I want to replace the stock pipes with an aftermarket set. Do I need to have any work done to the carburetor? If so, would a jet kit solve it as well as improve proformance?

Talk to the person selling you the pipes, they should know if the airflow is going to have any effect on your performance and what you need to do to make it run right. If he doesn't, shop elsewhere.

It depends on which set of pipes you are fitting. Some pipes are designed such that they will work with a stock setup, and others are not. Some pipes are designed to be a cost effective replacement for crumbling, expensive stock items whereas others aim to improve gas flow and scavenging In the case of the latter you would definitely need to rejet, but in either case it would be a good idea to get a Dynojet kit fitted and set up on a rolling road.

Stretch got you covered. New pipes mean a new carb profile. You can't afford to have the bike run lean if you got better pipes. You could keep the same carb, just get a better jet. I had the carb and pipes replaced as a unit. S&S carb, and SE II's for exhaust. Got it all dialed in at the shop. No trouble with idle or git go. Runs like a top.

When you change the pipes the company who makes them (Cobra, Vance & Hines...etc.) have correct re-jetting kits for whatever bike it is, and if you have duel carbs (or more) I suggest you have them synced. Also, make sure you install new exhaust gaskets when you do it. Usually changing pipes will result in some performance increase, but not always, as some bikes are already at peak performance balance with their stock system. I presume you also want some sound, which more open exhaust will give. In my personal case I added Vance & Hines to my 1100 Honda Shadow Spirit and it did improve power, smoothness and great sound, rejetted of course and carbs synced.

any stock bike made in the last 10 years will perform better & run cooler if you re jet or re map to a richer air/fuel ratio. even with the stock pipes .but usually even more so with less restrictive after market pipes.

would be best to change out the air filter to a high flow 1, and yea u will need a rejet. it's the slow speed needle that needs changed. the main jet is only used in 100% throttle apps.....like u'll ever go there.

depends on what changes the new pipes create in the air flow... insufficient data... why do people start ripping apart a good machine without the first clue of what they are doing? geeeez 50 years with bikes and I have never understood it, and it don't change, generation after generation...

I can make it simple, if ur bike backfires when you decelerate after you installed the pipes, yes, you have to change both the pilot and main jets, if it DON'T backfire, you don't have too

Most likely you'll need to rejet.
