Air Suction System removal.

My 550a arrived with this already "plugged" and there seems to be little or no magic involved. Just rubber caps on the carb, reed valve ports and air box.
Ironically, I went and replaced my carb mounts to get those vacuum ports so I could try out carb synchronizing. :laugh:

When I decided to remove all the emissions stuff on KZombie, I did things a little different; I connected the left reed valve port to the right reed valve port with a short (original) piece of tubing used by the system, even with stock spring clamps. The carb port was just blocked with a new rubber boot made for this and for the air box hole I had to get a little creative and found these rubber parts in the auto parts store that are made for replacing a master cylinder reservoir's cap/seal - basically a larger diameter rubber plug - and RTV'd it into position on the air box so it's not obvious and yet, still useable if later, I want to put the emissions system back on it.

The cleanest of all is to replace the cam cover with a non-US version that never had the setup.
