Hello group. I have refurbished my 77 cr125 but no carb kit exists for the factory keihin unit from that year. I understand it was basically a one year or so only model.
Re-Mx had a mikuni vm28 IIRC that would work on a 77 model but their website has been down for over a year and they won't answer email. Mikuni would work but would need some jetting changes according to re-mx. .
I need a carb, new or used that will work. Recommendations welcome. I just want it to run. It is completely refurbished. I will post a photo in a day or so. I'm not going to compete on it or anything of the sort. Thanks as usual.
I will buy if someone has one for sale.
The trick I've found that works for RE-MX.com is to use Chrome to shop/order, if you use Edge or Firefox you'll never get it to work.
Also, most guys were putting 32mm Mikuni's on their 1974/75's so not sure why you want a 28mm.
The below link would get you close on jetting:

There are a few 32's on ebay, below is a link to one:
Mikuni 32mm Round Slide Carburetor | eBay
Would a Keihin PWK fit?
Thank you so much. I'm not a much of a mechanic. I can do the most simple projects. That's about it. I got 28 idea from Re-Mx. I appreciate you helping me with this.

I usually order my jets from Jets-R-Us, below is the link. I don't use aftermarket or no name jets, only original Mikuni or Keihin.

Hi. That one was sold. I assume this is the same thing. Mikuni VM round slide 32mm . This one has left hand idle adjust. I notice there are some Mikuni knockoffs. This is for a vintage show bike, not for riding. I just want it to run. So will the knockoff work? Looks like ebay has sold a lot of them. I don't mind ponying up for the mikuni. I've spent a lot on it already. Thanks for your help.

Call Sudco. They can set you up with a carb that will get you going or at least in the ball park. I would suggest the 32mm, but the 30MM will make it easier to start but less top end. Check with them if your stock manifold will work. If not, source a Suzuki TM 250 as it will support the Mikuni.

Typically that would be fantastic advice - Chad there was very proficient in getting things pre-jetted based on all the pertinent info--- however Sudco closed their doors at least 7-8 months ago unfortunately. A REAL kick in the nuts for us Vintage racers
Strange, they still have a web presence. I did notice a customer post from Dec 2024. Sounds like they are no longer in the game.
They were still answering the phone as late as June 24 , although they were just selling off old existing stock . I called to see if Chad was hooking up with another supplier, as he was a wealth of info , but he was already gone. From what I understand,their issue was caused by Keihin cutting them off .
