CB1100 valve adjustment purposely made rough ?

[bflint]

Was watching this video and the evaluator stated that Honda purposely adjusted Cb1100 valves to run rough.

Interesting assertion.

this video made me scratch my head more than once. I find this bike very , very smooth but will always wonder why the did the things they did.
BTW my bike does not tic, tic, tic when turned off and have never heard a single Tic ! absolutely glad the last big Air Cooled came along and i got to experience it .
one woman but Sooooo many bikes to enjoy and so little time :biker:

Mine tics like crazy, but it's the exhaust and not the cylinder fins cooling

No tics from my Staintune!

No tics from my Yoshimura. Or anything else.

The purported valve timing made out of sync between the various engine cylinders has been talked about quite frequently here as Honda engineers have detailed their approach to making the engine a bit rougher in order to make it "rumble" and give pleasant vibrations around 3k RPMs. Ironic since it's one of the smoothest motors most of us has ever experienced on a motorcycle, especially down low. It's certainly far smoother than my twin that could shake the fillings out of my teeth if lugged in the wrong gear. Also, the "tinking" and "pinging" the engine fins were supposedly designed to do during cooldown have never happened on mine after riding. It was always the headers and exhaust making the noises which was confirmed when I swapped the stock system for the full Yoshi system and now my bike makes absolutely no noises after a ride.

Speaking of ticking noises, do any of you hear ticking noises from the fuel injectors? Mine does this frequently upon start up, but the ticking stops quickly.

Yes, mine I also hear under heavy acceleration from a stop. Definitely the fuel injectors.
