Its either the CDI as posted previously, or possibly a very badly clogged exhaust. To check CDI put a timing light on the bike, and rev the motor and see if the flash gets erratic at higher rpm.

In terms of needing different size jets, what you need to ask yourself is why would a PO fit the wrong size jet if the bike was running well?

If it is CDI problem, you will find cheap Chinese pit bike AC 5 pin CDI's will work on most bikes using an AC system.
