How to fix a motorcycle that putts when u hit the gas?

You really didn't give any info about the bike. You really need to look at basics. Start with clean high octane fuel. Clean injectors or carb. What kind of rpm are you showing at idle? Do adjustments need to be made. Even though it is probably nutty and neurotic to some I change wires and plugs about every year regardless of use. It is overkill I know. Check you cables are they functioning properly. How about the air cleaner. How clean is the air filter. Have you modified the exhaust?
