Background
The ST died on me the other night while on the freeway. Had high RPMs, and suddenly lost power. Coasted to the shoulder, and eventually managed to get her started back up. Limped home by keeping the needle under 55 mph. (I noticed the power starting to go if I attempted to accelerate, so I obeyed all traffic laws.)
I was convinced my shoddy "winterizing" had gummed the carbs, but I ended up talking to a mechanic who told me it sounded like a fuel line issue. Ended up buying a new fuel filter, since that seemed like a cheap start for diagnosis. Also, why not, right? The old one had over 5 years on it...
The fix is in
Ended up finding a couple posts from other riders here with the same issue, and found the bypass workaround. I completed the bypass, and pulled the whole petcock out of there. I took the bike for a spin, and it seems to be working great! Decided to pull the petcock apart after I got back home, and think I figured out the cause of the problem...
That's bad, right?
Looks like I have a diaphragm replacement in my future...
(Unless enough people here who have never replaced theirs after the bypass convince me I don't need to!)
