    Would a cylinder head swap between a 81 - 83 xj650 seca turbo work on a maxim or am i just looking for trouble?

    Don't you have a thread about a turbo swap already, or am I thinking of someone else?

    OK. So I'm going to go with no then. It will physically fit, but I believe that the combustion chamber is different, and part of how Yamaha lowered compression for the turbo. The cams are also different.

    I am getting desperate in my search for a new head to rebuild. 82 xj650s seem to be rare unless its a seca turbo. However there are more xj750's for sale. I know they use the same head gasket and bolts but would an 81-83 xj750 head fit an 82 xj650?
