[i] Only time it does anything good is if they are stuck shut, because then you won't get any top end power. So people wire them open so you get the top end, but you'll lose some power down low. [/B]
So, it's good to not have any top end power? J/k I know you messed up. They open up at higher RPMs to give the rotaries more air and fuel. You're right about wiring them open, not a good idea. Just stick with stock.
