Fxdx -01 Bigsucker and 2-1 exhaust.
Cv carb with N65C, lightweight spring and drilled to max.
Slow jet 46 main jet 195.

Checked and fixed manifold seals becous they leaked. Fixed a small leak in exhaust. Rebuild carb.

And the bike is still popping more then i want it to and sometimes sneezing through carb on slow speed when giving gas.
Got the ez-just 4turns out. Popping more the further i screw it in.

Removed and opened the carb about 20 times so far.

Could shimming the needle be the way to get rid of the popping?

About 30min on that plug. Front cylinder.

the jetting sounds right,,, the plug shows too much fuel and or oil...
I would go with a slightly heavier spring,, and a slide vac port drilled I size ove stock..
I believe the slide is moving too quickly,, allowing too much air to enter in most riding conditions..

I tried running that kind of setup and I had to jet it stupid rich to get it to not pop on decel, and then it would still do it in certain situations. I'm thinking that the high flow intakes and exhausts are more suited to EFI than to carbs.
