His issue is NOT carbon build up. But your guess is as good as mine. What version crystal ball are you using? Mine just got an update and I still can't read it. He would be smarter to dump his fuel and spend $5 on fresh gas. Here is a video. Everyone likes videos. It's easy. Doesn't require research.

His video pretty much proves my point with the before and after pics at the end, although I'm not referring to carbon in the combustion chamber. If it will do that to a piston, it's doing the same to the injector tips and intake valves.
If Shell and other oil companies were already using those additives like you implied from the video, how did that combustion chamber get dirty in the first place?
head5, listen to the logic and science.
Bike runs fine when running temp is met. Book says to measure compression hot.
Bike does not dirty the injectors and clean up when warmed up.
Does that make sense yet? Not a dime out of pocket is back to high school or grammar school science I missed back then; is use it now and forever to explain your abstract or the title of this thread.
You're right about that. However, my thought behind this is that a fouled injector will not have a good spray pattern, and like we established earlier, fuel doesn't atomize as well in a cold engine, especially if the droplets are much bigger. Speaking hypothetically, with a hot intake manifold helping to vaporize that fuel, the condition wouldn't be as bad after the engine warmed up.
And, like I said, I could be completely wrong. But on something like a bike that will sit for extended periods, a fuel system cleaner is a good place to start.
lus1: Well said.
