I refer to my previous post regarding the oil lines running from the base of the motor to the oil cooler at the head. I suggested that this may be a design fault. After pulling the pipes off the bike I had the aluminum pipe welded, cost $20. I have now found other places where the other pipe was rubbing against metal, a crack was being created. I will split rubber pipe and glue it on as protection, plus I will use plastic ties to secure the pipes. I recommend that riders check these pipes before embarking on any lengthy ride. If I had not seen the puddle of oil at home I may well have blown the motor through no fault of mine.

Yes , I was just looking at that yesterday, the outboard pipe can even rub against the left radiator if not installed correctly, there is about 1/8" clearance on my bike, it will get "rubber hosed". May not look like it is rubbing at standstill but different story with the air pushing against all that at speed.

They can also rub against the bellypan at speed, I was getting some wear marks, had to put some stick-on foam on the belly pan to prevent that.

Rubbing against the engine, depends a lot on the orientation of the banjos, I now have at least 1/2" clearance, don't remember what was there from OEM but I had to change the orientation slightly anyway when I installed my oil pressure gauge. No relying on the idiot light for this guy, comes on at 12-15 PSI on an engine that runs at 70-75, if I bust a line I should know pretty quick before wrecking my engine.

Regarding the pipe contacting the radiator. I observed that, it was touching. I loosened the screws on the plastic , the part that holds the retaining clips for the pipes. I then jammed a screwdriver between the pipe and the radiator. I then re tightened the screws. No problems. There is room for movement there.

I split 1/2" car heater hose years ago and put that over parts of my KRS oil cooler lines.

I was probing about with a mechanics stethoscope to nail some engine vibrations and found a point where the lines if not properly set in their clamps, could touch the frame and or plastics and induce vibration.
