anyone?

So the bike shop that has had my 82 GS850 for THREE MONTHS has now given up. According to them, they replaced the valve cover, synched the carbs, etc. did a bunch of stuff, and the first time they took it out, they found that the #1 cylinder wasn't firing, and when they tried to push it to force it to fire, a plug blew and oil leaked everywhere. He said he doesn't know if it's a bent valve or what, but they are through trying to figure it out.

Thanks.

So anyone have any thoughts on this?

Shop is owned by the devil.

Nah...you've got to credit Old Nick with more brains than this lot.

What do you mean a plug blew? Are they saying the plug came out of the head because the threads are stripped? Also when you mention they tried to push it to get it to fire do you mean push start it of push the mechanical limits if the engine (over stress it). As for the oil leak it would take an opening from the inside of the engine to the outside for oil to puke all over. I don't beleave a bent valve will cause the oil to leak. I generally don't like to be a pesimist my initial though is they took it out and an it real hard to try to get the dead cyclinder to fire and threw a rod. It of course may not be that extreme. You mentioned that the replaced the valve cover gasket, did you have them adjust the valves? if so they may not have gotten one of the valve shims seated correctly and the cam could have pushed it out when they started it. this would atleast contain the damage to the head are instead of the entire engine.

I think I would go have a look at the bike and see what you can see. and while you are there I would have them run a compression test on all four cylinders and see what the results are that may help narrow it down to a mechanical problem or fuel/air/spartk issue. Keep us informed and the more detail you can give us the better we can help diagnose the problem.

Yes, get it to your place, take pictures of it and let's get it figured out.

They're all crooks.
Incompetent crooks.

"Cry Havoc and let slip the dogs of war".........sounds like the dealer is incompetent. You are better off taking pics as has been suggested and doing the work yourself.

Probably lost one of the half moom cam plugs that they resused... Needs the carbs cleaned ????

Yeah, not much use trying to sync up a set of clogged carbs. As with any bike that has been resurrected from the barn or the back 40, START with a carb cleaning, sync, valve adjustment and points (if you have them) adjustment/replacement. Pretty simple and common stuff. Should be able to find everything you need right here, or on BassCliff's site.

Sounds like a case of the dealer trying to do something that they don't have the knowledge and/or experience to do. Most dealers just change oil, tires, chains and sprockets, and spark plugs. General easy maintenance that lazy people don't feel like doing themselves. The usual lackeys don't even know what points are anymore, let alone know what to do with them. Engine rebuilds? Troubleshooting? Not really worth their time to try to figure it out for what they refer to as a "boat anchor". They'd rather do an oil change and a wax job on the latest plastic fantastic or behemoth cruiser. There's VERY few dealers that I would even consider handing my bike over to. In my few years in bikes, I've seen a lot of stuff that was "fixed" at the dealer.

Ok, I'll stop my dealership hating rant now.

Take some pics of the engine that show what you're talking about and the good folks on here will be able to help you out, if not come by and lend a hand. We all love to see old bikes come back to life.

Bent valve?! BAHHH!
Get the bike back and do it yourself.

OR

Post the business's name, number and address here and we'll gang up on them and shame them into fixing it right.

[rudy]

I hope you don't have to pay them for not fixing (and possibly breaking) your bike.

1/ The 850 rocker boxes will leak if the gasket isn't on correctly.
2/ There's no way in hell that a plug will blow out of a head by pushing.
3/ If there's a bent valve no way it was pushed.
4/ Oil leaks. My GS1000 blew its head gasket after having a carb drop on me.
5/ No1 is possibly a blocked/gummed up carb or a duff plug cap/spark plug.

Either get the dealer to fix whats gone wrong at there expense or get it back from them and sort it yourself.

Thanks guys, for all the support. I'm going to try to figure it out after I get it back from the robbery shop. He is planning to charge me for parts, and I'm planning not to pay for labor. If he wants to push it with me, he's going to have a fight on his hands. (I work at a law firm)

You're right about them not wanting to deal with older bikes, or having the knowledge to do it. Lesson learned.
