Followed a link Nog posted below to the ural site.

 

If you are bored ther is a laugh a minute in here.

 

For example, regarding the sump issues.

 

Before you pick up a spanner-look under the engine at the sump, if it is a pressed steel one- only a couple of inches deep- that is your'e first problem. These engines are air/oil cooled and require a vast amount of WARM not Boiling oil, especially for the left hand piston- which is why it has it's own oil feed in the cylinder.

Take the sump plate off and slit round it with a hacksaw blade held in a rag and weld in a strip of steel four inches 100mm deep. This will give you a reserve of about a gallon of oil. If you have a cast alloy sump, buy a steel one and do likewise. The welding of the sump will distort it and you will have to use silicone gasket goo to make a good seal. Use builders merchants silicone sealer- it's the same stuff as in the bike shops. By the way, fit sump and engine sepperately, you won't get them in the frame together.This modification will do the most for reliability especially if your Ural / Dnepr likes to drink and so will you after all this

 

And on carby balancing,

 

 

Now, if you don't know the method for Ural / Dnepr carb balancing I had better tell you as it is crucial to smooth running and reliability, more Urals have popped because of this than anything else. It is a much more accurate method than any other. Warm the bike up, 10 miles at least, put it on the main stand and run the engine in top gear, lock the throttle with a clamp so that the speeedo reads 45-50mph and short out one cylinder with a screwdriver or remove the plug cap, if the engine dies then open the carb on the cylinder that wasn't shorted out using the throttle cable adjuster. Then repeat this procedure on the other cylinder. You are aiming for the bike running evenly and at the same speed which ever cylinder is shorted out. This method relies on the spark plugs being in good order -don't mess around, buy new ones (........Charles)

Now adjust the slow running tick over screws to finish the the job, this method is more accurate that stethoscopes, vaccum gauges or bits of rubber pipe so don't go wasting your money. The later Karburettorskis are pretty good, but if you had earlier ones like me, get Mikunis or Amals and make up adaptor plates to get them to fit.

 

Viva la moto guzzi.

What are they talking about? If the oil doesn't boil, the french fries get soggy <_>

I wonder if the tool kit comes with a welding torch?

Good for making the fries extra crispy :food:

As an ex-Dneprist myself, and it was an old and skanky example that needed ether to go from cold, these are not as bad as the owners like to make out. The myths however are useful, along the lines of "only real men ride Urals" and "alternative lifestyle".

 

You will never find a girl on a Ural. This is not because a woman couldn't ride one, but because women have a minimum threshold of common sense that is too high for Urals, and don't like to smell permanently of used oil. Though having said that, an ex-girlfriend used to ride a 2 stroke Neval........
