Spitting back through the carb

I have a 05 electra gluide and it has spit back threw the carb since it was new. It does it when you are crusing at a steady speed. It has gotten worse and more frequent as it has gotten older any suggestions?

By the way I have upgraded to a big bore kit and a woods 6h cam.

I have a SE 44 mm carb that I ran on my evolution I could clean up and get a manifold for and put on

Yes it is the originall oem cv40. But it has ALWAYS done this. I know when a carb is lean they will spit back. Also when I went to the 95 kit I did re-jet it to a 195? Does that sound right?
What do think about the SE 44 I have?

If it is spitting back while steady cruise I would raise your needle .04-.05 or so. Maybe go up one size on slow jet and make sure your air fuel screw is adjusted properly. It is very popular to replace the stock needle with a N65C needle (early per acc. pump sportster needle) also check for intake leaks after a while the seals around the manifold could be leaking causing a lean issue. I put over 80,000 miles on my 04 carb and it still looked good when I pulled it apart so unless you have really high miles I would not worry about it being worn out. The 44 would probably be a good match for you cams.
