Marble any time you change the exahust and it's the TOP FRONT line to the air intake. The bottom line goes to the back of the front cylinder and is the PCV line. That one you should cap, run extra hose off the back of the rear cylinder and take that up and over the back cylinder and drop it into the space in front of the shock where the CA models have a carbon box. Put an aftermarket filter on it to keep the bugs out. That will keep you from getting oil drips out of your BAK.

Also, when you go to hook the BAK up, put a towel under the stock air filter to catch the oil that has collected in the bottom of it. It's there, you'll see, and you'll cuss if you don't make provisions for about 1/4 to 1/2 cup of oil.

Underneath the tank there is a set of hoses and you need to marble the top one which connects to the bottom line of your BAK. I never cap the bottom line under the tank which connect to the upper line of the BAK, just make sure you don't over fill the oil on your next oil change and you shouldn't see any on the filter. It did happen to me once though.
