Does any one have any suggestions as to what might be causing my 426 to foul plugs on a regular basis? Last year it ran great and never fouled a plug this year I have fouled about 10 plugs. I've changed the brand of gas I'm running but this has not helped. Also I've noticed that the bike wants to back fire and miss on occasion. I think it is a carb problem but I am open to any sugestions.
