Topic: CB360 jet size

[cb650]

Anyone know what is stock for a 76?

Assuming that your carbs are using the 745B or 747B setup, original jet sizes are as follows according to the factory manual:

Main (Primary) #68
Main (Secondary) #68
Air Jet (Primary) #150
Air Jet (Secondary) #50
Slow Jet #35
Slow Air Jet #85
Float Height 18.5mm (0.75 in).

Thats what I was finding.   My main seems to be a 102.  Sounds way to big.

[Bill Vaughan]

Yeah, that seems beefy for this bike even if the intake/exhaust were opened up to any degree.  They tend to run on the rich side in stock form.

Thanks.     Have some smaller jet that will fit I'll see what they do.

That sounds like 250 jetting. All my 360's (4) had 68/98 mains stock

Might be a typo.  My book says the same thing.  Cant imagine someone going from 68 to 102.

Yeah, I've got the same crappy Clymer book.
 I've got the Honda one somewhere but cant find it at present.

It's got to be a typo in the factory manual.  I checked mine tonight and they're 98's, too.
