Thanks a lot Adam. The Cheney sure is a rarity. I'm going to use the trick GYT RT1 engine that was intended for my #1 Hindall. That frame now goes onto the reserve bench while I do the Cheney and the Ducati Hindall. I managed to get another ACK head, this one for the DT1 engine that's going back into the DT1 from Hell. Don't worry about the Yam wheels right now, they've been put on the backburner because I'm going to use Rickman hubs on both bikes. I'm looking for a DT2MX/RT2MX pipe though, if you or anyone else has got one.
