2-stroke ped + smoke

[Claud 14.7 to 1]

Hi, I have a ped which needs to be sold.

It has 7,200 miles, but the problem is it smokes alot. Manly on start up, and after about 5 mins riding the smoking becomes significantly less.

Now is there anyway i can stop it smoking in the short term, ie just for the buyer "check over". After that i dont mind. It doesnt have to be long term thing. The rings are probably worn, but there is no way im going to change them...

It runs perfectly, just smokes.

Any addivtes or such like??? Whatever you recon.

Thank you!

You could try the old chestnut of warming the bike up before any prospective buyer comes round, but to be fair you should let them know of any problems they might encounter if they buy the bike. Or you could just leave it and try an baffle them with science " two strokes always smoke when starting up" etc

the smoke is a good sign, if there was no smoke at start up it would mean there was no oil beening burnt and that would be a problem

Hi

It is a 2 stroke. The rings are going to do nothing to stop oil getting burnt and smoking as the oil is coming in with the air and petrol.

Possibly the air filter is dirty (will richen the mixture). Possibly the carb is leaking an dripping fuel into the engine when parked. Possibly the oil pump is set up too rich.

All the best

Hehe, it smokes alot. I think i'll take a picture to show you when i can be bothered.

Its a thick whitey/slightly bluey smoke. I know thats what they do, but i dont think this is normal. Plus it got noticeably worse after the winter months...

I told my bro to let it warm up...

[Ste]

Two strokes smoke, it's when they are not making any smoke at all then it's time to worry. Don't start the bike up before they get there, most people are wise to "I warmed it up for you" as the only reason people do that is to hide a problem starting or warming up.

[Claud 14.7 to 1]

Ok well i'll try Kickstart's suggestions. It did smoke before but this is just silly/embarrassingly smokey.

Thanks people.

Im probably completly wrong, but I was told that white smoke could just be condensation in the exhaust coming out as the bike warms up. My old Ped does this quite badly, especially in damp wheather (could be the crap weather which has made it seem worse). My two stroke bike also does this when it's started, left idling to warm up, and then the throttle is opened after a minute or two, resulting in loads of whitey bluey smoke being chucked out. Doesn't really do it so much if I just start riding as soon as it starts, or if I start it once it's already warm.

Just a thought, whatever it turns out to be, loads of peds do it so I don't think you have anything to worry about .

Well yes a little white smoke would not be so bad, even an ammout of any colour snoke smoke would be ok, but there is something amiss on my ped, i think...

Im just doing cosmetics at the mo, ill test the bike a bit later on.

[MarJay]

Two strokes Smoke... simple.

They have what is called a 'total loss' lubrication system whereby the oil is burned in the fuel. There is no 'engine oil' behind the rings that might escape into the cylinder... its all going to be burned anyway.

Blue smoke appears on four strokes where engine oil is being burned when it should not be. This can happen when the rings are worn etc. I can't see that blue smoke would ever be a bad thing on a two stroke however, because as I said above you /want/ it to burn the oil.

Also may I suggest trying to use a 'low smoke' scooter type two stroke oil? It definitely won't do the bike any good, because I hear the low smoke stuff is rubbish, however it might help you to reduce the amount of smoke that is emitted.

It seems that this would be a wasted effort if the buyer comes /expecting/ the bike to smoke!

Put redex in bike, cleaned air filter, and cleaned up the carb up a bit. It runs a bit better.

Still starts with loads of smoke when from cold. Not how it used to be. But runs nice when its warmed up.

Should be ok. May get some of that low smoke oil, thanks Marjay, or get some decent synthetic oil. It needs more oil anyway...

Cheers

don't know about peds, but my dt125 and other Auto-lube 2 smokes have an oil pump that is adjustable ( runs off the same cable as the throttle), perhaps the cable has worn or it has become mis-adjusted. The manual should tell you how the check it/re-set it.

This is the most I could get my ped to muster today when warming up, how much worse is it to this and is the smoke the same colour? That blue smoke is just two stroke, it has in the past chucked out loads of white smoke (which I just took to be condensation). If you want a pic of really bad two stroke smoke pollution, just wait until I get the KH back! That really puts everrything to shame!

is the bike a gillera or a Piaggio?

if it is, they are prone for getting damp in the exhaust, underneath by where the exhaust attaches to the barrel there is a bolt in the exhaust its self, i think its a 13 mm.
take it out and start her up, block off the end of the pipe so the fumes are comming out of this hole and it will sputter any water out through here...
also my friend has a stalker and it does smoke more in the cold weather. its normal, (and his smoke is white too) what oil do you use?

All the best

[binge]

Correction, i didnt see that u stated its an AP 50...
but still have a check for the little sump bung at the bottom of the exhaust just incase...

i wouldnt worry about it. just blag it off to the buyer saying its a two stroke and the oil mixture is high because that way it is safer as the engine wont seize!

Good Luck

Its probably even smokier now you put redex in! It doesn't help as it doesn't benefit a fairly modern engine.
As everyone else has said, 2 strokes smoke a lot, more so with an auto choke, hence it smokes more when you start it. As long as it doesn't smoke heavily once its been running a bit then its not a problem.

Dave

[Claud 14.7 to 1]

Less smoke after redex, i will continue to test tomorrow.

Its just it will look a bit wank if someone comes to look at it, turns it on and the whole premisis gets fogged out.

No joke

[divuk83]

That all redex does is make smoke, much to the disgust of my garage I put some in and I absolutely smoked the whole place out when it was on the dyno

Dave

[Claud 14.7 to 1]

Na, i put redex in the Honda all the time and it loves it, perfect.

Ped likes it also.

I like it too, tastes like cranberrys.

[ts50x0]

are you having a girraffe. that is not a lot of smoke for a 2 stroke. in fact its probably not enough. if i went to see a bike and it didnt smoke then i wouldnt buy it. the more smoke the better.

[Smoto Bob]
