More Smoke on one Side


jkross

Recommended Posts

The right side (sitting on the bike) is smoking more than the left...in fact, it appears the the left side isn't smoking enough. Cold, warm, hot...doesn't matter.

 

It runs like a CHAMP. Compression is IDENTICAL on both sides. There's no funky smell or anything...just a lack of smoke on the left side. I basically just got the bike and haven't ridden at all...just up and down my street. I've taken it apart (everything but the motor,) cleaning, polishing etc...now I want to do some real riding. Can I just pretend it's OK and go riding...or do I have to do something about it?

 

I've checked the forum and seen only a couple threads on this...and wanted more opinions.

 

You guys have been spot-on with every question I've ever asked...so I'm turning to you all again.

 

Thanks.

could be right side crank seal starting to go.

 

a. I guess I'd know that if my transmission oil level dropped steadily wouldn't I? Guess I have some riding to do to test that theory.

 

b. That's got to be a serious job. Is this pretty do-able?...Something a guy can do himself? (I'm not a mechanic, but I have friends who are.)

Sorry I can't be of any help, but I'm experiencing a similar problem with my bike. The jetting is perfect, but my right side smokes to high hell, and has oil coming out of the pipe, wheras the left side doesnt smoke much at all. Same situation, it ran on spot, never fouled a plug, but the smoke was noticeably different. The bike is totaled now, but I'd still like to know what's wrong with it in case I fix it up.

Sorry to hear it was totaled. How long did you ride it like that? Any performance issues...didn't blow the motor or anything?

 

Did you get any help on the forum...or call a shop? I'm going to call a shop and I'll get back to you with what they say.

 

Thanks, man.

i would check your jetting to make sure it's not running lean. Are your plugs dark brown? What oil are you running? I know some oils smoke more than others. What ratio are you running?

 

Good idea...I'll check the jetting and try to figure out if the left side lean or the right rich. To be honest, I just bought it and am using the fuel that's in it - So I can't answer any of your questions. I figured it was the right mixture..but when I refuel, I'll err on the side of rich. I'm not concerned so much with the smoke on one side...it's not much more than usual from any 2 stoke...just the lack of smoke on the left. Or is that crazy? Who knows. But, thanks.

Are these stock silencers or aftermarket?

Many aftermarkets can be dissasembled and repackaged (it might have oil in the packing...burning off)... Stock cans can't be taken apart. Err....they can be taken apart, they won't go back together again...:)

 

 

Don't go over rich. Before you worry too much...drain whatever gas is in there. Get some good pump gas, mix it 32:1....and give that a shot.

 

It could be a few things. One carb dirtier than the other, someone put mismatched jets in it...or, the unfortunate...a bad crank seal.

Look at the plugs. Keep a very, very close eye on the tranny fluid and the level...

Might not be a bad time to change the tranny fluid since you just got it as well...

Great advice man...I'll do just that and check all those things.

 

One additional question..a buddy of mine looked at the plug wires and thought one of them was bad or had almost gone bad. I know you have to buy the whole coil to replace the plug wires. Could a "less strong" spark on one side, due to a potentially bad plug wire cause the additional smoke...cause it's not burning hot enough?

Yep...sure can. Either wire can go on either cylinder....

It's a good idea..once you ruled out compression, plugged fuel line, dirty carbs, etc.

 

It's not a first solution....merely a step in the process.

 

Keep in mind, if the once silencer is loaded up with oil/gas...it might take some time to burn that off...

 

As said, normally....if everything else checks out, it's a bad crank seal on the right side. It'll run...but, it's gonna suck in tranny fluid and cause big problems before long.

 

If the crank seal is leaking on the left side...it'll suck air behind the Stator and flywheel, causing it to fall right on it's face after about 1/4 throttle, normally....

The motor will be in my 2001 shortly, I ran it for about 4 hours of hard trails like this, which is by no means a good idea. My symptoms were a little bit different, so I started a new thread, so I don't crap in yours too. The stealership will want about 600 in labor alone to do crank seals, I suspect that my crank seals are gone.

Thanks for getting back to me about what the dealership said - I hadn't checked yet. $600.00 seems a little steep but I know it's an involved process - bummer.

 

I'm haven't had much time to work on it, but - I switched the plug wires (thought one was bad) no difference. I swapped the plugs...the one on the smoking side looked a little dark - it made a little difference...caused a little more smoke on the left side...same amount on the right.

 

Next step is to tear the carbs apart for a good cleaning...check the air adjustments etc...and, to ride. I'm going to take it out (for the first time) for a few hours and see what happens...keep a close eye on the trans oil level. I don't think it's been ridden in a LONG time....so maybe it just needs a good ride to blow everything out...(yeah..I'm sure that's it - NOT!) I just pisses me off 'cause it runs so freakin strong up and down my street...snaps my neck back...dammit!

 

Anyway, thanks for the info. Good luck.
