A couple weeks ago I poured some STP carburetor cleaner into my bike’s gas tank because it sat all winter long. The next day I tried to start it up and it wouldn’t turn over. I tried again a few days later and it started up and rode just fine, but now it’s idling ridiculously high compared to what it was (idles at 3500 RPM once warmed up now). I talked to a technician and he told me that I probably just put too much of the carburetor cleaner in for the small size of a motorcycle’s gas tank, and that was causing it to run lean which is why it’s idling high. His theory made sense but I ran the tank out yesterday and filled it up again, and it’s still doing it. Should I be worried or will this process tank time, a few tankfulls or what? Or is there another explanation?
