carbs
« on: November 20, 2013, 08:54:12 AM »
Is there a site or book, that will show me my carbs, and  break them down. I would like to know what are  low speed jets , emulsion tubes etc. I know nothing about them at this time.

Please don't try to explain it to me in the forum. I would like a reference in front of me. If I can't get my bike sorted, it's gone.

the CB750 shop manual, plus a Clymer or Haynes repair manual to go along with it are great.

Contact member Hondaman...he wrote a tell all book on the CB750 and has a great section on the carbs from a mechanics restoration perspective. I think you can find it in the For Sale section of this board. A must for the 750 buff...

YouTube can be your friend too. Just search CB750 and you will find all kinds of video how-to's.

Yes! Youtube vids have saved my bacon more than a few times. But you have to learn to weed out the hacks from the people that actually know what they're talking about.

A big +1 on Hondaman's book. You may also want to try here http://www.helminc.com/helm/search_service_owner.asp?Style=helm&class%5F2=AHC
They do reprints of the old Honda service manuals. I just got one for my new to me 1984 Aspencade and it's very high quality.
