No, the P.O. rode this 75 for years, it fell into disrepair and it sat along with 5 other 750's that for one reason or another didn't run. He liked them but wasn't big on working on them or hiring it done. It was in the 75 frame when I bought his 6 750's. Later, I went back for a 78 Goldwing.
He said he always wondered why it was faster than his other 750's. It may have the K0 cam but not the carbs, head or cylinder. He also thought the crankcase looked different.
