kit NX
added stuff, NX gen2 upgrade has a window switch, warmer, purge, blow down tube.
It is also prob. the most pricy as far as kits go (esp. with the upgrade), but NX is rated at the wheels not the crank. And the upgrade is worth it to have everything you need.
also at 125 a new fuel pump would be nice but you "could" get away with out needing it.
