For whatever reason it took me over 2 years to find the Rickman Facebook group, but I have joined up and there is a wealth of knowledge there a mile deep. I have tons of pictures but never really had anyone I could ask questions to and get real time responses.
It just so happens there is a chap on there that is making new CR frames/swing arms, but over in the UK. I have messaged him to get the particulars. I would imagine the lead time is long, so I will be able to do a "pay as you go" type deal hopefully. I also need to make sure I can register it in the US for street use, though it would make a killer AHRMA Formula 750 bike.
My Borrani connection is checking with the factory about drilling the rims special for my hubs as they would have done for the original kits back in the day. I still need to do some measuring to make sure the wider rims will work with everything, especially front tire clearance relative to the fender/forks, and for clearance to the sprocket out back.
I am working on sourcing all the parts to rebuild the AP Lockheed brakes, which includes two calipers and one master cylinder. Looking at $500 or so just in parts to refurb all that. Fortunately I have an AP adjustable ratio master to use up front I got for a song at a swap meet, just needs a new cap. The masters are $350 new so that lightens the blow a bit.
