Thread: Starting Issue

  1. #1

    Default Starting Issue

    The other day I was riding my 2004 FZ1 and on the lower RPMs it felt like it wasn't running on all 4. I decided (very stupidly) to tear into the carbs and clean them up. When I put it all back together, I tried to start it and it ran for about half a second, then died, tried again and there was a big pop from backfire and then wouldn't ever start again. I don't believe I forgot to reconnect anything when putting it back together and this isn't my first time cleaning carbs either but first time on this bike. I don't know what the problem is now. It's not a lack of gas in the bowls either, they have gas in them.

    UPDATE: I can get it to run on one cylinder at WOT.

    Coil packs?, Spark Plugs? All connections are tight and carb boots are not cracked or brittle? Just a preliminary thought.
