Phoenix Rising! The GS1K v3.0 build.
« on: January 26, 2017, 03:02:10 pm »
v1.0 - As purchased. I know dad has a shot of it the day we picked it up in NY. Will update.
v1.6 - Got it running right,  repainted black/white.

v2.0 - Rebuilt after my brother skipped it down the road.

v2.9 - Top end rebuilt with mild performance upgrades. Now an 1100, relocated electronics,  oil cooler added. Braced swingarm, different exhaust and a new paint job.

v3.0 - The rebuild after yet another family misfortune. Follow along as the Phoenix rises , quite literally,  from the ashes.


So it's been some time since the accident and everyone involved has thankfully healed up nicely. Except one, the GS frame has been sitting there,  burnt and bare, waiting. The time has come to rebuild.  This time it's going to be an all out resto-mod, heavy on the mod.  The GS purists are sure to cringe as I bastardize both versions of GS they worship, the 1978 'E' and the 1979/1980 'S'. 

Step one,  we need a clean canvas so the sad, singed frame was delivered to Automotive Sandblasting. We were slightly concerned the heat of the fire may have affected the metal. We assumed the steel wouldn't be but seeing no evidence of damage on the bare frame was a relief. Chris applied a coat of etching primer to prevent flash rusting and so we had a surface to mark on.


Early on in the conceptualization of this project I knew I wanted a 4-valve 1100 engine from a later GS. During the hunt for the 1100 engine I found an entire 1981 GS1100 for less than the price of a complete engine. To top it off, the bike was in my wife's hometown. Chris and I had quite the adventure picking it up from MN. Before we removed the engine from the donor bike we did a compression test.  The cold, dry results were 175 to 180 across the board. We were relieved to find everything with-in 10%. Then I looked up the factory compression spec, 171 peak! Above spec,  cold,  dry on an engine with 50k+ miles? Something interesting is going on in there and I'm looking forward to popping the top to find out what.  First though,  this lump needs a bath.


To be continued.

We're mocking up the bike to sort out how everything will fit.  Last night was spend getting the motor mounts sorted to put the GS1100 engine in the GS1000 frame.  Now that we have a handle on that Ian's working on getting the spacers and bearings sorted to mount the GSF1200 Bandit swing arm to his old frame.  Once those are done we need to decide where the shock mounts will go for the swing arm's conversion from monoshock to twin shocks.  Ohlins shocks are already on hand.  Once the bike is loosely assembled it's off to the fabricator to have gussets and braces welded into the frame to make it AMA Superbike racer stiff.  Progress....

From Ian:

This may not look like much but this is the result of my labors so far. The Bandit 1200 swingarm is in, the 16v 1100 engine is in and the frame is almost ready for a date with a welder/fabricator for the bracing and detabbing. My old Suzuki is getting closer to being back, better than ever.

I was just looking at the pictures again and realized that those lower shock mounts still need to be welded to the Bandit swingarm.  I think that we probably need to have that done before toting the bike off to have the bracing welded into the frame since it'll be easier to move the bike if it's a roller.

Anybody know a really good aluminum welder?

More progress today.  Bearings in the steering stem.  Temporary front suspension installed.  Trial fit of bodywork. Engine centered in mounts and tightened down.

Shock mounts welded on.  Need to polish and then slightly unpolish the swingarm and install the bushings.

OK, that's the rear suspension just about sorted.  Now to get the right GSXR front end up front and we have a chassis.  You mentioned you have a wiring diagram you wanted to follow for the wiring loom I'm going to make.  If so, let me see it and I'll start ordering the wire and connectors.  I'll also need a copy of the wiring diagram for the instrument pod you bought.  I think we should go with a Shindengen SH775 regulator/rectifier rather than the stock set up as it'll run cooler and be easier on your stator. 

Do you want to retain the stock Suzuki self canceling turn signals or go with a simpler set up?  If so, we might want to replace the stock handlebar swiches with some new production early Kawasaki copies made for the restoration crowd.  They would look period correct and offer the reliability of new switches while looking much better than the pretty beat up Suzuki items.

Philosopheriam on The GS Resources has a fantastic build thread for his own bike and I really like his harness (his whole build is just amazing). His electrical section starts on page 35 and goes for a few pages. His harness will have to be adapted somewhat for the gauges and I'll be running my electronics under the seat. I was running a MOSFET R/R on the bike before and planned on going back with one.
http://www.thegsresources.com/_forum/showthread.php?224534-Progress!!!-1978-GS1000E-Restoration-Performance-Rebuild

His harness schematic: https://www.dropbox.com/s/u0wmti4evr3u21x/Wiring%20Schematic%2C%201978%20Suzuki%20GS1000%20with%20Relays%2C%20Rev%201.1.pdf?dl=0

I'd never been inclined to call a wire harness beautiful before but his is.
