I picked up a set of 32mm carbs from Davw. Just figured I would post up a couple bits that some of you may know. The 30 and 32mm inlet rubbers are the same they simply bore out the inside for the 32mm carbs, The needles were very different 30mm had n77q which were about 2mm shorter than the 32mm's n77s needles. The diaphrams and slides are interchangable as well.

I don't know what he cleaned them with but you could eat off the inside of the carbs. The outside looked like standard used carbs. Pleasantly surprised by the insides. Thanks Davw!

N77s needles are from an austrian L1 model according to the manual.. no idea where the N77q needles originate from

The n77q came from my 1994 Japanese spec bike. I have no reason to believe the are not OEM.
