hey guys, i just picked up a 90 kawi 650sx, and its my 1st standup. looks like its in decent condition. the guy couldn't get it running due to the stator being off the flywheel. I reinstalled the stator, and it turns over nicely. I did a compression check and the #1 is 160lbs and #2 is 155lbs. when i tried to start her, she started to backfire, and make some popping noises. I did get it started for about 10 secs, holding the choke open all the way with the throttle. he claims he was playing with the carb. does anyone have the factory manual that they can send me? or point me in the direction of how to get one? or any ideas why she pops? thanks i'll post pics in a little bit.
