Hi Woody, Glad to hear you're making progress on your pump escapades. I like the sound of what you've done so far. Im attaching a couple of pics of how I modified the supply pump to be a distribution block. This way, you get the use of the check valve, and route oil to all the places the stock pump did.
It's just an aluminum collar to block the ports on the rotor chamber, and a plug to fill the feed hole to the chamber. Also the hole drilled from feed to output side of pump.
I'm sure you've seen it before, but here's a link to the website with all the info on my pump experiments. http://www.freewebs.com/dicky_linn/thir ... typump.htm
I've just altered the pump on my 44U, which is the bike/engine in most of the pictures on the site. It now has the latest version of the sporty pump modifications. The side of the pump is cut off, new bottom plate, this time in aluminum. that way, there's no need for spacers under the motor mounts so the pump will clear the stock frame rails. Looks a little sleeker also. Interesting figures on pump output, The late sporty pump outputs 1 ltr/minute@ 2000 engine rpm, which appears to be less than your version, although your testing rpms were slightly higher. You're going to have plenty of oil for that motor now! I'm running full flow 3 hole crankpin, and skirt oilers, pressure drops to about 13 psi hot., 60 psi cold, but the sporty pump has NO bypass circuit, and I'm not using the one in the original supply pump. You may want to keep that circuit operational in the original supply body on yours. I've seen late model racing pumps that had the pressure relief valve built into the pump body, so HD thought it must have been a good idea, at least for racing. They never bothered on all the street sportys out there though.
Sounds like you're having fun with this, keep up the good work!
