Carb kit

[dna9656]

Anyone got a source for carb overhaul (rebuild) kits?

I have a set of 1985 carbs, are they compatible with my 83.5? Is so I'd like to overhaul THEM and install them on the 83, keeping downtime at a minimum.

The 83 body has the vacuum port above the main body while all later have the port below the main body. They all use the same boost sensor but the difference in port locations means the 83 uses a "special" TCI for that port location. The 83 used a few different jets than the later bikes but I don't think that is critical as it was a mild detune and few of us feel we are "starving" for more horsepower..

 

Look here for the carb part differences...

Trying to order carb parts is nutty... Yamaha wants to treat them as "special"... But Mikuni made two versions, the side draft (look for the 80-84 stock BS34 Mikuni carbs) and our down draft BDS34 carbs. Most parts for each are interchangeable. At most you need the two different rubber plugs for each jet block, jet block gasket, o-ring for the main nozzle between the jet block and the carb body. The fuel bowl 0-ring "should" be fine but check it's not collapsed, it obviously needs to stand proud of the surface to provide the compression seal. No carb kit for the Venture but I understand they do make one for the same year V-Max... jets are probably different but body and main parts are the same. I highly recommend a fully torn down carb body gets an acid ultra-sonic bath... those internal ports are impossible to clean properly by any soak.

I have a ultra sonic cleaner I use for jewelry, not sure it's big enough for the carb, www.sportsmansguide.com might have an affordable one. what kind of solvent should be used? Does anyone have any idea about the measurements for the O rings? Metric o rings are pretty scarce in the PAC NW. Granger sells 10ft. lengths you super glue together. A 2mm X 10' goes for $3.08.

Seems wise to me to have the stuff ON HAND before you start

I have done many other motorcycle carbs with hot water, simple green and mild dish soap in the Ultra Sonic cleaner.

 

A good cleaning can take as many as 6 hours of intermittent run. I change the location in the ultra sonic cleaner frequently- duringc cleaining

So no overhaul/re-build kits....???

My bike is a XVZ12DKC2, you'll find that M/N in the 1984 Year model parts book but NOT in the 83 book. So I have a 83.5 so to speak.

I got rebuild kits for my 87 off eBay and they worked perfectly

This is the one I got from Canada

In my case I needed to get new needles as well and I had to get them from the dealer.. They come with the needle and the spring as well as the little "O" ring and washer.. Cost me about $8 here in Canada so I'm going to guess half that your side of the border..
