I used to run straight Seafoam in my bikes during winter service. But they were carbureted, so instead for the the fuel injectors, I use a Chevron product called Techron. That has always cleaned out my injectors well.I have heard of water misting to de-carbonize engines. An old FJRForum inmate (HaulinAshe) even recommended introducing pure Seafoam into the throttle body sync ports until the engine stalled. Don't know if that is something I would try...
