Fx Ho Rpm Kit
me and a friend are putting on the whole rpm kit on a 06 fx ho on the mr-1 engine there is a cover over the motor..throttlebodies and airbox i think to prevent water intrusion we we're wondering should you still run it with this cover or is it robbing you air and rpm's with it on?

just wondering because it looks like evne without the velocity stacks there isnt much space between the air filter and the cover.

the filter pulls air in from the sides not the top, so yes keep the cover on!

what top speed are you getting with the rpm kit and is it a big difference with the velocity stacks and power filter??? do you have any video clips of how it sounds because i have a 09 fx ho and im planning on putting the free flow exhaust but wanted to know how it sounds

to be honest. i installed each part of the stage one kit on my 06 fxho one at a time and i didnt get ANY speed till i put in the impeller, but it could have been because of my bad wear ring and chipped up stock impeller.
