Are they fouling out??? A little more info would be useful. One thing if it started doing this out of the blue is the choke could be broke and not shutting off complete. Please be a little more specific..

pics of the plugs and jetting settings, pilot jet, main jet, needle number, and clip location would be helpful

i had a leaking head gasket and the coolant seemed to burn out the plug. bike would run fine until all at once it would shut down, but only would shut down when the rpm got low. never just cut out when you were in the throttle. it was leaking slightly enough that the radiator would get low, but it was not often enough to suspect a bad leak. thought it was just pissing outta the over flow because its hot in florida.
