Please help!!!! I wash my busa on the averge bout once a week. Bout 6 months ago, I washed my bike, and rode it, and the enigne was lacking power, kinda like making a sputtering sound. I let it sit overnite, and rode it again, and it ran just fine. I juz washed it again yesterday, and it did the same thing. What could be going wrong here??? Any suggestions??
