happycheapskate Oct 20, 2009 I like this. What did you use? I've heard of using various brushes mounted on a drill. Some go kart builders told me to smooth the intake though.

1 low 64 Oct 20, 2009 Just used a carbide single cut bur and then dressed it with a 120 grit cartridge roll. I’ll probably end up smoothing it out later but wanted to try this to possibly aid in fuel atomization.
