Looking for help or someone to work on my '82 GS850G. AKRON-KENT OHIO

Hey guys,

I'm relatively new here, and this might be the wrong thread for this, but I've had the worst issues since I've gotten my 850G a couple months ago and I'm looking for help. $1200 down and $800 invested in tune up, carb clean and new tires and it's running terribly after my 800mile trip to and back from NYC.

My problem now is that the bike is missing at all speeds, it burns oil, and begins to smoke at a sitting warmup after 20 minutes. I'm teetering on the edge of just selling it as I'm a student and having the time to work on it is slimming substantially. I miss the way it ran when I first got it, but I'm okay with investing in something new as well.

I'd be willing to pay cash for help or if someone would like to work on it as a side project, that's fine too! I don't expect I can get much out of it as it isn't the prettiest, but if someone can make it work right for less than a bike shop, I'd throw some $$$ your way.

Best,

-Pickleson (Dylan)
 
"$800 invested in tune up"

With an old bike, best to do this work yourself or be fleeced! Have you see Basscliff's info warehouse??

I'll wildly guess that your petcock failed you (it was running ok you said )and is dumping gas into your crankcase causing all sorts of fun. You need to immerse yourself into maintenance- pretend it's a required course!
 
What do you mean by this....begins to smoke at a sitting warm up after 20 minutes. You mean your starting it and letting it idle for 20 minutes or you ride it for 20 minutes and THEN it starts to smoke???
 
I wish I had the time for maintenance right now! UGH the pains of being in college and working full time.

It will idling and then start to smoke from the top of the engine.
 
Well its an AIR COOLED ENGINE!!!! Do you have fans blowing on high into the front of the engine as its idling?? If not your over heating the engine and all the crud thats in between the fins is starting to smoke from the heat.

If you DO have fans on it and its still doing it, I would first agressively degrease and power wash the engine to be sure its not crap burning off. Then see what it does again with fans going.

Is the engine clattering or otherwise giving signals youve heat damaged it yet???

No fans, just letting the bike normally warm up. There is some putty from where the header meets the main engine block, which I can send a pic of (from previous dis-assembly work by previous owner. I guess my biggest issue is the missing of power and burning of oil. And by missing power I mean it feels like the bike barely works (rough idle, no power to go above 30mph). I cleaned the gas tank just last week and checked the petcock and its dispensing fuel properly, but I'm not sure if there's already too much in the crankshaft as wildly guessed by the fellow above.

I am really quite stumped and I am new to working on my own GS. I've stopped riding it completely until fixed.
 
Not sure how to tell you this, but a "normal" warm-up means:
1. Start the engine, modulate the "choke" to keep revs under 2500
2. As soon as engine speed is steady (about 10-15 seconds after start-up), put on helmet and gloves
3. Get on bike, RIDE.
4. About the time you are in third gear, turn "choke" off.

If this is not happening, your bike needs some maintenance and/or adjustments, and for SURE, the nut that holds the handlebar needs some adjustment, too. :-\\\


There are some members up in your corner of oHIo, but if they can't/won't help you, see if you can find a way to get it to my corner of the state, it WILL get running. :encouragement:

Lol thanks Steve. If I can't find someone around here, I might just venture down your way sometime soon!
 
Maybe your petcock is not "dispensing fuel properly" -might not be blocking flow when engine is off (do you understand "PR " spot on petcock) or fuel could be dribbling down vacuum line . Get some clear vinyl tubing and stick on petcock vacuum fitting and suck- if you see fuel in this line, your petcock is no good.
 
Hauling you motorcycle down to Steve's and leaving it with him for a week or two would be money well spent. Just be sure you clean it as best you can so Steve doesn't have to get to dirty...
 
Ahhh indeed the petcock is dispensing fuel when in RUN position when the bike it off. To me understanding, no fuel is supposed to run unless a vacuum is applied via the vacuum hose.
 
Hopefully cleaning the petcock will work! Will do a full oil change and bleed the case empty and access damage afterwards.
 
As Tom said. Dont waste the time or money on trying to clean or rebuild a petcock..its a loosing situation. Replace it with new.
 
While you're strolling around, find a decent hardware store,and look for 2 bonded washers (rubber bonded to metal washer). The 1/4 inch size works fine- these go under petcock mounting bolts to keep gas from leaking. About 40 cents each, so avoid trying to use the old ones.

Edit: on second thought , you might be looking for 3/16 inch size bonded washer. You want a 6mm bolt to fit snugly thru the metal. I don't remember the actual size that I got.
