The "Bomber" GL1100 project - added video
« on: Feb 06, 2010, 07:17:49 »
Here is my current build, a ‘81 GL1100 café “Bomber”. Since my last name is Fortress, and always had a soft spot for WWII aircraft, because she was no fighter, too damn big, so it must be a Bomber!
 A guy at work wanted my old mower when I got a new one and had a bike to trade. He told me that it ran but wouldn’t idle so he parked it. We made the swap and I could see I had a lot of work ahead.

First off was the Tupperware. Then the fake tank and fenders.


 DAMN what some PO’s do to their bikes! This mess was for that Vetter fairing install.

No matter how much penetrating oil and soaking, I could not get the engine to turn over with the back wheel in gear, so I pulled the heads to check the cylinders… “Ran when I parked it” he said.

Then came “The old BattleAxe” parts bike for $200 that also had a stuck engine and no title BUT came with a spare engine that had the heads off for inspection… nice, now I guess I collect old GoldWings!


Stripped the Bomber down to a sandblasted the frame and got it painted with 2 part epoxy paint before winter set in and started the clean, paint and polish of the usable parts.

Bought some aluminum headlight mounting ears, a big ole 7” headlight, cats eye taillight,  and a set of broomstix from cycle-X, and mini catseye turn signals and a new front M/Cyl off e-bay.


Drilled / resurfaced the front rotors, need to pull the rear back off and drill it.

Here is where we are today, I got the gauges done and remounted but DAMN they are huge, looking into mini tach and speedo. Spray bombed and decals on the fake tank and side cover s from the parts bike for a mock-up…



 Now working on the engine now that I got an  Athena complete Gasket kit, got the heads done and prepping the block for painting then will be ready to install…

After getting all the mating surfaces cleaned up I got the heads installed last night... Sweet!

To give you an idea of my vision, found this picture on e-bay and is really close. A little photo-fix to remove his rear fender and here ya are.

Hey there Hoosier, killer build! I like the paint scheme very much and am enamoured that there are a few more out there that are cafeing some larger bikes. I thought my GS850 was overkill and have often wondered about doing a GL1100, so glad to see I'm not the only one.

With all that gear stripped off it, it'll be a real monster onroad - no denying the presence it'll have or the torque on tap from basically zero revs. Are you planning any engine mods while you're in there?

Cheers mate - boingk

Thanks all, yea I am really stoked about this bike so it's been pretty easy to stay focused on the build. As far as engine mods, about the only thing I have done is clean up the ports on the heads before I lapped the valves. Performance parts for these are kinda rare. Exhaust wise I am a little better of to with my earlier GL1000 headers. Still searching out mufflers.
 As a coincidence, the replacemment engine is an '83 which has slightly different gearing mated to the '81's original final drive...
lower 1st gear (2.642 compared to 2.500), YEAH!
same 2nd (1.667)
taller 3rd (1.20 vs 1.286)
Taller 4th (1.00 vs 1.065)
and taller overdrive 5th (0.829 vs 0.909)
I'm gonna use that torque cuz my '81s final drive is not quite as low as an '83s this engine was originally mated to (3.091 vs 3.10) ....now figure in the secondary reduction within the engine to trans connection on an '83 (0.897 vs 0.973). That lower first and the loss of weight will help me out of the hole at the stop lights, but you can see she's a hybrid suited for top end out on the highway... at least I won't be looking for 6th gear!  ;D

0.829????

Geez, talk about a moon-shot top gear! You'll love that one out on the freeways for sure. Hell, it'd probably almost pull it from a standstill with a bit of clutch abuse.

Sounds like you've got a bit of a creation there, should be interesting when it gets up and running. A good porting won't hurt her, thats for sure.
