Put almost 250 miles on yesterday with the DK outlaw breather bolts installed. Everything from puttin around town to an hour or so at 70 to 80 on the four lane. Not a spec of oil anywhere that I can see. Really happy with them and they look good. No tubing to worry about routing. YMMV
It wont effect anything by having the external vent with the Check M8. If you had left the air cleaner ventilation as is it can help toward having a slight vacuum in the crankcase, which is ideal. But having the external breather mod and the Check M8 won't negatively effect anything. You'll still be getting better crankcase ventilation.
Copy. I just might revert back to stock on the A/C plate, easy enough
