Have 2 of Russell's CCM motors fom those days. One has had the gearbox cut off it as it wouldn't hold 3rd gear. Studs were welded to the crankcase remaining and an A10 gearbox mounted. Also hae Ron's/Russells JAP motor.To increase it from the 500cc a large spacer is used under the barrell. When Ron was ill in 93 he wanted to get rid of all the motorbike stuff left and concentrate on restoring his first truck. I obtained the JAP in the "Arab" dirt track sidecar, a Lindsay Urquart centre hub steering road racer sidecar, used to house a CB750 and was raced at the International meet at Avalon, Ron blacked out down the back straight, crashed and laid on some old railway track as the back was a bit sore, found later in the week to have been fractured. Also got the CCM stuff as I had been in VMX for a while then and had aquired one. Unfortunately all the Wasp frames had been on sold after their seasons to finance new projects. I moved to Brisbane in 94 and swapped the 2 sidecars to the gentlemn who owned the bristish bikeshop in Beaudeset for some CCM gear. Also haven't seen them surface anywhere. Presently restored a 73 CCM, 2nd going in a 79 build when I have time/dollars and finally the sawn off is going in a Speedway frame to replicate the B50 experiment that BSA did in the early 70s. Still chat to Russ, tried to convince him to come back to VMX for Nats/HBBB, (he rode my maicos in Vic 90-93) but he is well and truly tied up in his speedway car jaunts and can't be tempted at the moment. Feel sorry for him first wife (now ex) burnt all his trophies/saches and photos in one of those loving bust ups, so he has little to show for the years when he was a top dog.
