Hi guys 1st post. I have an 07 drz400sm with 800 miles on it. I left for vacation 1 week ago and bike was running fine. I came back today and the battery was a little weak and would not let the bike start. I charged the battery and put some gas in it. It was almost out if not completely out of fuel. I tried starting it and nothing. I put the petcock to prime and it started only with the choke on. As soon as the choke is pushed either half way or all the way in it dies unless you have the throttle cracked about 1/4 way open. The bike idles high with the choke on. Also it seems to run fine when your riding unless you come to a stop or clutch it then it will die and will have to be choked to restart. The bike is completely stock. Should I be looking at getting a jet kit to fix possibly a clogged pilot jet. Thanks for any help.
