Have an 82' KZ750 LTD and a 79 KZ650J. The KZ650 has some excellent parts but someone had torn down the upper motor and not put it back together. I want to canabalize the 650 to get the 750 road worthy. The carbs on the 750 are flooding pretty bad and leak. The 650 came with a set of Mikuni carbs. I can't identify them though. They look like the Mikuni VM vintage carb series but the tall part of the carb has horizontal ridges.

If posible I would like to identify the Mikuni carbs. The bore on the carbs is smaller then the bore on the engine (both 650 and 750). Does anyone know where I could get a reducer? I assume that's what they used to connect the carbs to the 650. If I can't ID the Mikuni's I'll just rebuild the factory 750 carbs.

Has to be a browser issue then. I changed the spelling in one word since the original post. Any other postings are a mistake.

The bolt hole location IS the same, those carbs will go on the 750 motor with 650 intake manifolds. I'm doing the exact thing to my 750LTD.

I'm not absolutely sure if the airbox boots ON THE AIRBOX end are the same between 650 and 750, but luckily I have both Gabe's KZ650 and my 750 in the shop and I will be able to report next week.

You will have to run a KZ650 right switch housing with 2 throttle cables. My bikes a 1980, so I only needed cables.

If I run into airbox issues, K&Ns here I come. Then jetting becomes a small issue. The plan is 650 carbs and 650 manifolds and airbox boots on the 750 airbox.

As far as jetting, the leader of the banned (A2 Rider and Zedx11) say the KZ650 jetting works well with an increase of pilot screw. I think she's running a MAC and pods. Her jetting was compensated for those items on the 650 engine. It is not stock jetting.
