I didn’t think there would be anything wrong with painting mine black with high temp paint. So I did, and it’s holding up well. The kart had some rust on the outside of the pipe and I didn’t like that, pipe was off, paint went on. Then I found out from some experienced karters at a practice day that having an unpainted pipe helps to see if the mixture is too lean or rich. While that does make sense I don’t regret painting it. I’ve painted all the two stroke pipes on my dirt bikes, adjusted jetting etc, and did that by other means that the pipe color. Although I’m sure some have found using the pipe as a tool for that works, I haven’t. But I learn new stuff all the time from forums like this, and would appreciate input on this.
I don’t race my kart, didn’t plan on it, plus didn’t think a painted pipe would disqualify me from racing if I wanted to. I think that’s a strange policy, can’t race with a painted pipe, please explain further if that’s the case.
