Customer Question

Ural, Patrol 2007. My Ural dies when coming to a stop. I have cleaned the carburetors and had them sinked. The air filter is clean. I always use Shell or BP premium fuel and add sta-bil to the fuel. When it does die I have to choke it and/or crank the throttle up. it takes about a minute before I get it to fire up again. I have checked the fuel lines and when stopped in my garage I am getting fuel flowing through the lines.
I also put new spark plugs in the bike.

It sounds like it is running too lean.
This might be caused by vacuum air leaks around your
carbs or intake manifolds.
Try some B12 spray or starting fluid sparingly around
the carbs to see if the engine RPM's go up.
If they do then there is a vacuum leak.
Also check your carb clamps.

I tested for a vacuum leak and that was not the issue. Thanks for the idea but I will have to keep looking.

You could try your fuel mixture screws at 2.5 turns out
Set your valve clearance and a slight timing advance might help.
