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. Loopframe
tool box locks, vibration mounts, various hardware, fateners of all
types. Order online and they ship it fast!

 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.

be all
over

 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?

 i saw an ambassador vert setup at the ohio rally which had a

chopper oil tank...
i'd like to put an electric pump on a vert project i'm
building
 
 
 
 (pump is
missing from timing cover...) anyone done this yet?

i have 2 verts with the lighter flywheel (one of which is
the one
 
 
 
 i'm
building above..), i have a spare heavy flywheel, but
haven't used
 
 
 
 it..
they say the lightweight flywheel is unreliable, i haven't
had a
 
 
 
 problem
yet. but then again i only have maybe 10,000 miles on the
vert..
 
 
 
 
there is a yahoo group for verts, that someone may know
more..
 
 
 
 (mgconvert)
is the group..

 Hi Mike,

Well, I certainly don't consider myself an expert on the
subject,
 
 
 
 but I
 have worked on a couple of 'Verts. Hopefully, I'll be
putting some
 
 
 
 miles
 on mine when the weather turns. I fixed one that had a
broken
 
 
 
 flywheel a
 couple of years back. I believe that bike had about 40,000
miles
 
 
 
 on it,
 and it had a sidecar attached. My current bike has 26,000
miles on
 
 
 
 it and
 it still has the original sheetmetal flywheel. The point
I'm
 
 
 
 trying to
 make is, I think they can last a long time. I know Dave R.
in
 
 
 
 Guzziology
 says he thinks it may have something to do with
engine/tranny
 
 
 
 alignment.
 
I have never ridden one with heavier wheel, so I can't
comment on
 
 
 
 how it
 affects the performance. I'd say your choices are:

1. Go with the sheetmetal flywheel and know that you have
the
 
 
 
 best
 performing set-up, but you may have to get in there again
if you
 
 
 
 put a
 lot of miles on (and you might get stranded somewhere. I
wouldn't
 
 
 
 want to
 have to change a flywheel along side the road).

2. Put the machined flywheel on and never have to worry
about it
 
 
 
 
 breaking, but you'll always wonder how much quicker it
would be
 
 
 
 with the
 lighter one.

It really depends how much it would bother you to change
it if it
 
 
 
 did
 break. I'm not changing mine until it breaks.

I don't see why you couldn't build your own ATF reservoir.
I don't
 
 
 
 know
 if there are baffles in there or not. I'd saay you could
probably
 
 
 
 modify
 a chopper oil tank.

Good Luck!

Anyway, here are my questions....
1. I have a perfect earlier/light flywheel that I'm

my Convert Custom...Guzzilogy says that the bikes are
quicker

flywheels?
 
 
 
 My

than a

 >Convert...
2. Any reason I can't build a custom tranny fluid
tank for my Custom...would the quantity that it holds
have to
 
 
 
 be
 >the
same or could it hold more tranny fld?
