Motorcycle Repair: carb rejetting, bassani pipes, intermediate jet

Question
i have a 883 sportster. i am putting on a set of bassani pipes and am getting mixed info on which jets need to be changed. i live in high alt. (8150') do i just need a larger main jet, or should i make the slow jet change also. suggestions would be helpful.ride safe.

Answer
When you ride youa re mostly running on the intermediate jet, so that is the one to work on. Check your plugs. If they are white you are running lean. Black and you are running rich. Once you get the intermediate jet set then ride the bike hard for a few miles and then check the plugs again
Good luck and happy riding
