           As air is introduced when you lift the control lever, check the pump back plate is still fully tightened (Black item that carries adjuster screw and has left hand thread). This can loosen when locknut is tightened or throttle is used.

      As for air in right side line, logic says it can only enter the system between the distributor valve and the engine check valve otherwise it would affect the left side. My money is still on the banjo seals on the pump, does air appear at the banjo outlet. Don't trust the flat alloy washers to seal, better solution is 'dowty washers' that have a built in rubber seal. Banjo bolts can bottom out on their thread before washers are fully compressed. Hair line crack in the banjo ?, these are known to suffer degradation of the alloy under damp conditions.
      Beyond the above, I am stumped and suggest you try another pump although that could introduce further issues. Keep going, you are nearly there.

To add, the oil line from the tank is perfect and the line running to the left cylinder is perfect. I just took the bike for a test ride and it drew oil to both sides perfect. Yet as soon as I slowed down about to park it, it started drawing air ONLY ON THE RIGHT SIDE once again. It also seems that when I manually bleed the lines by lifting the lever on the pump, that seems to add a very tiny bubble or two.

The confusion continues....
I decided that I wasn't sure how much I trusted the one check valve, so I decided to switch it out with a second one I had, since you can only buy them in a pair from richard. After switching the valvue, the pump seemed to work great. I let the bike sit for 20minutes or so running, no air leak. I then took the bike out for a ride and came back no air leak. Came out and started the bike up again this morning, ran for about ten minutes, still no air leak. I walk back after mixing up another gallon of gas, there is an air bubble. The pump is not consistently sucking air, but on just rare occasion it sucks air. This inconsistency has me very confused. And yesterday I did reset the timing on the pump and double check everything....what on Earth is going on?   :o I feel if it was something to do with motor timing or vaccume leak it would be consistent and the bike would not run as good as it does.

My pump seems to be working fine on a running motor. Just came across the spec. Seems only 1 cc/min. is the flow rate at my 1,500 rpm test rate is all that I could expect (see engine manual pg. 76).

Are the clutch & brake levers the same for these 2 bikes?

You're right it's like the standard.  The deluxe has oil injection.  I've seen a few different versions with the "surfrider" name.  Both high and low exhaust, single and double seat in blue and black.  Too bad no one knows the story?  Steve
