Ok, I was just basing it off of the articles I read about lean vs rich:
The ones with stars by them are what has been noticeably going for a while, so I figured it was a too lean scenario.
either way the plugs are getting replaced, so I can go from there and see why happens
Too Lean
When a carburetor is running lean, the fuel-to-air ratio is off because the carburetor is delivering too much air. Typical symptoms of a lean mixture are:- Backfiring as the throttle is closed (primarily during coast-downs) ****
- Lurching acceleration
- White or light gray spark plugs
- Requiring excessive amounts of choke to run/start ****
- White or light gray muffler end pipes
- Bluing (on chrome systems) of the exhaust header down-pipes****

FWIW you can also get back firing if you are too rich.

Get some new plugs and see what they tell you.

tried tuning it out last night, and wound up running the battery down so it is on a trickle charge now.
i just reset it back to where it was when I pulled it, and then I will re adjust from there.
The point where here it had optimal throttle response and took longer to die out, was only 650rpm. The service manual says 1000-1050. Any recommendations on why that would be so substantially lower?

Reason i have been in such a rush trying to get done is I just had a new baby, and my bike is my only way to get out to see them an hour away.
If getting a new carb is the play here, what would you recommend? Stick with the CV, or go to something like a super e? Please keep in mind I am not that experienced mechanically, so I need to make sure I am able to work on it myself.

Here is the break down
CV best mileage
Mikuni - best street carb
Super E - easiest to work on and best race carb

The super e bolts directly to the manifold rather than the way the CV just kinda hangs in there.
