I have a 2000 Busa that fouled (I think) a spark plug about 600 miles ago I put new plugs in and it done it again yesterday. The first time it did it I had about 31,000 miles on the motorcycle and about 15,000 on the plugs so I thought it was just time. But I have only gone about 600 miles and now again. I pulled the plugs last night and they are all somewhat sooty. It looks to be running rich. I have a power commander, header, air box mod, BMC air filter and pare valve mod but these have been in play for 15,000 miles. What do I need to look for? could my power commander have taken a crap?
