Well......
Power loss starting at 7000 and continuing up until redline???
Power loss from 7000 to a certain rpm and then pulls normally till redline??


Wouldn't hurt to check these anyways.....

Dirty/old air filter
Spark plugs/Ignition system (bad coil/wires/plugs)
Fuel mix for cleaning carb/injectors (gum in carb/injectors/system - reducing fuel flow)
