what a nice find

[Spyderman]

so today i'm driving up my street and i look in my nabour's driveway and what do i see
a 1978 GS750 with a sign on it $100
motor won't turn over
tank is perfect all the bodywork is perfect it has never been dropped
it has 12,000 original miles on it
so i'm gonna buy it tomorrow i'll get it running for the wife for her to ride
ohh and it has the stock exhaust on it that are in nice shape just a little surface rust and i mean a little so all in all a really sweet find
any thoughts on the best way to break the engine free without tearing it down?

Drop some MMO and some PBBlaster down the spark plug holes... I would try to turn it over by hand (19mm socket on the nut at the end of the crank on the ignition side) and try to FEEL where the lock up is. Those motors are pretty tough (straight cut gears, roller bearing crank, etc etc etc) so it may be locked due to something other than the crank or pistons seizing up. If it wont budge with some persuasion on the nut there, dont force anything. Let it soak in that MMO and PB and check it now and then..if its still stuck like chuck, it might have to come apart. BUT, no worries, i have all the parts you might need...heck i even have a whole motor

well i haven't had a real good look it was only a 5 second once over and the kicker didnt move anything however it may have been in gear so i don't know yet
ya i was thinking some MMO and some seafoam
as for parts i would like a dual disk front end for it and some of the suzuki star mags it's gonna need tires
it's gonna need a seat recover for sure
if i do need parts i will shoot you a PM thanks

it's a 77 i went and had a closer look today the motor is ceased
it needs brakes and tires to start with if i can get it un ceased
so i'll have a bit of work ahead of me but i still think it's worth the $100
here's the frame and engine numbers
frame #GS750-19586
engine #GS750-19546

any thoughts on this would be apreciated
thanks

Once you get past the seized engine, here is another alternative for a replacement seat cover.

Yeah, it's worth $100. Just a bare frame with a title is worth that much, and look at all those 'extras' you got: tank, engine, wheels, body panels, etc., etc.

Damn you lucky!

You could easily part it out for several times that amount if you didn't feel like fixing it.

as i was reading a post a couple months ago, these finds come along once in a great while. I would have snatched it up in a heart beat. Good find for you.

Nice find.. can't wait to see a few pics of it

Nice Find...only thing my neighbor ever has in his driveway is trash or his cranky old self!!!! LOL

so i bought it tonight $100
wheeled it across the street and pulled the plugs to find that they were burning pretty well before it was stopped #1 was a little rich on the pilot but the other 3 were spot on so i poured 2 capfulls of seafoam down each cylinder and put the plugs back in and i'll let it sit for a day or 2
i went hunting for marvel mystery oil but it doesn't exsist up here that i can find so seafoam will have to do for now i hope it breaks free and i can then go to work on getting it running
the more i look at it i find that it is in great shape and is 100% stock
the tank is empty and totally free from rust it's perfect
i need to overhaul both breaks front and rear calipers and master cylinders
a chain
battery
clean the carbs
and tires
and clean up the electrics
i'm tempted to keep it totally stock
but i'm a little concerned about the exhaust it looks like it's in good shape
it's only got minor surface rust but i'm a little worried about the baffels but we'll see how it goes when i get there
so i think i know what seized it now
the tank is dry and the oil level is up by about 2 or 3 liters so i figured it leaked gas down the cylinders and the remnants of the gas turned to varnish and seized the pistons in place

My neighbor builds custom bikes I've asked him this before for a bike i purchased. He says in his experience you should spray enough PB Blaster in each spark plug hole to completely fill the cylinder and let it sit a day or two. Then try to slowly turn it over once you get it turned over do this again and let it sit again so the blaster can absorb into the metal walls and rings and piston. I did this after a V65 Magna sat several years and it turned over with alot of smoke and no issues. Good luck great find, good for you.

Good advice. Diesel will be just as good. It has penertrating properties but will lubricate better than blaster. Dont forget to change the oil when you've got it turning over though.

And my fathers favorite concoction is 3-parts diesel and 1/2-part auto trans fluid and 1/2-part brake fluid. For the wet clutch application, you would either have to remove the clutch basket/plates or forgo the brake fluid.
