It's hard to diagnose over the internet, but the first few things that come to mind are:

1. Ignition issues...chances are, the last guy chased a problem, replaced a few parts and gave up. Coils, rarely go bad, but the connections do. (Corrosion, disassembly damage, etc.) Make sure that all of the connections are clean, including where the coil mounts to the frame. Rust or other Oxidation will/can alter the performance.

2. Fuel....The in tank Petcock Screen could be clogged, Lacquer deposits in the Carb, Jets, Float Height, etc.

3. Over Oiling of the Air Filter.....

Good Luck.

One of the major causes of a high rpm miss is a rich condition. Just a few questions I like to ask are 1) do you know what your jetting is? 2) Is the lid on the the air box?
Just a quick way to check can be to remove the air box lid if it's still on. I can promise you that this Will allow it to breathe enough to lean the Topend if it's a lil on the rich side. Let us know guy.
