  1. Fouled plugs everytime I add gas

    Suzuki TL1000R & TL1000S Forum
    I have filled my 97' TLS up twice in the past week and as soon as i fill it up with premium gas, the bike runs like hell and fouls the plugs. What gives? I have never seen this before. Why would filling up the gas tank, all of a sudden cause the bike to run rich and foul plugs? Any ideas????
