I'm trying to get some bikes ready for craigslist when the weather warms up. I've got one that started with some starter fluid and 6 attempts or so. It started and died a few times after the starter fluid wore off, but then it started and went up to 5K or so. I turned down the idle screw on the carbs and it idled lower until it went up high again. Turned down the choke at that point. Since the choke worked as an accelerator of sorts, it told me that the choke ports are clean and working. After it warmed up, it would idle at a sensible 1.5K, which gave me the impression that I had the idle jets clean enough (I've torn these carbs apart more than once.)
So I rode it up and down the street a time or two, and the RPMs just seemed to keep climbing.Stopped to turn down the idle screw again. By the time I got it back to the garage it was at 1.5K. Made me relax. Then, for no reason, it just zoomed up to 2K. What would make a set of carbs just make the engine rev higher and lower by itself, with no input from me at all? Wondering if it was the carbs being out of sync, I put the manometer on it and found that #4 is weak and #3 is strong (1 and 2 pretty close together), but there's not much I can do about it due to the horrible inaccessibility of the adjustment screws (V30). Pretty much have to pull them off, turn the screws, put them back on, and check again. Not fun, but I would do it. Any point to that? Once they're clean and synched, I don't know what else there is. I should mention that I put new boots on the carbs, too, so I don't think it's leaky boots leaning the mixture, but I should do the starter fluid test anyway. Any thoughts? Sticky vacuum slides maybe? -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
