Okay so I bought this bike sometime in the beginning of the year. It didn't want to start when I first got it so I took the carb off and cleaned it, went through the jets with a bobby pin and what not, made it start but had to be on choke if I wanted to run it without it cutting off when I let off the gas, so I took it apart again and cleaned it but it did not help at all so I decided just to run it on choke. It will not cruise at a steady speed because it's "jumpy" with the throttle in one position like its bogging so I just blip it unless I'm constantly increasing speed. Fast forward six months I'm still riding it with the choke on, backpopping every time I let off the throttle. I've also tried messing with the mixture knob but does nothing but help. I have posted this before but none of the answers I got worked and I'm completely fed up with it. Any help?? I only paid $1200 for it.
