In the lower half of the photo is the hose full of blue 2 stroke running into my SOHN, just above it are the 4 clear lines running from the OMP to the injectors...but there's no evidence of oil in them? This picture was taken after a 45 minute highway drive, cruising at 3500. The level in the reservoir did go down, but not by much.

Is this abnormal?

 

The bit that I can see looks like it has oil in them...the lines are normally clear...but are very thin...so they will look grey with the blue oil in them. Could be the picture though
