Just found this site and am in need of some help if available. I just got a 95 650L from a buddy who hasen't ridden her in over 4 years...she just sat there. anyways i got it and cleaned out the stock carb, petcock, jets, and tank but when I try to start her she does a number of things. Here is a list for those more mechanically minded than I, when running, she will only run on full to 3/4 choke and then not for more than 5 minutes when trying to start if i turn the key off and on again it will turn over at least once which it won't do it will just keep cranking. while trying to start it she will occasionally backfire with a vengence. my frustration is at it's height right now, i have two batteries luckily and when one goes dead i pull out the other and put the dead one on the charger. don't know what to do, so any advice will be greatly appreciated.
