My son and I have just bought a 250 Orion and a 250 Atomic Kuda. Both are very good bikes and run really well. Except for my son's Orion. When ever he opens up the throttle and the revs get higher it starts miss firing. We've replaced the CDI, mucked around with the fuel mixture and replaced the spark plug. It got better but it still missing up the top end a little bit. Does any one have any ideas as to what the cause of this could be? I'm pretty sure it's electrical...
