Finally running like a dream. 1978 CB750F
« on: May 17, 2025, 05:27:30 PM »
Spent the last 5 years rebuilding in my free time and dialing her in. Finally, everything works the way it should, and now every time I go out for a ride, I come back with a pain in all four of my cheeks  ;D

Shout out to all the contributors/old timers who make it possible for inquisitive minds like mine, who haven't ever seen the inside of an engine before, to take on projects like this.

Nice job!

See SOHC4shop.com for info about the gadgets I make for these bikes.

When I was doing part time construction many years back I worked with an old carpenter named Mike, his favorite saying was "A job well done is a well done job".  Certainly applies with your bike.  Nice work........

Looks good Hammerspace! I like the small fairing. I am thinking about putting one on my 76F model. Are you using stock bars?

Thanks everyone!

@GaJet - Bars aren't stock, they're the "superbike bars". The fairing is the Emgo Venom Mark II fairing.
