I was hoping it would be a while before I bothered everyone again, but had a bit of a development yesterday, and would like a few wiser minds than my own for a take.
I rode to work yesterday, it was pretty cool out here in MI. Even after the warmup, as I was pulling out noted a drop in power and then it picked up again. I chalked it up to cold bloodedness and carried on. It seemed fine. It was the ride home that became much more eventful. As I would leave a light, I noticed some light bucking, but it would clear and keep going. Finally, on a side street, it would just die with some throttle. I could restart it and it would idle, but giving it gas would just kill it. I switched to reserve a few times, even though the tank was nearly full. It's an '05 1300S, so no fuel pump.
Quick background - I rebuilt the carb and did the PAIR blockoff about three weeks ago. The carb rebuild isn't my first or even my 30th, and the bike ran downright excellent thereafter. Still, I'll recheck EVERYTHING today, vacuum lines, etc. The carb rebuild was pretty thorough, including a new diaphragm.
I have the stock vacuum petcock, which at this point, is fifteen years old (the bike, however, only has about 6K on the clock, so it sat a lot, hence the carb rebuild). Based on research here, my thinking is that could be the problem. At the very least, I'm thinking of replacing it anyway (or do the rebuild kit) as a preventative measure.
Is there anything else I should be checking? Going to tear into it today.
One other thing I found strange when I first got the bike - it would only run for about 10 seconds if the petcock was shut off (forgetting to turn it on). I would think there'd be enough in the bowl to run it longer than that. Not sure if it means anything, just pointing out.
And thanks so much (in advance).
