I recently got a 79 850 with electric and kickstart. It sat 20 years. I push the kickstart pedal down by handturn the motor over. It had no gas tank, wss sitting outside.i just drained the oil checking the bike out. I expected black sludge. It was light brown like weak coffee. I figure even though it does feel oily its probably oil and rainwater. I guess the engine is ruined even though it turns over.right?

I don't think you should be able to work the kick start with your hand. You weren't grabbing the clutch lever with your other hand, were you?1982 GS1100E V&H "SS" exhaust, APE pods, 1150 oil cooler, 140 speedo, 99.3 rear wheel HP, black engine, '83 red

Yes, you can. It surprised me at the time.Originally posted by Rob S. View Post
It's not really free and easy, you can feel some compression, but it's nothing like the kickstart on a twin.---- Dave

79 XS650SE - Pragmatic Ratter - goes better than a manky old twin should.

I just pulled apart a 77 GS550 that had water in Blogs cyl and it was rusted to the cylinder wall. Some PB Blaster and time, it freed up.
Removed the jug and the engine is free and worth looking into rebuilding. Not sure if I can save Blogs liner and I'm not about to waste $$$ removing and replacing this.
No option to bore it out over 1mm - no pistons available - only option is to find usable jugs (anyone?) or find a 650G and take the top end (anyone?)
So don't throw it away just yet - plenty of 850's out there that need help or are best for partsLast edited by unfocused; 10-18-2023, 12:04 PM.Current:

If it has water in it you'll know when you pull the oil drain plug since the water will settle at the bottom. As to compression you can expect it to be low until you run the engine a bit to reseat the rings.
If the oil seems to be water free after pulling the drain plug I'd hook up a battery to it and see if you can get it to fire with some starting fluid and go from there, it might not be as nearly bad off as you think!1980 Yamaha XS1100G (Current bike)

You omitted the most important details: Where was it sitting? Under a lean-to or under a tree? Were the spark plugs installed? Were the carburetors also installed? If it was stored outside in the rain and the answer to either of the last two is no, then the engine _probably_ needs anything between a full rebuild and a trip to the scrapyard. If the plug and carbs were on it to prevent water from getting into the cylinders and ruining them, it _might_ still be fine. The fact that it turns over at all is a good sign. If you want to turn it over any more, I would put some oil in the cylinders to give them a fighting chance.Comment
