I have a 2004 Kickstart, and when I got it had some issues. Had a car air filter with sand inside it, missing parts, stuff like that. Cleaned the carb out, and I got a K&N filter and a White Brothers E2 exhaust. That's all I've done to it, and it's doesn't idle. It a 155 main and 48 pilot. I thought the pilot jet was to small so I 52 pilot, and now it idles on choke but not when the choke is off. I barely know how to take apart the carb. I don't know what to do any more and I don't wanna take it in because that's expensive.
