smoking issues...again

[usmc_scott]

I thought this problem went away..guess not.

when first fired up it runs choppy. push in enrichener to first click runs ok. as the bike starts to warm up white smoke comes from the left header..guess i need to tighten it. and mainly the left tail pipe slightly on the right. if i shut the engine off the pipes both smoke for a few minutes after. like a smoking gun look. color is white. not as thick as it used to be. iv been googling and just get more confused some forums say its too rich some say its too lean some say its a gasket? but if it was something other than the ait to fuel mix it would be blue smoke right?

the carbs are off for the 5th time soaking in cleaner right now. slap em back on when i get the time and mess with the first 2 carbs idle mix i guess? how should i go about troubleshooting this one?

any ideas? btw i put some of that sea foam rip off stuff in the tank i found at walmart right next to the seafoam only 2 bucks! same ingredients basicly. see if this will help. and wont this cause smoke??

[CatatonicBug]

Seafoam in the fuel won't cause smoke at all. In my experience, white smoke is caused by burning oil. You may have oil in the exhaust already, and as you run it and it burns off, you will get less and less smoke. Then again, you may also have an internal oil leak.

[Crazcnuk]

White 'smoke' is usually water...

If it 'smokes' for a while after shutting it off, you probably have some oil or water, (both) in the pipes. Have you gone on any long rides to see if it burns out?

I hope not as soaking the carbs fully in cleaner is bad in itself as reported here many times.

it can be hard sometimes to tell the colour
of the smoke when its a light colour,
as craz said, white is water/steam and can be seen in water
cooled engines when the head gasket has blown,
or on an air cooled engine, moisture in the pipes and engine.
black smoke is a rich fuel mixture,
blue is oil burning, if it starts smoking on initial start up, on
deceleration, or after its been sitting for a while before its started,
its valve guide stem seals and/or worn valve guides.
if the smoke appears on acceleration and/or its extremely fumey thru
the engine breather its worn rings.
hope this helps you.

also with messing around with my carbs,
ive found if the enricher is pulled out all the way
and runs rough, and runs better on the first notch
when the engine is cold,
the mixture screws have been set a bit rich,
try turning them in a quarter of a turn each.

Well I havnt really taken it for aa ride except around the parking complex of the appartments due. To the fact that the front tire is bad and I didn't want to ride it till I found out why it smokes...iv never left first gear. Well I guess ill fire it up and let it run a good 30 minutes. Makes sence that there would be a lot of moisture/oil in the bike after sitting for years

fan needed

Don't forget to have fan blowing on the motor to cool it

[Crazcnuk]

I wouldn't worry about it. Just forget the smoke until you get the bike ready to use. Once you get the new tire(s) and what ever else it needs, then start to ride t, and a lot of those little kinks will work themselves out.

When I first started my 80g it smoked like crazy out of the pipes. I assume there was a lot of oil in them, no idea why, but it all burned out first 50 mile run I did. That was 30,000kms ago.

Mine also smoked when first started.

If your carbs are off I would check every passage from the float bowl through the slow circuit. from the float bowl through the main jet.
with a can of carb cleaner make sure all passage ways are clear step by step.
Be absolutely sure.
Bread tie sync before putting them back.
Mine would not run if I took it off the choke.
Make sure all cylinders are firing.
I have a 79F when I set my Idle screw out 3 and one half turns it helped.
I would also get a safe tire and try to take it for a decent ride.
With out riding it its going to be hard to tell whats wrong plus I think it will help to work out the kinks.
Up until last month I was going through what you are now.
This is what worked for me.

Hope this helps.
Good Luck
Rick

Thanks for reminding me about the fan garth. Hmm ok well ill forget about it I guess untill I get the tire and brakes in tip top shape.

Btw I noteced the front fender was..pinched in where it mounts to the forks. The brake disk rub on the guides? I tried loosening the pinch nut and spreading the forks back appart but it didn't budge. Po messed up the front end pretty bad huh

Smoke

When I got my bike up and running after 4 years of sitting, it smoked so bad I could only run it for a short time so that the neighbors would not complain.

After I started riding the bike everyday it stoped smoking all together.

These bikes are great, Don't worry about the smoke it will go away after you get some good rides on it.

I have put 1000 miles on the bike now, runs well, and no smoke.

[Crazcnuk]

As for the fender, is it the forks that are out or is the fender itself bent?

You can take the fender off and straighten it pretty easily.

On mine, the PO had the front brake rotors on the wrong sides, upside down. The fork seals were in, upside down, and the retainer clips had rusted away to nothing because the fork seal makes a great cup to hold water, when in upside down. There are two bolts in the fender, no idea why, unles he had a 'hood' ornament at some point.

my 650 maxim had the same "smoking gun" effect from one pipe. In my case it was a cylinder running rich at idle. I color tuned the cylinders and it cleared up.
It only did it if i started the bike and never took it for a long ride to let the engine get good and warm. It happened when i went for short trips. I think it was unburnt fuel in that cylinder causing it.
Anyway, a good synch and color tune makes many problems go away.

rings not seating?

In a bike that has been sitting I would suspect the rings not sealing and burning a little oil - which may work itself out with use as I have heard from others.

I agree just get bike road ready and wait to trace the smoking just yet.
