Hello,

I tried to reduce idle speed on k 100 8 v by central idle screw but it didnt react as expected. Then I tried with brass inlet screws. First cylinder almost no reaction, second same, third cylinder reacted instantly, fourth like first and second very slowly.
Anyone could explain why only one cylinder reacts? Finally I reduced idle with brass screw on third cylinder. All the time there is intensive gasoline smell on exaust. Could it be leaking injector? Maybe third?
FPR is almost new.

Nino,

The exhaust on my bike with the sidecar is always very rich and the exhaust always has a black deposit. Hopefully, I will start to work on it by the end of the week. (end of the winter in Canada). I will let you know what I find.

Maybe temperature sensor sends signal for richer mix?

This is exactly what is my suspicion and I have a new one to be installed. This as well as the air flow meter will be my first steps for troubleshooting.
Once the sidecar is re-installed, the space to access the air box and temperature sensor is very limited and this is why both device will be replaced before having the bike on the road.
The snow is almost gone and I am anxious to be riding again.

Mine MAF doesnt react on bypass screw. Engine runs even with a totaly closed vane, but performs well. Consumption is little bit higher

There are two things I would do first off Nino.
Check the SPs. If one is wet then its probably that injector leaking but I doubt there'd be enough fuel to smell it out the exhaust. If all are wet then I'd be first looking at the sensor (test pins #10 & #13 on the FICU plug) or try swapping the FICU itself with a known working unit. We've seen a few failures lately and over fueling seems to be a symptom.
Just my thoughts mate. Cheers

Thanks Bert and Holister. I have a plus FICU in garage but from swiss bike which was electronicaly  limited to 6 th rpm. Bay the way is there a possibility of removimg FICU blocade

I was wondering if it's the FIcu or the Icu that lock the RPM at 6K max. In my opinion, it was the ignition computer.
I started the ETK and checked both.
For the fuel injection unit the only option is "official vehicles" when for the ignition unit, the option is "Switzerland version?"
This leads me to believe that I am right in my assumption that the rev limiter is built in the ignition unit and not the Fuel Injection.

I am not shure but I think its black box in the head of the frame. I tried swiss bike K 100 and it was limited to 6500 rpm, with red mark on rev counter. 
I swapped that black box and suddenly same bike went to usual limit of 8700 rpm freely. So FICU or ICU? What is it

This is the Ignition Control unit (ICU).
What you may want to swap first to solve your problem is the Fuel Injection unit(under the seat/tool box.

I have one, will try. in the meantime chaged temp sensor this afternoon. Also used one but I saw some improvement. Not so much smell from exaust any more.
