    Carb Question

    I just rebuilt my carbs and while I was taking apart the right one and removing the main jet, needle jet, etc. there was a gray scum clogging the screen and pretty much everything. The left carb was fine. I talked to a guy at work and he said that this is from the Ethonol E10 that is sold in this area. Is he right? Have any of you guys seen this? Anyway to prevent it? Any idea why it would be in one carb and not the other?

    I'm thinking a picture of this scum would be a good idea. Don't think I've seen gray before.
    One carb only is odd, too. Has the bike sat a lot?

      Maybe river water from the Monongahela got in there.

        Should have taken a pic but didn't think of it at the time. It was just a gray scum...hard for me to describe it any other way.

        As for sitting...I use it for work 6 days a week, 9 months out of the year. Riding to work is a mix of city and highway riding and the engine always reaches full temp. In the winter its ridden any good day we have. The problem that made me redo the carbs was sporadic sluggishness when it would hit about 40mph, the gas mileage dropped to about 50mpg from about 60 or so, and the idle would climb to about 2K when it would warm up.

          Haven't tried swiming with her yet. I try to stick to the bridges.
