Pod filters jetting

fighterDaz
Hi guys, haven't been on for a while. I have bit the bullet and decided to turn my 82 cb750 into a hard tail chop/bobber. Does anyone now the correct carb jetting for pod air filters and straight through exhaust? Daz. UK

For these DOHC CV carbs there are two answers.

Deuces wild says to start by replacing the 68's with 75's and the 102's with 110's.  You'll likely need to experiment with jetting a little bit after that point depending on your engine.

cb750c says to not use pods with the stock carbs because they'll never run as well as the stock airbox.  If you want to run pods you should buy different carbs.

I haven't tried to run pods (yet), just passing on info.

If you do decide to do it, I found this resource that might be helpful for the fine tuning:

Need to combine it with some more info/tips from here: http://home.everestkc.net/malsin/Motorcycle/carb/mc_carb_theory_101.htm

Let us know how it goes.

Also - pics of your new hardtail build?

You cannot just change main jets.

The idle jets will need attention  and the slide needle position needs work.

Good luck! I have never heard of anyone successfully running Pods with Honda CV carbs, but go for it. You might be the one to make it work.
