Big Bertha, The bike Honda never built
Several years ago a friend who knew I worked on old Hondas offered me a 96 GL1500 that had been sitting in his garage long enough his wife was complaining. It had belonged to his father-in-law and had been partially dis-assembled and sitting in his garage for some time as well. Anyway I helped him smooth relations with his wife and haul it away. No one remembered what the original problem was or where all the parts were. The brakes were both frozen and the clutch would not release. A winch and two healthy old-timers managed to scoot it onto the trailer. Then it sat at my place. Over the last three years I have occasionally messed with it a bit. First confirming the engine would turn over, then doing a compression check (all good) and spark at the plugs. Then sitting another year. Gradually assorted components were removed in an effort to get back to the basic motorcycle.
About a year ago I managed to get the carbs out and cleaned. If you are not familiar with this bike the carbs are wrapped inside the frame and covered with spaghetti. Something like 12 vacuum lines, three drain hoses, two water lines to the radiator,an air duct from the left manifold to the air box, two drain lines from the air box, and probably more that I am forgetting. Since I had removed the fairing and assorted tupperware with associated check valves and relays, I just plugged the vacuum lines with quetips. I installed a cheap after market fuel pump and a new battery. Maybe spark plugs, can't remember for sure.
Anyway, to my surprise it started up and sounded great. The clutch was still stuck and the brakes frozen but it was running. There was hope.
We migrated north for the summer so it sat several more months. Upon return, it would not start, the fuel pump quit working and the carbs had to be pulled again. The idle jets on both carbs were clogged and had to be cleaned. This time I bought some vacuum caps at O'Reileys an did away with all the vacuum lines. Left off the cooling lines from the radiator and didn't bother with the cruise control hardware. Another cheap fuel pump was installed. ($40 new vs. 350+ used OEM).
It started. Meanwhile the brakes were redone, the clutch cured itself and the wiring was sorted and modified. A test ride of forty or so miles confirmed it was going to be OK.

Re: Big Bertha, The bike Honda never built
My original idea was run it as a rat bike. Maybe add a sub-frame and turn it into a reverse trike. I even bought a VW front axle. But after scrounging through my junk I came up with assorted items that seemed to fit and it just evolved. The speedo is from a BMW (seems very close to correct speed) Tank panels from a GL1000 separated by stainless steel scavenged from an old propane grill cabinet and pop riveted in place of the original metal of the panels. Fuel cap access is from an old Honda sport bike of unknown origin. Top box is GL1100 and side boxes after market from a ratty old GL1000 I acquired. Truck bed spray hides all the wear and tear. Headlight and running lights are mounted on a homemade bar that I copied from another old rat bike I acquired some years ago. The dash panel was also acquired from the propane grill cabinet but I plan to replace it with a Trail Tech Vapor enduro speedometer, which I have used before and is a bit more elegant.

Re: Big Bertha, The bike Honda never built
I cheated and bought a Valkyrie, but I've loved this idea of a stripped 1500. I'm surprised at how well a GL1500 + GL1000 shelter panels work. You got a genuinely cool looking bike there.
1997 Valkyrie- Light Cutomization, but Too Busy Riding
1980 KZ1300- Bike's Haunted
1976 GL1000 (Yellow)- It Runs (Poorly) and Doesn't Leak (Mostly)
1974 Velosolex 3800- Better Than Walking
1972 CB750- Broke the Chain And Ate the Motor
1969 CT90- The Most Fun You Can Have on 90ccs.
1965 CA77 Dream- Needs a Full Teardown, but Complete
All advice I give is only valid until an expert corrects me.

Re: Big Bertha, The bike Honda never built
Thanks all, it surprised even me with how well it turned out (and how fast it runs) Best of all I probably spent very little over $500 in total including two tires, two fuel pumps, a battery and misc. paint and odds and ends.

Re: Big Bertha, The bike Honda never built
Looking Great!
my "Naked 90" has taken a back seat the past couple of years, she is just a frame with wheels, but i have managed to shorten the handlebars by about three inches.
In my opinion the center of the front wheel looks ugly with the covers off, but i think they look much better with some stainless steel mesh fitted in the center.
I got the idea from another Naked 1500 i saw on the web.
All the best, Peter
