My 2010 300 Nambotin has been fouling plugs quite often for the last couple of years. I thought I had it fixed when I found my crankcase gasket was causing my engine to suck in tranny oil.i fixed that but this week for the first ride of the season it has fouled two plugs already. I've been using the same oil and buy the same gas from the same station. Could I have a bad jug of premix oil? I use Amsoil Saber 80:1 and Shell V Power gas. The bike will run all day with now problems it's just that first start up for the day that it fouls!
