Check your fuel pressure. If it's low, then check fuel strainer on pump for restriction.

Hi, it could be a wheel bearing, a bad motor mount, if it's front wheel drive it could even be an axle rubbing on the frame (hince a bad motor mount), etc but it's hard to say without hearing it myself. But should have a good idea of where the problem is now and fix it.

Hope this helps.

Sounds like it's running lean. Almost everything you mentioned here would cause a carb equipped bike to run lean and cough and sputter and stall. Since you bike is fuel injected, I cannot help you. If it were mine, I'd take it to someplace that could put it on a dynometer with an exhaust gas analyzer. They may recommend the installation of a PowerCommander. Your local dealer may can change the fuel map.

im sure the valves and compression are good. as for changing pipes, the computer will adjust for it to a certain point. bringing everything back to stock will probably increase your power. if you want to keep the pipes and fuel pack, i would buy an after market ignition module as well

check your primary coil if it is ok the problem is your cdi unit try to replaced it with good one.
