I purchased a CB750A 2 summers ago, and last summer I put a custom draw through turbo kit on it, after a thousand miles of 10-15lbs of boost, I finally blew the head gaskets. I plan to rebuild the engine this summer with some upgrades and hoping for close to 100 Crank HP after the build. Hopefully documenting some of my work along the way.
I also own 2 other bikes, A KTM Duke 890 GP, and a Honda V65 Sabre, Hoping to fix up the Sabre and flip it this summer, flipped a KZ650 last summer and made some good money.
Cheers,
Kaleb
