Hey guys, I need a few suggestions on where I need to start I just completed daves carb mods on my 2002 650L. Needle shimed, 55slow, 158main jets, drilled slide, removed air snorkle, the baffle removed from stock muffler, smog stuff removed. I fired up the bike, which ran really smooth for about 20 to 25 seconds then it just cuts off while idleing. Im not sure what could be causing this, but I suspect it may be flooding out. Once it cut off so I loosened the drain plug at the bottom of the carb, and some gas ran out of the drain tube. Does this mean the bike flooded. I did remove the side pannel thinking more air to the air filter would make the bike run better, but it still cut off while idleing after 20 seconds. I did replace the fuel mixture screw with a new fuel mixture screw made by the company "ziptie". I had to do this b/c the guy who owned the bike before me had broken off the mixture screw. Any amount I adjust the fuel mixture screw the bike still cuts out.
