My name is Sven Peter and I live for 25 years in Costa Rica, 10°N,84°W at about 1350m = 4420feet above sea level.
Active member of USCA at sidecar.com from where I was sent to here for the Ural specific questions I have.
My Ural Patrol named "Sophie Travelair" is now my 3rd rig and 10th bike in 32 years.
I got Sophie in July2013 in Salem Oregon, went with her and my son up to Alaska Arctic circle and back.

Since 10 days ago I have her finally road legal in Costa Rica. (12.500km and the engine is still not free although I run on mineral oil)
Until today I wasn't happy with the jeting at all. As she ran nearly always way too fat (with original needle she nearly died on Mount Hood, Oregon due to overheating...spark plugs were white as brand new.)
I determined that Pilot jets are #65 and main jets #125. After mechanically syncronizing, opening the air screw to 2 turns , droping the 6 slot needle from Raceway to the 4th slot and changing to Super 95 octane, the behaviour improoved quite a bit.
Today I pushed her out of town up into the mountains until 2300 or 2400m = 7500 or 7860 feet on pretty steep roads and cold weather 18°C = 65°F and felt her finally runing better.
Cilinder head temps were in all conditions sane and still reasonably low. typically 130 to 165°C=265 to 330°F. For now I guess I am pretty OK, but above in the thread was mentioned a process for to adjust the carbs in the right manner.
Does anybody have a link to a good explaination of the process as in 32 years I never had to fool around with carb jets?
Our typical riding range is 400m-3300m =1300-10.800feet above sea level and temperatures are generally between 15 and 32°C = 60 to 90°F
If You think I am kidding, come down to ride and sweat here. I can give you good road hints.
Best regards from a cold front in the middle of our summer.
