Hey folks,
Been a while. I finally got around to syncing my carbs after syncing my friend's yamaha v-star cruiser. Man that was a simple machine to work on! No wonder he's a mac guy.
So I'm back on the Unix's of the Motorcycles, my katana. So, here's what's been going on. This is the carb from Arsenic's refurb, it's working great, and the only thing for me is I'm having trouble syncing the beast.
Couple of things. First, I made a manometer with 1/4 inch tubes, 2/4 cycle oil, plywood, with about six feet of tubing to attach to the bike. No problems. I also made a gas bottle out of an old bike water bottle, and a T nipple, to attach both of the gas lines to. I also did a bench sync, real crude, just looking and adjusting the screws while watching the end points of the arcs in the butterfly valves.
I apparently left the vaccuum line that attaches to the petcock off, because I have no idea where to put it.
So, I'm syncing the carbs, and I hit first the left most screw (If you're facing in the bike's direction). It seems to lower the high idle rate. Then I hit the middle one. That also seems to lower the idle rate, by a lot. I'm making progress! Then I hit the right one, and that one's not doing much of anything, and suddenly the bike's idle is fluxing like a mad horse on a static field.
I experimented a bit with the vaccuum hose, and felt the pulsing vaccuum on it, and when I blocked it up, the idle went up, and no matter what I did to the screws, it didn't make it move. It floated around 4000 rpm. I take my finger off, and then it drops down to almost below 1000 rpm before it conks out from being unsustainable.
So, I've done a lot of research, but NO WHERE have I found what to do with the vaccuum hose, the one that attaches to the petcock to the right most side of the carb.
Also, while "attempting" to use the carb sync tool, the vaccuum was so strong, it just sucked up the oil right into the carb. Any suggestions on making this easier to use? I'm using 6 feet of tubing! Per carburetor body! And it's a 1/4 inch internal diameter, I'd think it would have some give, right?
I could sure use some help.
