278 Posted September 21, 2010 Report Posted September 21, 2010 hey guys just want to know what you guys think about getting a 392 big bore ported? or leave it as it is? cheers Porting is never a bad idea if you want more power. It will wake your shee up quite a bit. Depending on the cylinders they may already have a port from the manufacture, like I believe the cub cylinders and such have. Quote
J-Madd Posted September 21, 2010 Report Posted September 21, 2010 There is almost always room for improvement on the ports in the 392 Cub. The 421 and 465 are pretty good right out of the box, though (especially the 421.) Quote
