Whats the difference in these motors? and what classes run what motors? i just picked up yellowfin hpv with a 3 pipe on it. i plan on running hpv lite in the GLSS next year. is this the right one?

The motor is the same in all the classes. The only difference is the pipes (and the carburetor in the HPV 1 class). The 1 is for the cadets, 2 for Junior 2 and then the 3 and the 4 are senior pipes. The 3 has more bottom end, while the 4 pipe has more top-end. I believe back east they use the 3 pipe almost everywhere?

Cool thats what i was hoping for. im in michigan so hopefully when you say east you also mean midwest! so i assume its good to have a 3 and 4 pipe for different tracks?

Well the pipes are run in different class. There's a specific class for 3 and a specific one for 4. I think most places besides the west coast only use the 3 pipe.
