Hello,
new member to site - just picked up an 82 gs750 - one of the carb bodies has a broken post to hold the float. like to get a new carb body but not sure if the carbs are original.

i have looked and looked and other than "mikuni", not seeing anything stamped on the body to id it as to what model # it is -

any clue to where the model # is stamped??

thanks in advance, looking forward to getting this biek back on the road

Welcome to the forum.

Both ‘82 750 models, the T and the E, had the same carbs as shown on this chart found on BikeCliffs Website. Which model do you have? Sorry, I don’t know if or where any identifiers may be stamped on the carbs. But if you show us some pics, I can compare them to mine.

I know there are some good YouTube videos on broken float post repair. I also think I remember seeing a tutorial floating around somewhere as well.

A few helpful links in my signature especially for new guys. Start with the top 10. BikeCliffs website is a treasure trove of info and helpful how-tos. If you’re interested in posting full size pics to the forum, I have info on that too, using Imgur as a pic hosting site. Like this:

Go ahead and add your bike year and model to a signature, then you’ll never have to type then info (or forget to type that info) when you post questions. Go to Settings at the top right of any page, signature links will then be on the left side.

Tip on using this site’s search function: In order to get any meaningful results you must use Advanced and you after typing your key word(s) you must change the search criteria to Titles Only.

If the stamping is still visible, it will be near the top of the carb body, just below the flange for the diaphragm. I have seen them on either side of the carb, but it WILL be on the side. Just a permanent ink stamping, nothing embossed or engraved.

The carbs are Mikuni BS32's. Specific details matter though and ideally you should have the part number specific to your bike. The pressed in air jets can't be changed for example. Check the carb sticky post and check out the details.
