets all around. Never ordered Jets before do they go up in sizes of +1 or +2

Thanks for the help

 

Call Factory Pro. Tell the exactly what the set up is on your bike, air filter, muffler, etc... They will build you a custom kit or probably have on in stock ready to go. When I tuned the carbs on the Hawk GT I used to have, their expertise was invaluable.
