I bought a 750 vulcan and the previous owner played with the carbureator settings. I replaced the dead battery and can get the bike started but only with the choke on fully. It is the only way the bike will remain running. Any tips on how to set the carb would be appreciated.

If you are really stapped on cash napa auto parts has some heavy duty rubber spray. Just spray a thin layer over both sides of the diaphragm to repair any holes/tears and let dry overnight. My diaphragm was going to cost over $110 for one. It will still have full function and be even stronger than stock!

You can but the slide with the diaphram separately as a single unit. They used to cost about $50.00 US, the choke cable fitting will also be available separately as well. To outright buy the carburetor you will not only making a tremendous amount of work for yourself but you will be spending I would guess no less than $200.00 US. They actually have diaphram kits you can buy from after market suppliers for even less money than the dealer and they are OEM Keihin parts.

Bought a used 1996 kawasaki vulcan 750 with no choke cable. got a new cable and can't find where it goes. I where see where the end of the cable goes but don't see a bracket where it has to go...

Ignore all these idiots. The engine does not need to be remove. He must own a dealership. Simply remove the large air tubes to the right carb and move the left up out of the way. The bracket is on the left side, then feed the cable to the right between the carbs, a bit tricky. You'll see the choke lever on the back right of the carbs. insert in the cable holder. You have to bend the cable up to slip into the holder, the back down to lock it in. Before all of this, attach to the hand lever first.
