John, No problem we are all here to help and like I said it's been along time since I have personally gotten my hand dirty on these bikes. I remember mostly how they work and the different designs of each model. Search the classified part of this site and you may also want to enter what you want in ...

John,
If I was you I would forget about the CA engine and concentrate on getting either a complete CB engine or all the CB inters for the CB cases. It would probably be less expensive to get the complete engine even if you had to rebuild it. Cliff

John, what do you mean by a bare head? Does it have the valves, cam and lifters, or is it empty? The CA crank as I said earlier is a 360 degree and would work with the CB cases as far as I know but than you would have to have a Type 2 cam for the head to make it work. Cliff

Gordon,
The CR71 was chain drive or at least the 59' was, I know because I had one. It's been quite a while but the engine was basically the same as the CB's that came out later. The upper motor mount was different due to the frames being different. Cliff

John, I'm a little confused on what you are asking for with the info you have given. You start off saying you have a CB with a CL engine and later you give a Engine # of a CA. The CA's as far as I know are all 360 degree and do not have a tach drive off the left side of the cam and have one carb. So...

Yes.... Cliff

you may have a stuck or partially stuck ring(s). I have had this happen twice in the past. I added about 8 oz of Marvel Mystery Oil to the fuel tank and 8 oz to the crankcase. In both cases it freed up the rings and the smoking stopped. This was on two different bikes and I may have just gotten luck...
