30 series driven unit

[USApunk7]

Hey i just bought a new comet 30 series driven unit. And when i got it i realized it was a 6" diameter instead of a 7" diameter. I bought it from gokartsupply and i wanted to know if they take returns. And if they dont would i just buy a smaller belt or what.

could you space it farther away from the JS?

since its bigger, it will slightly change your ratio.


what was wrong with the old one?
