Duneman,
I don't agree. With a closed throttle slide there's no way for air to flow through the carb and suck more fuel through the main jet. I guess a crankcase air leak *could* cause a blip in RPMs but fuel in the the crankcase would be quickly burned and the bike would return to idle RPMs.
My condidtion was sustained WFO with a slack throttle feeling. I pulled my carb again this weekend and closely examined the needle and found two nick marks. The only thing that I can imagine could have caused these were very small pebbles stuck between the needle and main jet circuit, thus holding the slide open.
