This engine has close to 300 miles on it in the last couple weeks and all good so far. There were a few more mods done to the oiling system than
just drain holes in the cases. When I took the original oil pump apart it looked as though it had been pumping gravel. Good condition pumps
or pump gear shafts are not very common so I thought I would make one. I bought a few used Ducati Monster oil pumps on eBay and found that
they are still using the same pump gears although the shafts are a bit different. The gears are also heat treated now, the originals were dead soft.
So, while doing this I realized now was the time to make a pump body with a fitting to pump direct to the filter and filter all of the oil.
Pump body made, shafts modified, still using the tapered drive gear but now with a bolt instead of a nut and few holes to lose some weight.
Pump testing. I could only run it up to half the rpm it would be running at when the engine is at 4000 rpm without taking a shower in oil.
I read every full flow filter write up I could find several times so a lot is the same. Ream a .5 hole thru the center and drill out the small oil
passage to 8mm.
I couldn't see a good reason to have a fitting on both ends of the tube running from the pump to the filter so used 2 short pieces of .5 stainless
tubing with ends ground so they could be tig welded together. That slides in the upper .5 reamed hole and the pump gets a straight pipe that
slides into the upper fitting.
Slide the tubes together, bolt the pump in and a drop of green Loctite on the joints and done.
Even with no Loctite the pipe pieces can't move.
