'78 Planeta 3 white smoke problem..

Basri · 07-28-2012, 01:37 AM

Hi, i recently had a 1978 planeta 3 with sidecar (Russian IZH) and now ridng it after minor repairs.

Changed it from 6V to 12V with electronic ignition, runs well.

Recomended gasoline/oil ratio is 1:25, which is 40cc oil in to 1 Liter gas.

Even with 25cc oil / 1 Liter gas, having extreme white smoke from pipes.

I belive it can not suck sufficient air from the filter. Any idea how to clean that old type air filter with oil in it (oil bath) and what kind / how much oil i should put in it ..

or,

any other thoughts for that extreme white smoke ?..

Many thanks in advance..

On old air cooled VW oil bath air cleaners, you simply dump the old oil out, wipe everything clean and add oil up to the painted fill line. We use 4 stroke engine oil in them.

As for your gas / oil fuel mixture, we normally run around 40 to 1 UNITS fuel to each UNIT of oil. So......you have a 40 / 1 ratio of fuel to oil.

On very old and crude engines we somtimes go to 32 / 1 mixture. Todays modern oils do smoke less than the old oils from back in the day. Especially the synthetic blends. Some are even labled "smokeless" although they will smoke some till engine comes up to temperature.

Thanks Low Budget, i liked your nick..

Do you think it is a good idea to replace old oil bath filter with something lilke that ?..

It would likely do a better job of filtering small particles out, but may make your jetting wrong. I would first try to replenish the oil in the stock filter if all your rubber boots between the cleaner and carb intake are good, that way your jetting will likely be right.

Work from stock settings whenever possible to first get everything right before modifying anything, that way you know how to go back and get everything right.

Yes, you're right Low Budget, i'll go with stock fllter, i have put a new carb on it and don't want to mess with settings..

If the stock one is too bad, will buy a complate new one for 35.- Turkish Lira (19.- Usdollars) which will damage my 'low budget'

Stay with the 25:1 oil ratio.

I run Jawas 350s and 250s tens of thousands of highway miles here in the US and it sounds like your white smoke issue is quite possibly due to a leaking seal between your primary drive/transmission oil and the crankcase.

That is, if you haven't overfilled the oil bath filter tub...

Good luck.

Thank you planktone..

Now i am almost sure that is the problem because smoke s white, not blue.

Have to replace two of the crank seals soon..
