I recently changed the oil on my bike, and put some gas in it, and it is blowing black smoke every time I start it up.

What can I do to adjust this or will it burn off on its own?

Thanks!

I got it changed at a dealership....

They used 10w40 performance oil.

I assume that they put in through the oil cap.. where the oil is supposed to go.  I double checked the oil amount in the oil level look through and it is slightly covering the look through on the kickstand and  i can just barely see it when i have it level.

I know i was having some piston noise before I took it to the dealership.

Also according to them, the valve adjustments are good.

I am more so worried about the black smoke and the piston noise.

It's owned by a family friend and it was done for next to free in less time then it would take me soooo.

okay.. I will req the numbers but chances are I wont see anything till Monday as the shop is closed for the weekend now.

Maybe I am going down the wrong line of thought......but I always felt that burning oil made bluish white smoke and burning fuel made black smoke.

Did somebody leave the choke on?  Is the original vacuum petcock acting up and bleeding fuel into the suction hose?  Is it time for her to "Check her Petcock"?

Time to pick a single path and follow it or else you risk confusing the new person too too much.

Making sure the choke button is in all the way is something they can do right away.  That is a no brainer.

Oil on the air filter paper can cause extreme richness as the stock paper filter won't pass enough air if it got oiled by accident (or on purpose by Mikey with his little spray can of K&N filter oil).

Problem is that he/she has let a dealership Mikey work on her bike and there is simply no telling what they did to it in misguided attempts to service it.

We don't even know that it was a Suzuki motorcycle dealership (not that it makes a lot of difference, really) -- all we know is it smokes black smoke now that it has been given back to him/her.

And you are right, we still don't know year model, mileage, or any of the other things that would be useful.

So, we are playing "Boy George in the bathroom with the toilet plunger" again .... and we know how Nurse Ratchet and Colonel Mustard both feel about 'ol floppy hat George boy a' messing about in their bathroom when nobody is about, now don't we?  

In this particular game of Clue we aren't being given any information at all so we can play.

Kayleigh, talk to us, talk to us LOTS, tell us all about your bike, tell us how old it is, how many miles, how you got it, who has worked on it, that sort of stuff.   Why is it you think you have a piston issue?   Did someone tell you that?

If you paid those people to work on your bike and they gave it back to you all screwed up like they did, then the Service Manager should make that right at NO CHARGE to you.

I'm with OF, Gyrobob, and Dave.  I've always been told Black smoke is fuel, bluish white is oil, and really white is water.

Check the enrichment valve(choke). Make sure it is all the way in. Do the petcock test to make sure there is not a problem there. Check the paper air filter element.  If it's covered with oil, it'll choke the engine causing black smoke.  If so, replace it after figuring out where the oil came from. If it's an oilable pod or oilable stock replacement, it could just have too much oil.

We are assuming there was no problem like this before the oil change.  Did you have them do anything else to the bike while it was there?  Are there any signs that they did anything else while it was there?

It would be helpful to know year, miles, any mods done, any problems apparent before oil change.

So I checked all the valves and my "choke"

I have the fuel tank on reserve as I need to get some gas

The choke is all the way in

I can hear some piston noise

I am getting a lot of shaking and a rattle (more than usual). That started happening last week. It started on my way to work.. I was blasting about 70 on the freeway and I started losing power, as in I was holding the throttle steady and it started backfiring and dropped to 60 mph. I pulled off did a few checks put some gas in and it seemingly worked out okay, but then I noticed I was low oil when I got home later that day So I added some oil.. and kept adding and adding until I had a view of the oil in the oil level sight when i had the kickstand down .

There are no signs that the did anything else while it was there

I did have carb rebuilt after I got the bike. I got at it at a garage sale for $500 bucks knowing it needed about $500 of work on it.

I haven't got a chance to look at the air filter yet..


BUT on the flip side I ride a 05 s40 with 9k on it.
