1977 cb750f----915ci build

Yesterday I picked up my next project. I got a 1977 750K and 1973 750 K engine, both complete for $200. The plan is to build a second high performance engine for my 1977 F2 (836) rather than starting a another bike.


I am looking for opinions on different configurations for the build. I am thinking about using my extra set of F2 cases with the 77K head and barrels.


* Cycle X 915 pistons and sleeves
* undercut trans
* lighten/balanced crank with Super rods
* complete head work
-stage 4 head port
-CB750 5mm valve conversion kit (34mm intake/28mm exhaust valves, guides, seals, springs, and Ti retainers
* all new bearings and chains
* M3 racing cam chain tensioner
* lightened rockers
* Megacycle 125-75 cam
* All the machine work will be done by APE
* The head work will be done by JMR


I already have so much invested in the cb I figured I would just build a second engine with a bit more kick. I want it to be a bit of a sleeper and get close to 100hp.


This will be done as funds become available so I can stay married. ;D I got the K engine tore down last night and all looks good inside.
Thanks for any replies and opinions!
