lots of smoke
not sure if this is the right section in the forum but hopefully i'll find an answer ,old 1979 gs850 chop , 4into2 exhaust ,pod filters, rejetted , bike was running a bit strange so changed to sparkplugs and after change of the sparkplugs the bike started smoking quite badly and smelling fairly bad when warm and hitting higher revswhen pulling up , running idle the smoke seems to fade away even when warm it doesnt smoke that much when running idle , starts at the push of a button even after standing still for a week , checked oil levels ,had to much oil in it initiall , oil seems farly dirty at the moment as well but drained a good bit of the oil to get to correct levels and still smokes , a bikebreaker nearby suggested fuel and oil addative to flush out the engine but with the oil cleaner it doesnt seem to make any difference , i have noticed that the inlet manifolds are a bit worn but dont know if false air could cause white smoke , wondering what it could be my biggest fear is the rings , mostly because i lack the tools and space to fix it lol , any ideas ?

If it was oil burning it would be blue smoke not white. How much fuel have you ran in it? Next fill up try some dry gas additive. Run a compression and or leak down check on each cylinder. Try changing valve stem seals. What does the oil smell like? Bad rings will leave a hint of gas smell in the oil.

Sounds like a tired engine. The plug was fouled so after replacing it, and the cylinder firing again, the smoke started.Ed

the oil didn't smell of petrol when i drained it , smoke is white with a bit of smell of an eggy fart , not sure what a tired engine means though , i got a gs 1000 engine offered to me but the problem is the drive it's a chain instead of a shaft otherwise i would have just changed that over unless i can take the drive from the 850 and exchange the chain for shaft on the 1000 cc one , i got a box of valves lying around but wondering how easy that is without taking the whole engine out

Do you have, or access to a compression gauge?sigpic
Don't say can't, as anything is possible with time and effort, but, if you don't have time things get tougher and require more effort.

nice weather ...... maybe nice is to strong a word , but best weather we can get lol
dont have a compression gaugethe thing with my gs is that she runs fine(apart from the smoke) starts easy ,plenty of power 0 to 50 in matter of seconds , so not sure if i have leaks or loss of compression anywhere unless you dont notice that in performance in these old beasts

Here is your very own magical, mystical, mythical, mind-expanding "mega-welcome". Please take notice of the "Top 10 Common Issues", "Top 15 Tips For GS Happiness", the Carb Cleanup Series, and the Stator Papers. All of these tasks must be addressed in order to have a safe, reliable machine. Now let me roll out the welcome mat for you...

So
1. Test your compression
2. When did you last adjust the valves?
3. Test your petcock
4. Check your oil level daily
If it's running well, and accelerates right up to 60 as it should, the motor is not worn out
Are all the plugs bad, or #3 especially bad?
The white smoke is from some other minor issue, especially since it just started happening one day,probably not the rings
And sorry, the 1000 chain drive won't swap (yeah, I read your other post)1978 GS 1000 (since new)

trying to get my hands on a compression tester , not checked the valves or adjusted them , got a manual to do it but cant figure out how to with the way they word it lol , plugs are fine
there was to much oil initially in the enigne but changed that to correct levels
speaking about oil , i want to drain completely and change filter and top up oil again , asda nearby sell gastro oil 4 litres cheap but read different things about using a car oil in your bike (something to do with anti friction additive in the oils ) just have normal bike oil in the bike just now ,but i thinks it's ready for an oil change anyway
what oils can i use (motorcycle oils here are beyond ridiculous compared to car oils )

It is possible to have a failed head gasket. But smoke could also be caused by oil leaking onto the cylinders or headers from the tach cable send unit, or the valve cover gasket. If you like, clean the motor well and check for leaks. See the tach cable seal repair here: Replace Tach Cable Seals.
