I was trying to start up my 99 SV today and had a flame shoot out of the carb when I opened the throttle. The tank is off and being cleaned at the moment, so I've been feeding it fuel through a bottle directly through the line to the carbs(since there is no fuel pump on it at the moment). Before, it would start up fine like this. This time there was white smoke coming out of the exhaust. I'm pretty sure this is the result of some rain water getting in the airbox when the cover blew off the bike. Since there is smoke coming out, im guessing the cylinder is going through the combustion cycle but for some reason it's not starting. So my question is, is the flame shooting out the carb bad? I was thinking it may be a badly seated valve (they looked dirty too). Also, I still haven't gotten it to start through all this. Any tips? Thanks guys!
