2000 harley fatboy will not stay running shuts off

Whenever I have a question about an aftermarket part - I contact the manufacturer, they are very helpful, but to answer your question, In general, if u get the correct part for your model bike, it should mount the same as the OEM part you;re replacing

SOURCE: Mikuni jetting

If it's the Sreamin' Eagle Mikuni, it should come jetted close enough to take your bike to someone with an exhaust gas analyzer. That's the best way to get your card jetted correctly with the extensive amount of changes that you have made on this bike. I would advise that you take the bike to someone that has a dynometer that is equipped with an EGA and have the run the bike up. I would not want the mixture to exceed 14:1 at any time and preferrably run about 13.5:1. It's a bit on the rich side but it will help keep your engine running cooler. I've installed the carbs before but I cannot remember what jets they had in them. Sorry. Good Luck.

Testimonial: "I appreciate your quick response to my question. Unfortunately,I live on an island and I don't have much choices."

There's hot and there's too hot. Heat is one of the factors that shorten the life of an engine, especially an air cooled engine. You bike is equipped with the oil jets that help cool the pistons. If it were my bike, I'd take the bike to a known good high performance shop that had a dynometer, an exhaust gas analyzer, and a good mechanic that knew what he was doing with both the bike and the dyno. I'd have them run the bike up through the RPM range and check the fuel-air mixture ratio at various rpm levels. If the bike is running too lean, it'll run hot. Lean is mean but too lean is bad. The mechanic may can richen the mixture up just a bit, say from 14.2:1 to 13.7:1 and reduce the heat while maintaining the performance you want. It's worth a try.

Good luck

SOURCE: backfiring and popping on deceleration

Aftermarket pipes tend to lower back pressure, this will cause the fuel/air mix to lean out and result in the "popping" you hear---Backfiring, is extremely rare these days with electronic ignitions and the high reliability of engines. Real backfiring means the engine is not properly timed and the fuel/air mix is getting a spark and ignition at the wrong time (when the intake valve is open). Real backfiring is actually the bike "spitting up" in a sense, backwards through the carburetor or intake.You can check for exhaust leaks up around the cylinder heads by putting on some gloves and covering the exhaust tips momentarily. I have seen exhaust leaks that will make the popping worse by allowing air to be sucked in during deceleration...Hope this helps.

With aftermarket pipes they will almost always run on the lean side due to the reduction in back pressure...Retuning the carb is required. If you have an aftermarket air intake, this will also effect it.
