hey i just bought a LRD full dual exhaust for my 2003 banshee right now my mods are just a single 35mm trinity stage IV carb kit and k&n filter with outerwear it seems to be running rich right now but i aint sure on it the plugs are black and have alittle carbon on it so i think im runing rich because the plugs dont look white at all am i right so my question is what size jets should i run in my single 35mm keihin carb with my new LRD pipes

 

Although I have no experience with the single carb set up, it dose sound like you are running rich.... Are you running an air box with a lid??? How dose the bike run right now? I would buy some plugs and some smaller jets, rejet and do a plug check....

 

i run with my stock lid on but it has a 3' by 4' hole cut in the lid it runs good down on low to mid but it just doesnt get up to speed when i have it pinned so thats another reason i think it is rich i dont want to rejet it now since my pipes are getting here in a week i think im going to put my pipes on with the jets i got in now with new plugs and run it for alittle bit and see if the jetting does better and leans it out more but not to lean then check my plugs and igo from there does this sound like a good idea if anyone knows what size jets to run let me know i dont want to end up to lean and blow my engine
