How smoky should a 2 stroke be?

**SMOKEU** · 6th April 2012, 17:54

My TS185 blows very little smoke, and even in the power band people who have followed me say that they can't see visible smoke coming from the exhaust but they can smell the 2 stroke oil being burned.

If I give the bike a bit of a rev up in the garage then it will have a strong smell of 2 stroke in the garage. It's running on the oil injection system at the moment.

So how smoky should it be?

Smokey while its warming up, but not noticeable when its up to temp right?

I replaced the spark plug with a new one about 7 hours of riding ago. I went into a Suzuki bike dealership with the frame number so I'm sure it's the right plug. When the engine is cold it smokes a fair bit, although not really while warm. Here it is after a reasonably hard ride today:

All the 2 strokes i've owned have been smokey cold then clear once warmed. Unless they had issues. It sounds like yours is fine.

i had one of them as a first bike in 1975, dont remember it smoking to much, unlike a rd 200 i owned

Yours looks good man.

You don't know smokey until you ride my 2-smoker. Has problems at the moment..

To check the pump setting on a Suzuki...
((((With the motor not running)))
hold the throtle full open... theres a mark
on the pump arm that should line up with
a indexing mark on the pump body at full throtle..
If it dosn't adjust the cable at the adjuster
where it comes though the side case...

Edit............
If it a early model...
theres a screw in the carb where the slide goes..
take it out... open the throtle till you see a mark/indent
on the slide though the hole..thats the point the pump marks
should line up...

FFS, it's a two-stroke, they're so 60's.

Dump it and get a bike with a real motor..

More than 2 strokes is masturbation.

something thats not yet been mentioned is what fuel and oil you are using, Id expect dirter if unleaded, and if ya using a syn oil Ya wont see sfa smoke however if ya using a old school dyno oil it should be puffing all the time, thats a near perfect plug if its a well tuned race engine on avgas and syn oil.

If you were going hard for a while and shut it down straight away it looks ok.If you shut it down after riding slower then its a bit to grey.
Looks like 40/1 when should be 30/1 approx if it was a premix.
At least if it was 2 much oil all you would get is fouled plug and less power but to little becomes a big problem.

I followed the GF yesterday, her on a DT, a was very happy tootling along in her fumes.

The DT will puff a bit of smoke when cold but runs clean on the road. I had to use some shell oil from the garage which smoked quite a lot, very noticeable if I was doing some slow, trialsie stuff then opened it up. The bike left a big cloud of smoke. I'm back onto agip castor oil now & it runs much cleaner. I noticed no smoke at all yesterday after the initial warm up.
