From what I understood, Glen simply ordered the parts with the Keihin part no. on the packets. Don't know if you can get all the different types of needle?
Give allens a call and see if they can order the needles from the part no.s.
I'll have to dig out the part no.s I wrote down at some point as I can't seem to get on to the tuning section via the links?
As Fontyyy pointed out, the parts with an HRC part no. are no longer available. Might be worth a try asking Allens if they can source them though?
