It's not really my style, and I have heard its always flinging an oily mess. Don't know for sure, but like I said I have only heard.

Go with number 3.

Another question. Does anyone know what kind of a system the joker machine or the figure machine uses? Meaning, does it breath back oily air or is it similar to the dk custom and use the breather bolts? Also, if its different, could one utilize the breather bolts?

Both Joker and Figure route the hot oily air back into the throttle body and combustion chambers.

Both Joker and Figure a/c's for Sportsters can be fitted with DK Custom External Breathers to make their a/c's let only clean, cool, dry air into the engine.
