My 99 suzuki intruder 800 is all the sudden backfiring at low to mid rpms.it wont idle without choke. i changed the plugs and added some seafoam to the gas. the last time i rode it it ran like a champ anyone have any ideas?
The key words in your question ( The last time I road it )
The problem is the slow speed jets in the carbs are plunged up This jet controls the idle circuit and the slow speed circuit of the carb In order to do it right you will need to have a pro clean the carbs. This is not a do it your self project !

Hi Lcyr.
Any changes you make to the exhaust system will alter the sound the bike produces. The more you cut baffles,and open up the exhaust, the louder it will get. What you do alter to a greater extent,is the state of tune of the motorcycle. Any changes to exhaust or inlet plumbing will require a retune of the engine to suit the modifications. This can be subtle to dramatic. Opening up exhausts can often rob low end power where exhaust port scavaging is relient on some back pressure for maximum effect.
Best to work directly with an engine tuner to do the mods that are known you can get away with, or buy aftermarket prebuilt pipes that have a known previously tested state of tune. Nothing worse than doing something, that then costs money to put back the way it was on finding out it didnt work as well as was hoped.. Hope this has helped you steer your custom mods a little. I can say with certainty, that I have ventured to do what you are doing many times in the past, and it has always cost me more money in tuning and... and well more parts :) Cheers
