I don't really have that much practical experience with living with a
Convert, although I have wrenched on a couple. I understand that the
charging system can be a problem. On paper, I know that the 'Vert has a
20 amp alternator. Not huge, but a popular upgrade for the 15 amp unit I
used have on my old "T". I wouldn't think that an extra couple of amps
for a pump would be a problem. I think the problem with the Convert
charging system is that the engine revs can be pretty low at normal
cruising speeds. Is there a fix for this? I'm thinking maybe a re-wire of
the stator, improved rectifier and/or regulator, swap it out with a more
modern alternator (newer Guzzi). Or I guess for the custom, put the
Kubota alternator on and belt it to an appropriate speed, like was
mentioned before.

Sorry about all this Convert crap. Just remember, Mike started it <:-).

Hey, what is the rear-end gearing for the Convert? Isn't it way high?
Maybe that is what John's buddy needs for his Merc looper.

could drain
the system of juice quick..
which catalog page was that gear pump? - i couldn't find it..

 I don't know the specs on the stock pump. I guess the purpose of
the pump
 is only to circulate fluid through the system for cooling, right?
I
 suppose we could do some testing. I looked in the McMaster-Carr
catalog
 today. They have a gear type pump with Delrin gears and a 12VDC
motor for
 about $47.00 I'm not sure how a fuel pump would work, but this
gear pump
 would probably work good on ATF. Rated for 13 fl. oz./min 20 PSI
or 63
 fl. oz./min @10PSI on 200 CPS fluids. Max temp 200 degF. 1.6 amp
draw.
 
For guys that maybe aren't familiar with McMaster-Carr, they are a
huge
 industrial supply house. Probably every manufacturing plant in the
US has
 at least one of their big yellow catalogs in the maintenance or
engineering office. They have a great web site too
http://www.mcmaster.com. I buy lots of MC stuff from them too.

 but what flow rate is the stock pump putting out? can't be
much..
 
 1 amp, seems like a big draw on the convert's electrical
system...

 Solid state Facet fuel pumps are rated at about 1 amp on a 12
volt
 system (www.pegasusautoracing.com) for race cars. The lowest
flow
 
 rate
 15 gal/hr @ 1 psi with a maximum fuel pressure of 2.4 psi -
4.5
 
 psi.

 I think I've heard about that bike. He's using the pump
so
 
 the
generator
 
 
 is in the stock location and he has a stock looper timing
chest cover.
 
 
 Interesting idea. Greg, do you know what kind of pump he
is
 
 using?
