Anyone ever build a Tri-Magnum out of a GL1500?

When I was a teen, Mechanix Illustrated came out with the Tri-Magnum on the cover. Every few years I go back and look at the thing and think, I could build that. However what has always stopped me is the fact that I did not have a good donor bike for the project.
Recently I bought 2 Goldwings, a 89 GL1500 and a 84 GL1200. The 1200 is nice, looks good and just needs the alternator installed, I have ridden it and it is nice.
The GL1500 is a pig, about 50% of the plastics are broken, cracked or just plain missing. The seat is shot, the chrome is bad, the windscreen is opaque and it over all is faded and looks like a turd. However, I have ridden this also and it runs and rides like a dream. I will spend twice the value of the bike replacing plastics and other parts and it will still never be anything I can sell.
So, this got me to thinking, everything that is bad about this GL1500 with be removed and thrown away in the conversion and what is left is hidden under bodywork. I would basically strip it to the very basic frame, no plastics for the build.
Having reverse is a major bonus as is cruise control.
I am thinking I may adjust the bodywork to a more open cockpit with a roll bar, kind of a 3 wheeled convertible.
Where I live we get over 200 days of sunshine a year and less than 9 inches of rain.

Seems like you have to make it. You buy the plans, weld up a frame and work fiberglass. So you may have to make molds, too. Then, there's the windows.

I'm guessing these will be rare.

There's something even more unique out there and the 1500 can be used for it. http://www.autocycles.org/ I have seen these and one will come up for sale every now and then that needs a new engine.

They use the back section of the motorcycle from the engine to the rear wheel.

the 1500 will present a major problem if he wants to use Reverse.


the 1800 found in a slavage yard will be better.
like the one that I got my spare parts from, it met up with a stopped car.... front end a total loss, from the triple tree back, it was like new. the 1800 has Electric Reverse.


for me, that thing spells Sweat Box, no ventilation, and for sure, no a/c.

I saw cars something like that when I was in Germany in the early 70s, don't know what they were.

With no God over the state, the state then becomes not the defender of liberty but the definer of liberty.

If I disagree with you it's simply because you're wrong.

The company headquarters is in Chandler. Like you, I don't think it could be used much in the Valley of the Sun, SoCal, Florida, etc.

Also may not be a good choice for the claustrophobic.
