78 GS750E in Indiana

[wedoo2]

I picked up my winter project today. An E model with only 9400 miles, but the bike is in crap shape. Absolutely not taken care of. Do not be fooled by the pictures because it does not look that good.

It runs, but not very well. Obviously corroded carburetors. Does not want to stop, in fact it feels like the back brake is wanting to seize the wheel. And the tank has the look of someone had a problem with it. You'll see.

My plan is to get this bike fairly close back to stock, but I'm not yet sure I want to keep the paint scheme the same. I really like the orange and red stripes on both one of the 450s I've seen, and a late 70s CB900 F. But keep it black. Oh, and keep the headers. I have Kerkers to put on it, but will need baffles. This is really one of my dream bikes so I intend to keep it. I usually sell my winter rebuilds. Will need a fairing of some kind, so we'll see what is available down the road.

Lots to do in the meantime. Carbs, brakes, bearings, cables, clutch basket look at, oil, and new paint and shine on the motor. Will be a slow deal, but I will keep this current. If there are any issues with the 78, please let me know. I've done this before on other bikes, but I am certainly not an expert. Here are some starting pics

From the front.

Filthy motor and rusty headers.

Side view with mismatched drag pipes.

Is this worth fixing or should I try to find a new one. Insides are rust free.

Your input is encouraged, except cut it up for a cafe.

Looks like someone might have stuffed a 110 front tire in there... you'll be replacing the tires anyway, but make sure you remember to check and order the correct sizes.

Good luck with the project! Should be pretty straightforward.

 

[wedoo2]

It's a 100/90. When it is done, I will change the tires. Who knows how old these are. Front is not terrible bad, but the back has been burnt out a few times.

 

[Ledyard]

Great to see another Hoosier 1978 GS750, Terre Haute! I look forward to your updates. What are you thinking for pipes?

 

[wedoo2]

I was kind of in your area yesterday Ledyard; went to Toledo to sell my last project. Lots of prairie up there. It has some headers, 4 into 1, that I think will fit the Kerker muffler I have. I love the looks of the original 2 into2 but most likely too rich for my blood. Who knows, maybe has a good deal here.

 

[tkent02]

That dent looks doable, be careful or you could make it worse.

 

[tkent02]

Look at the date codes.

If they have no codes they are from the seventies. A three digit code it's from the eighties or nineties.

I am looking for suggestions on vendors for some parts:

Brake Lines (SS or Rubber)
Master Cylinder Rebuild Kits
Caliper Rebuild Kits.
Carb Kit See link--is this enough or are there o-rings I will need? I understand the o-ring for the manifold boot needs replaced as well. http://carbkitscapital.com/carb_kit_list_model.php?make=Suzuki&model=GS750E
Clutch & Throttle cable

Should I post this to the discussion thread? I appreciate the input.

Rear Tire is 1986, but the front is great. May use it, we'll see.

 

[Road Rash]

That dent looks identical to the one on my bike. Gonna strip the paint then tackle the dent pull before giving her a proper refin.

Yup rear tire is way too old to even think it's safe, though what is the date on the front, just because it looks great doesn't mean it should be used. Besides from what I can see in the photo, not sure I like the way it is sitting on the bead. I would think a 90 is large enough for the front.

I could not find a date on the front, but I'm going to change it too. I'll get whatever the right size is.

I started tearing it down today. BTW, there is no shut off position on the petcock, RES, ON, PRI. Didn't see anything different in my manual either??
Ain't those headers purdy?

You know, maybe clean your motorcycle, at least once a year.

The chrome on the front fender, the headlight are in good shape. The chrome on the back side of the instrument housing is scratched on the right side. Forks, handlebars, brake calipers will clean up like new. We'll see about the tank. The motor will be coming out in a couple of weeks or so. Need an air filter cover. Try to find one of those.

Petcock is vacum activated, on, res. work only if engine is running. Prime allows gas to flow without vacum, good when bike has been sitting a while and needs a little priming. If on, or res. work without engine running means it's not working properly and will need replaced. terrylee

 

[wedoo2]

Thanks, I thought I had read something about that. What creates the vacuum?

 

[wedoo2]

This looks like a great deal. One difference in the jets vs the manual from BassCliff. http://www.ebay.com/itm/FOUR-NEW-Su...e:Suzuki|Model:GS&hash=item2576885379&vxp=mtr

Main jet 102 in kit vs 100 Hardly seems significant, especially with 4-1 exhaust

Comes with float needles and O-rings. Anyone have a problem with this? Obviously still need the manifold O-rings.

 

[wedoo2]

This is what I have decided to do with the paint scheme. Need to figure out the decals, but I have always loved the 79 CB750F look. These are much better bikes than those Hondas. We'll see how it comes out. Little photoshop magic.

wow, I just did my carbs and got the kits which look exactly like this but without slider needle for 23.00 ea...x 4 =92.00 and when you do the carbs, get a couple egg cartons etc for parts and label them, also label/number the carbs and keep track of everything in a clean organized work area with good lighting.

 

[wedoo2]

My problems come with tuning part.

 

[wedoo2]

Trying to take off the sprocket cover and I have removed the five screws pointed to in the pic. Is there something else to do to get it off?
