GS1100G Road Runner Project

[londonboards]

Got my next GS1100G today and the idea is to have it on the road right away. This is the second GS1100G in my ownership at present. The first one is having a total nuts and bolts rebuild that looks like taking another 18 months at least. See here:

My Dad's GS1100G Rebuild Project Thread

So I bought this one to get me on the road as soon as possible and eventually to be either a parts store for the first one or to complete a running restoration on.

Here she is:

Bit lumpy. Middle 2 cylinders wet on the plugs. Outer 2 are tan coloured.

First jobs: carb strip and valve check (thanks Agemax!) and some tyres and to take it for a vehicle inspection (MOT in the UK).

Lets get this guy on the road.

the rear tyre looks good, is it just old?
i would do a basic electrics makeover as well. nothing to serious but just go through it and check all grounds are clean and tight and the same with all the block connectors.
you can get more involved later on if it needs it

Age - I think the front is done in but rear looks OK:

Forget the tread depth and brand name, what are the last three or four digits of the DOT code?

Do they have those in the UK? You might need to just recommend a maximum age.

 

[Agemax]

yep, we have them on UK tyres as well, except nobody takes any notice of them, even the MOT inspectors......

Fantastic! I see you have an 80mph speedo with 13 k miles. Nice low miles to bad your limited to 80mph. I never go more than 80. Your inspiring me to get mine going. Thanks for posting and cheers!

Great looking second bike and the fact you were able to start it, fantastic. Ya, those tires are toast. They'll never pass inspection anyways. Funny how the bike started right after you stood it straight up instead of leaning on the kick stand. I doubt it had anything to do with anything, probably just the fact you primed the carbs enough but sure was funny on the video. Good job! :clap:

Slap some new rubber on it and ride it! (Love the picture size/resolution by the way!)

More Examinations

I think this means new seals.

And some weeping from around here:

Not sure if that is gasket or the rubber D causing the problem. I guess it's new of both.

Stator/rectifier seems to be working.

 

[Charlie G]

Yes it looks like you have a bit of "Basic Maintanence" to catch up on. I wouldn't consider the meter readings real strong and would clead up all the electrical connections to see if you can get that 13.36 up to 14 or so. I'm glad you're getting to play with something that is running. It helps keep the soul motivated.

Love the brand of meter you have. I wonder if the Archbishop has one? Forgive me.

Charlie - You are so right. My restoration of the other GS1100 has been going a year now and whilst I am delighted at the progress, I can now see that at this rate it would be at least another 18 months plus before I get it back on the road. I do not want to rush it.

So having this other bike which is nearly roadworthy is great. I will soon be back on the road and be able to join some of the local bike meets (Suzuki Owners Club and VJMC) and runs. And being around other bikers is always good for the soul.

Thank you for your support.

More jobs to do

More jobs to do

Got a few more jobs to do to get this baby running sweetly:

Carbs off:

Bit grungy inside:

Rubber bungs nice and soft - I am suprised:

New manifold 'O' rings for sure:

Made in Germany sold in the UK. Why would it need to have a DOT code?

Cleaning the seals may work, and those tires are toast. Crispy critters.

Strip Down

Strip Down

Getting going on this little project now. I only have a few weeks to get her on the road before winter rears it's ugly head and fair weather bikers like me retreat to the garage.

See My Road Runner Blog - Strip Down

Cam cover off first (I should have noted which length bolts came out of which holes)

I used Steve's Excell spreadsheet and measured all the shims and clearances.

This one was tight:

Cleaned up gasket surfaces:

[Agemax]

that is why you have running issues. you have refitted the spark plugs upside down!

Carburetor Clean and Rebuild

Carburetor Clean and Rebuild

Ultrasonically cleaned them and rebuilt them with all new 'O' rings.

See My GS1100G Road Runner Blog - Carb Strip and Rebuild

Found this stuff in the needle valve filters:

Made sure all passageways were clear.

Checked out float heights. They all needed minor adjustment.

Cam Cover and Airbox Cleanup

Cam Cover and Airbox Cleanup

Cam cover was a mess of silver paint (so is the engine!) but whilst it was off I stripped it all off.

See: My GS1100G Road Runner - Cam Cover Clean UP

And I also cleaned out the airbox and installed a new air filter.

Re-Installed Carburetors

Re-Installed Carburetors

I squeezed the carbs in using planks of wood.

See: My GS1100G Road Runner Project - Re-Instal Carburetors

You need big pieces of wood!

Nearly did it like this:

But then ended up like this:

Then I discovered the choke assembly return spring was in between the wrong carbs. Should be between carbs 3 and 4!

So they all came off again. Then when I put them on again I discovered the intake boots were upside down so, as you can see, the carbs did not fit into the airbox boots. Take them off again and fix.

Greetings

Great job.

Keep going...
