differences between trail & race porting?
I have a 2002 400 4x4 with a HSP speed kit + billet premium head and I want more power. I am going to get a pwk 39mm carb, HPD aluminum air box, and V force reeds. then this fall I was going to get a bubba port & .20 wiseco piston. I was just wondering if I could get the race port with the HSP pipe and clutch I already have (blue primary, white secondary in the # 2 holes, 45/40 secondary helix, T 15 weights I think ) I do mostly trail riding but also ride the dunes alot. how does the race porting do on slower rides ? any info on the differences between the two would be helpful??? thanks for the help folks
