Greg,
This is an approach that I had pondered once also.
The only thing I was warned about by by boss (really sharp mechanical
engineer) was that if the pump was designed to sit so that the suction
was submerged in the oil. Then simply adding a longer pickup tube to
this would raise that portion higher than it was designed to be and
thereby change (dramatically or insignifigantly He said he could figure
it but would need the pump design specs to do it) the pressure drop
across the pump.
Based on my not knowing and too lazy to drop the pan on an old motor I
just let it pass.
You have rekindled my thoughts and I'll be looking at a pump tonight.
I'll pass on anything I find out.

Skip and I were enjoying a Guinness or two with several other classic bike owners (and a lot of HD owners) last night at the "Quaker Steak and Lube" restaurant and hang-out. The conversation was filled with tales of all the bikes the Indian Motorcycle Company rebadged and brought into the country up into 70's and how we all kind of wanted to have a 200cc or less classic bike ride every once in a while (Bantams, Stornellos, etc.). The subject eventually turned to Guzzis and then to loops and then to my quest for a sump extender. So, Skip so simply states, "Why don't you just cut the bottom off a loop oil pan and use it as an extender?" It was just then that I had one of those "Why didn't I think of that?" moments :> Seems simple enough to me and a spare pan seems easy enough to obtain (Skip even has one at the ready for me). Although I don't have inside measurements of a pan, they look fairly shallow from the outside. Maybe I could get 3/4" to 1" of an extension? Not extreme, but probably a definite help. And not too low as to become a concern when riding over speed bumps, etc (Thanks for the heads up on that, Gordon and Skip). Then, all I'd need to do is extend the pick up a wee bit lower and get some longer bolts. Any thoughts on this approach?
