[QUOTE="Serf27, post: 209854, member: 4478"] It has been fixed! The idle still needs some tuning to be perfect, but the bike is no longer dying! I went over to the bike shop today telling them it was still dying with the choke on. They looked at it. Shot cleaner through it and said it was all clear. Then the guy noticed the throttle slide(I think that's the name) was sitting too low in the carb and the throttle screw was already bottomed out. He came to the conclusion the throttle screw was the wrong one and I got a longer one and he adjusted it to where the slide moved up a little bit more. Here's the old vs new screw.

Before the gap between the slide and carb was almost non existent. [URL='http://s173.photobucket.com/user/Serafin13/media/C251F69A-4D85-438F-A05C-087976AB12AC_zpsxphhdeep.jpg.html'][IMG]http://i173.photobucket.com/albums/w62/Serafin13/C251F69A-4D85-438F-A05C-087976AB12AC_zpsxphhdeep.jpg[/IMG][/URL] I put it on the bike, started up and was idling without the choke!! I hope it is the end of this issue. I was able to ride it and come to a stop with no dying. Thanks everyone! With this good news comes bad news. My brake lever snapped yesterday and I put a new one on, right after the new one, the cable snapped.
