Question Diaphragm confusion

Hi. Can anybody clear up this anomaly.
I'm trying to order a pair of diaphragms from JBM industries.
I've requested K-67s, which are the ones recommended for the VN750.
The invoice from JBM states that K-67s will fit CVK 36 carbs, but I believe the VN 750 has CVK 34 carbs.
Have I misunderstood something?

Just because you're paranoid, it doesn't mean that they are NOT all out to get you.

Yes, the VN750 (and the VN700) both use the CVK34 carb. Perhaps JBM has a typo in their listing ? perhaps the CVK34 and 36 share the same diaphragm ? I agree it is confusing. Maybe contact JBM and ask them would be my best suggestion.

One can never have too many alternative forms of transport.

K-67 diaphragms are correct. The same info appears many times in other posts but this is probably the most recent thread...Read post #7 https://www.vn750.com/forum/showthread.php?t=57249

yeah, the K-67 diaphragms are definitely correct.

The way I understand it (I could be wrong though) the k-67 has to do with the size and style of the diaphragm. While the '34 in cvk34 has to do with the size of the air intake. portion of the carb.

......I'd rather wake up in the middle of nowhere then in any city on earth.

Thumbs up Reassured

Thanks for your input. It's K67s then.

BTW Texas, I love your strap line. I'm rapidly heading in the same direction.
