Hi, new to this group! Any help would be really appreciated. I have a 1977 XS400 and can't seem to figure out why the spark plugs keeping getting carbon fouled after 10 minutes of riding. Any help would be great!

    If it's carbon fouling, not oil fouling, you're running rich. First easy thing to check- how are your air filters? Does the bike run well otherwise? Did this come on all of a sudden or not?
