Hi Keith,
Don't believe the lies about the four speed being a bear to rip into.
The Guzzi four and five speed transmssions are very similiar in their
design and extremely simple to understand and work on. There do exist
complicated transmissions in this world - but the Guzzi 4 and 5 speed
transmissions are not included on that list!
All you need is a clean workbench, a few basic tools and a couple of
"specialized" tools, and a little mechanical aptitude. If you have a
digital camera, that's helpful too - but certainly not critical. Have a
read through the articles on my site (and also the articles I link to on
the GuzziTech site that were written by Pete Roper). If you are going
this far, I would definitely take the time to shim up the transmission
properly, replace all of the seals and gaskets, and give it a general
inspection. Regardless of what Guzziology says, the four speed
functionality can be improved dramatically by this work. This is one of
very few things with which I disagree with Dave Richardson.

You can bench test the trans. by turning the input hub and shifting it through the gears. This will give you idea of how well it will work, but isn't very definitive. Still lots of other things that could need attention. You can check the neutral light in the same way - connect a test light/continuity tester/multimeter to the stud of the neutral switch and ground it on the trans. housing. Shift into first and back, second and back and see if the light operates properly. If you found condensation in the u/j boot, I'd pull the trans. rear cover off for a look see. Could be rusted or pitted bearings, gear teeth, etc. from sitting. Better safe than sorry in my opinion. Greg Bender has done a few of the 4-speeds and has helpful insight from this on his website.
