GS 750 es : Let s bring it back to life!

[Loki]

Hey nice score on the bikes, gonna watch you work em over

[SVSooke]

As the resident "expert" I can tell you the white bike is as it says an ES.At some point it's gotten E bars though.The red one is a 84,paint scheme gives it away.Put penetrating oil on the header bolts,every day for a week.Do not rush this.Did 3 exhausts and not 1 broken bolt.Also get a hand impact driver and use a 12mm socket on the end.Dr Greg's recipe for a successful exhaust bolt removal,no guarantee mind you,just a fighting chance.Hitting every bolt you are going to try to remove might be an idea to,give it time to work.BTW WD40 is not a penetrating oil,found that out in my build,I use Lloyd's Moove It.Works great,others do to I'm sure but that's what I use.

[Flyboy]

Ditto, nice catch there, I will be following with interest.
A mate of mine had a 750ES which I did many miles on, real fun bike, light and nimble and a rev monster, loved t sit in the second half of the rev counter, serious grin factor those bikes.

I think i ll try that one, want to make sure i won t break anymore bolts,
i ll try penetrating oil for a week.

is the torch technique something i can use in peace?

Never used a torch but I don't really have one either.Do what you like,just found this worked for me.

i will try your suggestion first anyway, don t get me wrong!
was just wondering if the torch thing is doable on motorcycle engines without taking unnecessary risks.

EDIT:
BTW, thanks for helping me out to find which bike was what!
what actually are the differences between a E and an ES?

[Patman]

The "E" has a little 1/4 fairing like this:


The "ES" has a larger fairing and different clipons. Nice score on the bikes. My 2 are still a work in progress, I work on them if and when I have any spare time. I will be following your build with interest.

[Etcheberri]

Thanks Patman.

well i ll need to find a front ES fairing then!
or will i use a round headlight, it kinda look cool, but it s not stock... mhhh

[SVSooke]

The large round light was stock for the 84 E.Better light than the square one if that matters.

oh, that is good to know!
thank you!

[Etcheberri]

By the way guys, what is that weird brown varnish in my tank.
the metal seems clean underneath it, how do i clean that? do i treat it as rust?

[Etcheberri]

Okay,
so the thing in my tank is old gaz varnish, i think, so i ll take care of that with some lacquer thinner.

Tonight i removed the Carbs. not much but i am sick, got the flu, great.



Forgot to drain the fuel... ahah got everything on me, yummy!


they dont look that bad


but i am going to check the parts bike to compare an select which one i want to use.

tomorrow i ll clean these.
simplegreen first, for the grease.
then some carb cleaner.

i ll see what i can do for the exterior,
i hate that chunky spray-paint color on the covers, so i am going to sand them down.
or do i use a paint stripper?
and paint them later on. (i need a small oven of some sort...mhhhh)

oh and buy some Hex bolts and new gaskets, if needed, we will see.




I kept going on with the harness removal/annotation process,
and well...

is THAT normal? i mean... why 2 of the wires coming out of the R/R are duct-taped like that? and not connected to anything? i ll check in my service manual, but i ve got too much fever to do something with my brain tonight.



more tomorrow!

[Etcheberri]

okay! here s some updates.

Bought some lil things to work on the project.
here s a part of it.


decided to clean parts as i go, then put them in respective bags to not lose anything.



3 screws are toasted, hum, should have waited a bit more maybe, anyway i ll drill them out.

i really will buy a full hex kit for carbs (suggestion about your best place to buy them are welcome!)

here s what my floaters look like

the gasket is kinda still softy.

i ll replace it anyway!

after some elbow grease

a bit more


jets and old gasket.

[Curly]

Those top caps are plastic! Don't use carb cleaner or paint stripper! You'll most likely damage them. Clean them real well with soap and water, maybe simple green, then use a little armor all, theyll shine right up.

[Etcheberri]

thank you curly!

they have been simplegreened, easy to clean indeed!

worked on the foot rest part (what it s name exactly please? i don t know it in english)
simple green, wd40, sand paper. i like it.
will re-paint the black part soon enough!



Used a tool on my drill to remove the stripped screws. got them out! YEAH!


i cleaned the chain guard thoroughly, man there was a LOT of crap under there! took a lot of time to remove.
sanded it down, then painted it with some Black bumper paint, wanted a solid finish for that piece.
(except on body parts i hate glossy finish. i plan to paint the whole engine in flat (or very low gloss) black, with red details)



the mess, so far. keep trying to keep it clean as i go... lol yeah sure!

and the es. so far, so good.
