Picked up a Craigslist GS special today. Going to restore it over the winter.

82 GS450T

Probably going to leave it stock and get it reliable. Doesn't currently run, but then again most of the bikes I bring home never do.

I'll keep you posted on the progress. For right now its going to have to wait until the 550 is completed - Thats a whole other story...

Wish me luck - I'm sure I'll have plenty of questions.

how does that bike not run?

really good looking

how much did you get it for if you dont mind me asking
 
Nice looking bike. I like the seat. But come on, gonna leave it STOCK???? What's the fun in that? :-D I mean other than having a reliable bike that'll get great gas mileage
 
Thats another good lookin lil bike byrd...where do you keep finding them?? lol
 
piston siezed up...

piston siezed up...

The cylinder walls look good but one of the pistons must be seized up. I had hoped that it was a starter or hydro-lock issue but unfortunately not. The head, cams, and tops of the pistons look fine. The cylinder walls are even shiny and rust free. I didn't go too crazy trying to push start it in case the previous owner had done something incorrectly to the bike. He had rebuilt the carbs right before this happened and replaced the starter as well.

Right now its sitting up with PB blaster pooled up in the cylinders. Its also stuck with one cylinder TDC and the other, the one i suspect is stuck, at BDC:-|.

Anyone have any good ideas on how to un-seize a piston - with the least amount of damage:-D.

Shiny as in nice and pretty? Or shiny as in glazed. Because shiny isn't really what you want to shoot for.... I always thought that the pistons in these twins moved simultaneously (excuse my horrible spelling). And as for unseizing the piston you're heading in the right direction with the Blaster. Let it sit for a while. Chances are that its just them rings rusting themselves to the cylinder walls..... If your lucky that is.....
 
Did the PO possibly screw up the starter installation? Not familiar with the 450's starter clutch etc. but sounds like that is probably not your problem. I'd take the starter off and check that out.

That was my first inspection to see if the starter was installed incorrectly or a failed unit. I've heard of starters wanting to stick if they sit on the shelf long enough. everything was fine.

There was a bit of oil in the stator area and actually in the physical stator, maybe a teaspoon or two - is this normal? Haven't ever needed to tear one down in this direction and it seemed odd.

I've torn the bike down to the cylinders (removed the head). The clutch assembly is still intact, but the transmission spins freely in neutral so I'm assuming its fine. It was a little tight however.

I'll let it sit up for a few days and see what happens.

Thanks for the help guys.
 
Ive only had to pull the stator cover off of a couple of bikes, fortunately for me, but every one ive pulled has had a lil bit of oil in it, i think its pretty normal.
 
Yeah, the stator is in an oil bath for cooling, perfectly normal to have a bit of oil drain out of the case.
 
Got It Free - Yessss!!!!!!

Got It Free - Yessss!!!!!!

The issue wasn't with the pistons... The P/O had some how gotten the timing chain wedged to bind the crank. He most hove done this when he removed the carbs and the cam chain adjuster.

The motor turns over free as silk and the cylinder walls look great. I filled the cylinders with 10-40 and turned the motor over repeatedly to ensure.

I removed the clutch assembly and was able to get a large wrench on the crank. I reversed direction of the motor and pulled on the cam chain at the same time. Popped the motor right loose \\:D/.

Glad i didn't go crazy trying to push start it.

So there it sits until I get done with the 550. I just couldn't stand not knowing what was wrong with it:-D

I'll keep you posted...
 
Good! Not having to fool with the bottom end and split cases is always excellent news! :-D

I'm sure if you drug the bike behind the car far enough, that kink would have worked its way out on its own!

I was really surprised the chain didn't have any damage on it. I wasn't quite sure how hard he tried to push start it :shock:. Evidently not that much.

I ordered up an engine gasket kit last night. Not too much out there for the carbs so I'll probably just Chem dip and go through them since i know the p/o was messing around with them with this all transpired.
 
She's alive! she's alive!! muwhaaahaaahhaaa!!!!!

She's alive! she's alive!! muwhaaahaaahhaaa!!!!!

Fired the old girl up for the first time last night and I must say it even surprised myself :-D.

It barley turned over tow or three times before it fired up like i had parked it there the day before. Turned the choke off and it purred like a kitten.

I was pretty cautious about the CV carbs when I went to tearing into them since I have only messed with VM carbs and other mechanical slide carbs in the past. I guess I was worried about the whole vacuum slide concept, but I have to admit I think they may be a little more forgiving than the VM's. That or I'm just getting better at carb tweaking :shock:.

I still need to clean up a few electrical problems and install a new rear tire, but there is only a few other feelings in the world that compare with bringing an old bike back to life...
 
Well its ready for its new home...

Well its ready for its new home...

Well I finished all of the work on the 450 I picked up and cleaned it up a bit.

What do you guys think I can ask for it?

Its an 82 model in excellent mechanical condition. The chrome is in great shape and the paint on the tank is good from about 10 feet away. There are some scratches in the paint on the tank. The side covers look great. New rear tire, front has plenty of life left.
