So I'm trying to improve my kayfun v4. Sadly the vaping trend is more airflow Than the limited MTL air draw the kayfun v4 offers.
I don't want to retire it, I need to make it more airy, more open draw, more of a lung hitter. I order a 4S kit from FT, but the openings were the same size. So I used a drill bit to bore out the center of the screw post and a smaller bit to open 2 of the tiny holes on the hex part of the pole. It did open it up some, but still no where near up to par for lung hit tanks. I'm not sure how much more it could really be drilled again, kind of running out of sidewall of the post.
Are there any threads or links to kayfun v4 modifications people can share? I'd appreciate it.
