It does sound like an ignition timing problem, but could also be a breathing issue, air flow in or exhaust flow out could be restricted i.e.:dirty air filter, excessive carbon build up in exhaust pipe from burning too much oil or rich fuel mixture.
possibly and more likely some junk got into your fuel system and partially plugged up the main jet in the carb, -or has the needle on the slide been moved? The little circlip at the top of the needle, if it has one.
1.Replace the spark plug, check gap, check spark, it should be bright blue and fat.
2. check the fuel filter, if no filter check the carb for dirt.

I would have it checked out. I know that it has limitors on it but it shouldn't be half throttle. It should rev as soon as you start twisting the trottle.

It sounds like your bike has been sitting in storage for an extended period of time (a year or more) - and the carburetors are plugged up. If this is the case, they will need to be completely disassembled and cleaned out.
If it hasn't been sitting (and the carbs aren't plugged up) then check that all of the normal tune-up items have been performed, especially valve adjustment, oil and filters, spark plugs, etc. If this fails to produce positive results, perform a compression check on the engine. Each cylinder must be able to produce at least 140 psi of compression in order to run and idle properly.
