    It's the new year and we have a lot to look forward to in 2016! The site will be overhauled to keep up with the demand for new features, mobile compatibility, and security issues. Change is hard, but in this case necessary, and we hope the transition goes smoothly and makes for an even stronger community.

    If your resolution for the new year was like mine to de-clutter and organize, and you have boxes of CB750 parts you don't know what to do with, consider listing them in our Classifieds Section. It's simple and free. Register today if you're not already a member.

    Thank you to everyone who has helped to make this community great. Hopefully we have many more great years ahead. Happy New Year to you all!

    Check out Johnny's (Stabler) 1971 Amen Savior CB750 build! It turned out great! He bought the frame on Ebay in 2009 and had it delivered in early 2010. The project took about three years to complete. He started by getting a CB750K5 motor with the later '77-'78 carbs and a MAC exhaust. He had the handlebars custom made to his specifications out of stainless tubing. Stabler made a stainless steel bracket to mount the NOS (New Old Stock) Sears auxiliary lights and he also made the sissy bar from stainless round bar. The bike has a Harley Narrow Glide front end with a 21" wheel up front and an 18" wheel in the rear. The seat is an old C&G that Stabler reupholstered himself. The tank is an old '70s GME and the rear fender is a simple bobbed flat fender. The paint job was done by Mats Kroon.

    See the build from start to finish.

    Problem with Carbs maybe ?

    I do know, it has to be points/condensor, coil/wires, plugs or the bike wiring, the only things that will cause no spark on mating cylinder pairs.
