-84 GSX 750EF after 24 years in a barn

[TonyGee]

their could of been a bit of corrosion or whatever on the selector drum ????  a good oil/filter change and some miles on it will help im sure.

Good news - see bit of TLC , waggle everything around , and it all comes round again .

My opinion only - These are solid engines , the electrics are stronger than the earlier GS's and the only real  weak spot is the suspension , your shock if still original is likely shot , and that 16" anti dive front end ...is easily swappable if you find it a bit crap . 

As TG says , get some miles on it . Mine sat for at least 11 years, and the only thing I did to get it up and running again was ultrasonically clean the carbs....& only because I have a cleaner . Odd oil leak , but nothing major at all .

I'd be tempted to say that the bike is acting better and better. I've put a few miles on it, here is a pic from today. Cheers

Looking good , might be worth ditching the 24 year old tyres before you go too far though  

Both my tyres were "legal" on mine in terms of tread, but you'd have been hard put to mark them with a Stanley knife, they were that hardened , certainty I did'n't want to go around roundabouts on them . 

It was the "new tyres on small sizes" vs " new tyres at modern (er) sizes " discussion that prompted me down the wheel swap route , and then it all snowballed ..

Not even sure if there are many options are on the old 16" fronts anymore (110/90/16 ??? ) Battleaxes used to be a good choice but think they have long gone hopefully someone else may have some good suggestions

Yep, they are closer to bakelite than rubber..like you said they are probably legal but definitely dangerous.
On the bike right now, front 100/90 R16", and the rear 130/90 R17". The rear tyre is actually chafing a little against the metal "support bar" that runs from the caliper to the frame, and looking at the specs in the service manual, 120/90 R17 seems to be the correct size so i guess i'll go for that.

 

Does anyone know what E06, 24, 27 and "The others" refer to?

The market the bike was originally sold in.

Thanks a lot Cap'n!
E17 it is then

Ah Swedish ....you'll enjoy these ol adverts then ! 

Allegedly Swedish models were 90hp not 86hp , however that might just have been the importers claim .

Beautiful ads!
"Newly excercised (in lack of a better translation) - 22kg lighter, 4 hp ("horses") stronger"
and "GSX 750 - The trend setter" (Trend creator to be precise, but i don't believe that's the proper expression)

Ah you see, I live and learn

I thought it said " comes in Flat Pack ...."

 

My son is off to live in Gothenburg this month , so he'll have to brush up on his conversational Swedish !

He's not a bad wrench monkey on this older stuff either.

A little update, i have been in the process of moving so there hasn't been much time in the garage, but today i could squeeze in a few hours.

New Pirellis, first time i have tried putting a tyre on a rim with tyre irons. Harder than i thought but it worked out with some harsh language.
Did the starting gas trick to set the bead, worked like a charm.
Will see if i can get the rear wheel sorted tomorrow.

I was tempted to put a lot of effort in making the rims look nice but the advice given by you fellas to prioritize getting her running and MOT'd kept ringing in my ears, so that will have to wait a bit.

New round black thing up front.

Cheers

[TonyGee]

a few swear words always helps 

[carl_87]

Got the rear tyre sorted, it took a quarter of the time compared to the first one, and the result was better. A fivefold reduction in swearing as well. Did a bit of cleaning around the rear swing arm.

After:

Before:

Purchased a small sand blasting cabinet, i have begun blasting some odd bits.

Thing to do before putting more miles on the bike, new brake lines and get the leaking front shock sorted..

[carl_87]

Ordered seals for leaky front forks, waiting on them.

Does anyone know if it's possible to buy a complete brake line kit, or is the best solution to just take all the measurements and custom order them?

 

Some cleaning and vinyl-shine-goop breathed some new life into the seat.

 

Sad clutch cover.

 

Happier clutch cover after blasting and priming.

Happy clutch cover. The obvious problem is, once some bits start looking nice again, the bits that previously blended in with the overall barn-found look suddenly look horrible, but i guess that is a classic problem with restorations.

Or Sprocket cover even ! A complete braided hose kit can be sourced here in the UK or do as a lot of peeps do and DIY them - SS fittings recommended, measure twice, cut once, clean and methodical - easy peasy! Its not rocket science to do.

Right, sprocket cover it is 

I might go the DIY way, i did some Youtube'ing and like you say, it doesn't look like rocket sience!

Evening fellas,
I am disassembling the front forks to change out the leaky seals. It's going well, but i ran in to a little snag;
This here aluminium cone fell out of the first fork. I was more careful with the second one and figured out where it came from, but i am not sure about the direction of the cone. Does anyone know? I would think it's the first option, but the exploded view in the service manual is not very clear..

New brake lines ordered, btw. Decided not to do the diy way,  found a kit at a motorcycle shop.
 

First option


Second option:

Thanks Tony

[carl_87]

The forking things are done 

New seals, new oil and gave them a blast in the cabinet and a few coats of paint when i had them disassembled, turned out nice.

Have not ridden yet, only manhandled the bike in the garage, but shocks seem to not leak anymore.

Now i'm waiting on the new brake lines..

Picture

[PanzerWomble]

It's looking a lot better than on page 1 , there was a nice bike in that barn .

[gsxwill]

It's looking cracking, you should be well pleased, 

[carl_87]

Thanks, it took some archeology work but under all the muck, there turned out to be a bike. I hope you like the updates, i sure am enjoying this project.

Brake lines arrived and installed, great fit up front, less great in the back (a bit too long) but it'll work. Steel braided but with a black cover for a stock look.

Things left to do except an MOT are mainly cosmetic. The frame has lots of surface rust and the engine has paint peeling off in all sorts of places. I didn't plan on doing that this winter though, maybe next. It’s about time this bike is ridden a little this summer
