WG you seem to be the authority on carbs around here so I'm hoping you can help. I have a 81 KZ750 H2 all stock. I replaced the old carbs with a new set and have not been able to get the bike to run proper since. The old carbs are no good, cracked casing(don't ask). The new ones came off a 1983 KZ750F1 LTD, engraving on the body says Keihin #1739 UK18 CV34. There are a few differences, the new ones have the T connections for breather tubes and my old ones did not. I don't think that should be much of an issue. The thing that boggles me is on my old set I had 3 jets, pilot needle/main and one other. The new set only has the pilot and needle/main. The spot for the other jet looks like it is plugged and there is no threading to put a jet in there.
The bike runs and idles rich and is only getting about 15-20mpg. I took down the jet & needle sizes but left the info at the shop. Anyway, If you have any thoughts on what jet sizes I should be using I would definately appreciate the help. That missing 3rd jet that apparently is not used on the new carb is really throwing me for a loop.
If anyone else has seen this setup on a CV34 please chime in.
