    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!

    Weak power to coil. New coil may be no good as well. Not impossible. Flip them and see if problem moves. No enough dwell (too wide a gap) on one point
