My 02 TBA is cutting out at highway speeds. This started in the fall and suddenly the plugs started fouling which they had not done before. Today I took it out for a test ride after doing the following things: Took out little gas filter and put in an inline. Gas tank is venting well. New plugs. New jets (too small actually). Float height is good. New battery. K&N air filters are clean. The problem still exists. I can red line it in the lower gears with no problem but once I hit 4th and try to open it up the problem starts. It also seems to be heat related. Could it be electrical? I'M hoping someone could help me figure this out. I'll be back on this site at 10PM tonight to answer any questions. Thank you.
