Anyone have black box for 300ex? I'm going to get the one from Pro Fab atv and i was wondering if anyone had it. How much more power will i get on top end? Just curious on people's overall reactions to it. THanks.

 

You won't get anymore power just more rpms and its a pointless mod to have on a stock machine.

 

Very good mod if your looking to blow it up!

 

It's not a stock machine. I have a complete lrd exhaust, i jetted the carb and i put a 36 sprocket. The rev limiter kicks in too early. When I hit the rev limiter she wants to go more but can't, the motor actually gargles.
