Re: Idles but wont rev up

There are many reasons your bike is doing this, but an almost new (560 miles) bike should have no problems like that unless a rat ate your wires, It's most likely related to the carb or a vacuum leak and not something in the ignition system. If you feel concerned about that then give everything a careful going over and look at it. You may also have some gummy deposits or dirt in the little screen over the fuel intake tube in the gas tank from sitting for years unused.
Do you have a free flow of fuel from the petcock if you set it to prime and disconnect it from the carb, or open the drain screw on the bottom of the carb with the petcock in prime? Maybe your fuel flow is restricted.
Also try and run it with the gas cap off just to make sure you don't have a gas cap vent problem causing a vacuum in the tank.
Both of those ideas may be far-fetched but are real easy to rule out a fuel delivery problem.
