I know there are plenty of threads on this topic already but I have tried most of the things mention and I still can't seem to fix the issue. Heres the deal, I just bought the bike and it wouldn't idle when I bought it, but I could tell it ran perfect when at 3000+ RPMs. I cleaned out the pilot jet because it was completely clogged and now it will run at a lower RPM but still dies if I completely let off the throttle. Also, when I am decellerating it pops ALOT, I'm not sure how to fix this. I'm almost positive the jets are stock, I know that the needle is. Be gentle on me, I'm new to being my own mechanic. If someone could give me a list of things to check from top to bottom I would very much appreciate it. P.S. The previous owner did the blue wire mod and it also has a power core IV on it, but I think thats all that is different from stock.
