G’day John, I like your projects, I have a few the same on my plate, that have stalled but reading this thread I will have to pull my finger out and get back on it, have a 1975 Rickman CR750 duel seat with mags and twin discs on front, I bought it in 2005 it had a 1000 cc engine but serious oil leaks from sleeves between 1/2 and 3/4 I sold that engine, as I built an RC 970 for my chopper back in the day and had a similar problem. The new engine was going to be 900 but I just bought an old drag bike and it’s full house 73mm 1055cc and that’s my new Rickman engine. Also have a Santee softail chopper project and just sold my Santee hard tail and bought an Amen Savior project on the go. I finished my second Sandcast a couple of years back happy with them. I am in Oz following with interest cheers Tom
