If you really want a significant increase in speed and acceleration, swap the belt drive pulleys for 30t front and 68t rear. it's the biggest bang for buck upgrade on a stock bike, especially one with a mild cam, since the belt pulley change shifts your rpm ranges slightly higher and into more of an optimal range for the cam.

Anybody know is the Arlen Ness Big Sucker Stage 1 vents externally?
To externally vent the Arlen Ness Big Sucker you would need the DK Custom Products DIY Discrete Breather System. You can see in this image of an AN Big Sucker the stand-offs that are a part of the backplate have been drilled with an 11/32" drill bit and tapped with a 1/8" NPT Tap to vent the crankcase gasses to an external filter.
The DK Custom Products DIY Discrete Breather System comes with 6 feet of hose to give you maximum flexibility in positioning the washable breather filter. The drill and tap are available options for this DIY Kit should you need them to perform this upgrade to your Arlen Ness Big Sucker.
