No use for these anymore, $650 shipped. Carbs only. As far as I know, they work on oil cooled GSXRs only.
No idea, the carbs do have the necessary adapters to run filters though. Those were not included in original purchase, and I might have a set of velocity stacks somewhere that I could toss in too. I had new BMC filters too, but many years of just sitting, and it seems I either sold them or lost them.
