my engine has 26K miles on it and is burning oil ,the spark plugs are fouling .The right one needs to be replaced at least every 500-1000 miles.A local mechanic suggested to use a oil burner at the end of spark plug as a stop gap arrangement.Where can i find the oil burner for 4929 sparkplug(tried a hotter sparkplug,the result was the same).If i use these oil burners ,can it trigger premature ignition /combustion.
What will be the cost of piston ring kit and gaskets,approx cost for rebuild.I am on tight budget what are the alternatives
Manoj
Just in case you hadn't thought of it, plugs fouling can be signs of a rich air/fuel mixture :dunno_white:
Oil might also get past the valves.
How do you find out if the problem is due to rich fuel/air mixture and how can i adjust the same
Manoj
I would first eliminate the mechanical fault possibilities with a compression test.

How much oil is the engine using? Is it smoking? Are the plugs oily, or just dark?
The plugs are identical condition to oil fouled one in the below link...the oil consumed may be around 5mm on the dipstick from the last oil change 2000 miles since and I had overfilled a little above the max line ,would this would have caused excess crank pressure.

Well if thats the case, its not that bad of an operation if you can turn a wrench. Valve seals it is!
2000 miles and it drops 1/2 way in the dip stick.
Yes get back to me when it drops 1/2 way down in 300 miles. Cos I ran a 89 till that point, it ran fine and @ 48 miles I sold it.
A qt in 300 is still useable. Mine never smoked BTW. Plugs used to look wettish and sooty. But get them nice and hot and it was all soot, you have to run the bike for 20 mins atleast each time you start it. Else you would ahve unproportionately high consumption.
Cool.

I thought all GS500s burned oil...

mine doesnt, it an 07 f with 8000 miles and has never lost a drop, but its new so it might "break in"
Watch it and report back at 20K.
Cool.

Mines a 05 with over 36,000 kms and it hasn't started burning oil yet (touch wood)
But I do use either a 10w-60 or 10W-50 weight oil.
I use 5w-40 castrol full synthetic
Bhuddha unfortunately my rides in winter are very short may be 5/10 min,its a small town where I live in,can get one end to the other in 5 min.Today checked up the oil level once again it had lost may be around 3/4 mm on dipstick in 2000 miles,how much loss of oil does this constitute.I plug in the heated gear sometimes it draws about 100watt power,is this by anyway causing colder sparks and affecting the plugs.The job you did on the carbs in Feb is awesome ,have done 8000 miles since without any problem almost always starts on first click ,do you think its due for meddling the carbs again. Past couple of days ,temp has dropped 10 degrees to around 25 here and engine seems to run better.

If I remember right that's less than half a quart. That's really good for a GS and no where near enough to oil foul a plug.
That consumption rate is not enough to warrant a teardown. You can check compression but I'll bet it's fine.
You live in a small town and it's cold. Methinks that your bike is never fully warming up (short rides) and that it's running rich staying on choke.
Past that, this is more of a carb / fuel mix issue, so we'd need to discuss carb setup and jetting, carb balance, etc.
I rarely use the choke,if i did leave on the choke for sometime...would it make the engine getting hotter faster

OK, you're saying that your bike starts up fine with no choke in 25F weather.
I think it's safe to say you're running a bit rich.
It does start without choke most of the time temp around at temp 30 and the bike is parked it in an open air parking lot too.

If you're rich, you can wash the oil off the walls ... and get plug fouling ...
However you cannot lean it if you're doing short rides only.
Top to bottom of dip stick is ~1/2 qt. 2K and 1/2 qt is nothing ... I'd just try to run it longer.
BTW you charging the battery with the extra 100W draw and short rides ?
Cool.

Yeah, that sounds a bit gassy :D
What's your carb jet size / needle shim setup, intake and exhaust setup on your bike? I'm wondering if you're jetted rich or if you're pulling gas through the vacuum line.
my friends driving behind my bike noticed excess black smoke coming out of bike and the the left plug to be more oil fouled than the right one.Earlier there was leakage from cylinder head and I could not make out if engine was burning oil or was due to leakage but after fixing the leakage with new gasket the loss of oil seems to be negligible.

ya, you're rich. like dumping-gas-out-the-pipe rich.
i thought 1/2 a quart or 1 full quart between changes was a good thing ? ;)
Blue is oil ... black is rich, white is really really rich.
Floats is the first stop IMHO.
Cool.

tonight the bike just wold not start, low oil pressure light was flickering and sometimes the light would go out.Does the bike start up only when low oil pressure light is on?.checked the spark plug the left one was oil but the right one looked alright.would the bike start with only one spark plug working.Drained the battery trying to start,should pick the bike from school in morning.First time GS left me stranded..........girlfriend was mad
Manoj
Not sure what your problem is but the oil pressure light has nothing to do with starting, it just senses oil pressure. If that light does not go out with the engine running, shut the engine off immediately to prevent damage. I hope you get your problems sorted out so you can enjoy the bike :thumb:
-Jessie
the spark plugs need to be changed every 200 miles and photos of the condition of the sparkplugs just replaced.......how badly would the rich mixture affect the cylinder wall by the carbon deposit.
