Is it for certain that the engine has combustion in all four cylinders?
Has water mist been sprayed on exhaust header pipes after first starting cold engine and allowing about 15 seconds to heat the headers? Spray should immediately vaporize and sizzle off all four headers. Water running down a header indicates failure of combustion inside the cylinder.
Good Luck!

pulls hard at 4000 on up horrible off the line --- am thinking this indicates the bike is performing with less than normal low end power.
If not already done, would assure automatic advancer unit isn't stuck in forward position.
Possibly a carb issue at lower rpm, such as sync, or pilot adjustment, or pilot circuit.
But would first rule out any non-carb problems.
Good Luck!
