well my bike is a salvaged vehicle, '95 gsxr 750. My problem is that it fouls plugs ever 200 miles or so. My exhaust is pretty messed up, but I dont know if that has anything to do with it. i got the carbs completly readjusted 3 months or so ago, and it didnt help. I put some hotter plugs in it last week, but that didnt help, and as of recently, its worse. They're fouled every other time I ride. Any advice would be great.
