Hey everyone, I've recently undertaken a project which is an '85 GSX250 (twin cylinder, BS30SS CV type carbs) that I started working on a month or so ago. After lots of work I have finally reached a point where the engine should be running. I can get it firing and idling but only on one cylinder. I have cleaned out the carbs to the best of my ability (I have no way of reaching the transition ports at the butterfly or the middle of the choke tubes, etc) but I definitely CAN smell fuel coming from the exhaust of the non firing cylinder. There is lots of spark and I have even tried a spare coil (have a spare parts GSX250 as well) to the same end. Even though I can smell fuel from that exhaust; after pulling the plug it is dry. I even threw in a brand new plug, ran the bike and pulled it, still looks brand new and shiny as when I put it in. Still sparking like a champion too. I have no idea what could be left to check and if I need to take it to a shop so that they can check for flow or air leaks or something then I will, but as a project bike I'd really like to try and nut it out myself, any ideas on where I can start troubleshooting or what the problem may be?
