2003 ZL 600 EFI goes 0-50 mph no problem but will not accelerate pass that or if it does it takes for ever. Any ideas what the problem is?

I'm not doubting you but how do you know the servo is working? Are the cables set properly? Another issue I have heard although not on that model is the baffle/shield coming loose inside the silencer causing it to loose power.
