Super High Oil Consumption; Next Step?

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

That'll teach me . . . checked bore size (78 mm) and ordered the 3 inch ball hone in silicon carbide. It's supposed to work up to 79 or 80 mm.

It might be the pic, but the oil ring sure looks like it is missing the top scraper ring. The oil ring is actually three pieces. I only see the bottom and the middle piece in the pic.
Good catch.

Update: I cleaned up the piston, cylinder head, and cylinder. Pulled the valves to allow better head cleanup, then lapped them and reinstalled. Honed the cylinder using the ball hone recommended by Van. Put it all together with nice new rings from Heindl (these have ALL the pieces, not just 2 out of 3 parts of the oil control ring) and of course new gaskets. Took it out today for two hours and about 65 miles, my usual loop. It has less vibration (mirrors are more clear) and a bit more power; ran very well.

But the best part is that there was no discernible oil usage! I have become accustomed to adding most of a pint of oil after this length of ride. Right now I'm changing oil and filter, because with the amount of blowby that's been occurring, it didn't take long for the oil to become really filthy.

Thanks for all the help!

Super High Oil Consumption Next Step

If your bore checks in to the wear limits listed in your yamaha shop manual, then just hone and rering it. These bores will always have a slight amount of scoring from the break in; its no big deal. Its important to make sure the cylinder is not out of round beyond factory specs, or it will allways blow oil. <p></p><i></i>
