Check what F5 has suggested.

Also...

Fuel starvation? Is the carb getting plenty of fuel? There's a gauze filter on the petrol tap inside the tank, remove/inspect/clean. Also check the fuel tank breather in the filler cap is working and isn't blocked, if no air's getting into the tank petrol won't flow out easily.

I assume air filter is clean?

Is the tail pipe clear? I've seen tail pipes blocked with wadding that's come loose. Bikes start but won't rev at high rpm as they can't flow the exhaust gas.

It's simple but can cause some strange effects!

Good luck.
