It has a fin kit you have to pruchase seperatei feel choice 2 will have a hard time cooling.
ShortYou running long or short track?
The jet is no bigger than a 31 and a no go of 32. Stock air box and weenie pipe only allowedJust my opinion the lite flywheel you need the fast acceleration of the corners and if your jetted correctly and timing is close don’t tape it up ( no fins to catch any air anyway) if your running to hot the karts way to tight anyway
