Heavy and IMO the ugliest side covers ever put on a motorcycle.Yes, that KZ750 uses BS38 carbs very similar to our 650 ones. I always liked that bike but I hear it's pretty heavy.

Taking a closer look at the one you removed, I don't see any air bleed holes. That means it's not a BS30/96 but probably it's no-hole version, the N151.067. This was commonly used in many CV carbs .....

The one you pulled looks like it may have been a size 47.5?
Yes no holes and yes 47.5, since this is a top (not down along side) mix float bowl I doubt top or bottom orifice matters in the pilot. except for ease of cleaning out crap. But those two wildly different pilot numbers in the parts diagram with no explanation seem mysterious.Taking a closer look at the one you removed, I don't see any air bleed holes.

Good question right? Was ok with the 47.5 but who knows, once the rest of the carb is back in spec. I'll follow up with "the rest of the story" later.Maybe the #30 size is a VM22/210 pilot? As I mentioned, the bowl looks like that type with the air being delivered to the top of the jet. Well, at least that type for 650 carbs. I don't know if Yamaha ever used the N151.067 type pilot jet in any of their carbs. It still doesn't make a lot of sense though, the sizes are very far apart. I mentioned having a PDF shop manual but it's no help. It gives no carb specs that I can find. What did you plan on putting back in there?
Finished putting some powder coated bits on the carbs and they are soon ready to be tested. Last thing to do is replumb the crankcase breather. Took the old anodized clutch perch off and had it powder coated satin black. New clutch assembly (new cable; one piece aluminum rod; 8 plate conversion; new clutch seal; Barnett springs) now operational. Might be warm enough this Tuesday to go out for a spin!

Anxious to fire it up! I’ll be sure to report.Yes, and do tell us how those "new" carbs work out.
