I picked these up a while back (pre E10 fuel) as just in case spares but I can’t see me using them anytime soon. They’ve just come back from Allens Performance where they had a full overhaul / service, invoice attached. £275.00 inc. UK p&p (collection welcome) EDIT: OE fitment to all UK supplied 900ss & 900 Superlight, including FE. (1991-98) Ready to install no faffing with ultrasonic baths, Allens set them up on their flow bench. When they serviced my other set of carbs it fired up first go and even the tickover needed no adjustment.
