1980 GL1100 Gas in the crankcase. I just bought this bike two weeks ago and have done a lot of work to get it running. I´m getting really bad gas milage, but the bike runs well. I´m getting a lot of blow by from the crank case and gas in the oil and I think that´s where my problem is. The plugs look fine, so I´m wonfering how the gas is getting in the oil? Thanks for the help Dan S.
