Was mostly wondering the power difference playing with the airbox would make and playing with spark at the moment. I might be wrong but it looks like the prior gen airbox would fit so that could be a fun experiment. I'm also looking into making slotted cam gears just to see if they'd be worth it...
I believe this is what you're looking for. It's in the manual just labeled weird.
