@damien
Yes these CR29 carbs will work just fine with pods or velocity stacks. My initial jetting was a little rich.
I’d suggest with pods to go with 110 / 62 / yy7 needles / 240 air jet. Start there then fine tune to fit your needs. Every bike jetting is a hair different.

So. Are we saying that these carbs are good to go and will work fine with POD filters or velocity stacks? I have a 1980 CB650 Cafe racer that has the standard mechanical slide carbs. It runs Pod filters and is ok, but I have tried a complete rebuild, rejetting etc but it’s still not right. They were is a bad way as they had been stood for over 10 years, and really need replacing. Anyway, Thanks for any feedback you can give. Cheers.

So with the 81 cb650c having different carb spacing, how’d you get the intake boots on?

I have an 81 cb650c with these carbs on it, I ordered everything through dime city and had a little issue in carb spacing but they drop shipped a new set out directly from the supplier in Cali.

Has anyone tried putting the Cr 29 on the 1982 CB 650 Sc SOHC ” Nighthawk ” what parts are needed.

Yeah, curious what size spigot for 81′ Cb650? Also I have the C model 650 with the teardrop tank. Wondering if that’s helps or hurts the petcock clearance issue…

Can you recommend a good website where I can buy jets and needles? Can’t find any good site that has them al 🙁

Would you happen to know what kind of spigots you would need for a 81′ Cb650 or should I just assume it’ll face the same problem interfering with the petcock.

@wayne
Re-read the post again. I think you missed a few things I noted.
You want to buy keihin crs29 carbs with the spigots I mention in the post. Yes you have to space them out but it’s easy and you can do it yourself. It’s pretty easy to set it all up and get them working. Go with the jetting I recommend and it’ll get you in the ballpark then you can fine tune.

hi ed, did you get these to fit straight off the shelf or did you have to get them spaced to suit the inlet tubes on the 650 head, if you got them off the shelf whats the keihin part number please ?, cheers

I can’t use shorter spigots because the carb body will then hit the petcock

Wonder why the spigots are so long. Seems like the carbs could be closer to the intake boot which would make for more room for the filters.

I agree, all our old bike should be running these. Only problem is $$$$$.
