31K Carbs

[stuboy]

How do I check if my RD350LC has the 31K carbs I was told it has ?
If It has should they be jetted as if they were on a YPVS of jetted as the normal carbs for my bike should be ?
What is a good starting point for my carb settings it is
Stage 1 tuned
Has Microns
Foam Filters
6mm Reed Block Spacers
Boost Bottle (assuming I can get it to seal if not standard link pipe will go back on!!)

LC/YPVS carbs have ID marks stamped on the bodies which can be seen in this photo (just above the 2T inlet pipe)



They will have 31K-00 (I think) if they are 31K carbs.
One carb will also have a vacuum take off for the YPVS fuel system which if fitted to a 4L0 MUST be blanked off.

They are 31k carbs. Where is the pipe that has to be blanked off ?
There appears to be two breather pipes on each carb(one half way up and one on the bottom of the bowl).
