I am having trouble with my stock 04 Busa with 4200 miles on it, I was coming home after a high speed pass on the interstate and it started missing out (dead miss like a fouled plug) at anything below 4000 rpm's, After replacing the plugs it is still difficult to start and it seems worse, If you hold the bike at 5000 rpm's or below it's like I'm turning the kill switch on and off, Above 5000 it runs great, At an idle you have to flash the throttle to keep it running.. I did notice that there is a place for a hose in front bottom of the air box that has nothing hooked to it ??
Thanks for any helpful advice you guys might have.
