So we have a few X-2's sitting in the garage and one of them is a nice clean model with few a/m parts. It came with a dual carb mani and with 38 bn's (not sbn's).

Anybody has experiance how would this behave if I swap the old bn for newer sbn's? I know they work really well on SJ's not sure whether this is applicable to the Kawi 650 banger.

Thank you

P.S. What kind of jetting would be ok? Factory SJ jetting would work? The x-2 has the basic engine bolt ons - pipe, waterbox, milled head...
