1983 GS750E Project Bike

[spyug]

These are great bikes and rock solid when sorted out. There are a few things you should consider doing however and primarily it would be checking the charging system. The regulator/rectifier on these bikes is weak and can be the source of the problems. the solution is changing it out for one of the more robust Honda models (see our friend Duaneage).

In the meantime and as a temporary fix, you should add an additional groundline from the unit directly to the negative terminal on the battery. It is also important to make sure the contacts at the r/r ( and really all other contacts) are clean. On my bike the plastic connector was so gunged up that the only solution was to clip it off and replace with fresh spade connectors. That fixed things for me.

The bike is likely going to be hard to start too so you should adjust the valves as well as clean and rebuild the carbs. The coil relay modification is also a great idea to help starting as these bikes often suffer from resistance in the cicuits caused by corrosion and dirt at connectors and switches causing coils to receive less than necessary voltage for good spark.

Once the electricals, valves and carbs are sorted these bikes will run forever. As mentioned, they are smooth and powerful and will take you distances and keep you entertained doing it.

Enjoy and keep us informed of your rebuild progress.

Cheers,
Spyug

Thanks for the advice Spyug. The good thing is I now have a parts bike for anything that could go wrong.

You have gotten yourself a new nice bike, really like the red.

 

[rapidray]

That is 5418.4 MILES! Not kilometers on the parts bike. Just thought you should know. Ray.

Thanks, I prefer the red one too!

I figured out it was in miles yesterday but still extremely low mileage for an '83!

Yup, SVSooke is right on the money..........both my GS 750E's are 1984's.
These are the E models and did not come with either of the fairings Suzuki offered. They have the enormous 8" headlight up front instead.
The red one is the one I use regularly. It had 65,000 kms (39,000 miles) when I bought it and now has 77,000 kms (46,200 miles). Bought it as a project - rebuilt the front forks, greased the steering head, swingarm and rear suspension pivot needle bearings, new stator and rectifier, lubed cables, lots of time getting built up grease and grime removed from the bike and finished off with a new set of tires. Heads up - the head/swingarm/rear suspension bearings were dry with hardly any grease left on mine.
The second GS, in black, was also purchased as a project and only has 33,000 (19,800 miles). Did the same work as above on that one except for NO stator/rectifier replacement and tires were ok. I'm not sure which one I'll use this coming summer at this point in time. I just may have to go with the black one to see how well it runs.

I'm with Mrs Sooke - I like the shade of red on your bike. Looks very good, indeed.

Picked up my second '83 GS750E today, it was a snowstorm outside. Borrowed my nieghbors truck and had an uneventful ride home, took it real easy, roads were slippery.

Here's some more pics at home in my garage.

One thing I noticed is pretty much every single wire is disconnected. PO owes me some parts - chain, front fender, chain guard, 2 small pieces for the stock exhaust. Will pick them up next week!

Now, where do I begin!!

There are quite a few well done restorations and modifications done on '83 and up 700 and 750 bikes here. Joe Whelan's 700 is about as sharp as they come. King of Venus, Salty Monk, and I have all modified ours pretty heavily suspension-wise. You can shave 40-50 lbs off them with a little work.

Here is a picture of mine.

 

[SVSooke]

You where going to paint the white one metallic red IIRC.Guess you don't need to now.

 

[Patman]

Nice bike Kingofvenus, that's a big diet to lose 40 to 50 lbs Billy Ricks! My first concern is to get it running. Not sure of bike's history, PO only had it for 2 months.

Yeah Sooke, I won't have to paint the white one, just strip and paint the white windscreen to put on the red bike. I'm going to pull the carbs out tomorrow, just got my O-ring kit! Sooke, I'm going to try the Pinesol soak, will let you know how it went! I need to put oil in it to, PO told me it's empty and no filter either. Bought some 15W40 Diesel oil after reading the forums here.

 

[Patman]

Did some work today, got the carbs out, changed oil and filter, removed fairing, replaced some missing cosmetics.

The factory exhaust was rusting and had lots of holes. Sandblasted it and then welded it back together.

 

[safarijack]

Does the parts bike have an igniter??

 

[Smokinapankake]

I have a soft spot for these 750/700's. Especially as my 84 Katana is basically the same thing, only dressed in Kat's clothes. Great bikes and underrated, in my opinion.....
Will be watching with interest!

Got some more work done today.

All the wiring was apart from PO, I mean every single wire disconnected, some were broken, some were cut!. Had to re-wire and scavenge lots of parts off the white GS. The white one is looking more and more like a parts bike now!! Got the red one to turn over today, good sign. Next week, carbs will go back in and hopefully a test fire.

I need a choke cable, some more wire for the rear signals, an electronic flasher for my new LED signals, front fork seals and a chain - not too much!

Pics will follow!

 

[Patman]

Pics as promised:

SuperTrapp Pipe is going to be sandblasted

LED Turn Signals

LED Front Signals

 

[Patman]

Here's my Supertrapp exhaust all sandblasted, painted and installed.

The only negative was having to remove the centerstand. The right side spring was interfering with the connection for the pipe.
