dual 46mm on a 701 with a dry pipe

I believe that ed may be in error
if you follow this link then you will get the genuine pdf manual for a sbn carb

I have that manual in my toolbox. I have checked and rechecked and not all of the specs for popoff are the same. And I have checked every combo of n/s and spring. And I did it exactly the way the manual specified on stock 38mm carbs and my Full Spectrum carbs using a popoff guage that came from mikuni.:biggthumpup:

Springs will vary a little, but I have found that if you have a good needle and seat then the values will be close to what the manual states. I have noticed that the needle valve arm has to be not bent from its original state. This can cause the pop off pressure to vary by several pounds. I only bend the arm a little to get both carbs popping even.

I agree they are not always bang on
but they are not normally 20% out

Anyway not that it matters
how is the dry pipe jetting going
