I have some photos for you, but I still don't know how to load them on the NSR site, despite being a member for 5 years! One day I will get someone to show me. Send me an email (danwilliams@greeneking.co.uk) and I'll send them to you. Roy Chester362 also has a HRC PGM, his is for unleaded race fuel, whereas I don't actually know what mine is except that it adds power...
Inked numbers on my HRC are in black (sorry I said earlier they were blue). CI-6050.5. I also have a what I think is a JHA PGM, but it makes little more power than a standard, the JHA number is CI6068.3
Cheers
Dan
