well bs34s use those jets so theyre definetly not froma 76. measure center to center on the carbs because my xs400 used the same carbs but differnt spacing of course.

also the bs38s that 76 up to 79, used pilot jets that are very similar you can tell the difference by looking at the bottom of the jet. the bs34 will have a small opening and the 38 a large opening at the bottom

A picture of the carb would be more helpful. Mikes has pictures of the carbs used on the 650. The carb guide a good read.

I meant pics of the OP's carbs. With those we may be able to ID them.
On the pilot jets the 70-75 BS38 and the 80-84 BS34 used a BS30/96 type jet. The 76-79 BS38 carbs used a VM22/210, these jets also fit most VM round slide carbs as well as the TM flat slides.
The N151.067 may look like it's right but I don't think it is. If it was right I think it would have been mentioned before.

No 650 carb ever used the N151.067 type pilot. Basically, it's a no-hole version of the BS30/96 type. What you may be seeing is a no-hole version of the VM22/210 type. Yamaha did install them in some of their late '70s CV carbs. You'll need to closely inspect the jet to see which end the metering orifice is on .....
