Motorcycle Repair: changing jets, slip on exhaust pipes, carb adjustments

Question
do we need to rejet carburetor after installing after market cobra slip on exhaust pipes?

Answer
Randy, A lot of the pipes that are aftermarket require a jet change. Check the mfg suggested jetting guide that comes with the pipes it may have some helpful ideas. These pipes depending on the style actually lessen the back pressure on the exhaust and may need more fuel to run correctly. Depending on the ruability factor Ive had to even lean a Honda Shadow out from stock to make it run good. If you have a dyno close by with a oxygen sensor after the pipes are changed it may tell you which way to go with the jetting and carb adjustments.
