The bike is a 04 ZX10R with 1,500 miles on it, the bike was a animal.Parked it one day and the next day right from the start you could tell something was wrong the bike it started to run like crap and got worse and worse you could not even pull a wheel on it, before if you where in 6th doing 40 mph you could get on it and it would take off, now 40 in 3rd and the bike just stumbles and can't get out of it's own way. You could hear the motor sounding like it can't breath or it is being held back (40 miles to a full tank of gas)So we try a few things so we take the exhaust from the servo motor back off to look at the flapper and it appears to be working, so we take it for a ride with the pipe off and the bike is back to normal, we put another pipe on it from another Zx10R and the bike is running great Has anyone ever heard of a muffler going bad? (we did put the orignal one back on and it ran like crap again) If you shake it you don't hear anything moving.
