Maybe just me but idling or running... all sounds pretty normal to me.
:thumbsup: Agree, the idle maybe set a tad low.
My 2 cents, John
The Ural's made Maine a much bigger state.

Only so much comes through in video, but from what I can hear, sounds normal to me. I'd say you might want to adjust the valves and maybe bump the idle up 100 RPM or so and check/balance the throttles.

When you do adjust the valves, check the rockers for up/down motion. I had a 2010 Patrol that had a bad rocker, moved up/down about 4mm and contributed to the harsh sounds from the right jug. New rocker cleaned it right up. Some movement is normal, 1 or 2mm at most. But my bad rocker was obviously not like the rest.

Otherwise, ride, break, fix, repeat.

Hi Harryball , I have set the valves to 0.10 mm as the manual says, when you say check the rocker movement (1 or 2 mm) what do you mean? (sorry but I'm a mechanic rookie)
Thanks

2006 Tourist, the gap should be .004 to .005. so did you mean .1 to .2 mm?

The rockers ride on a shaft as they happily rock away. On that shaft they can also move up or down slightly. Perpendicular to the rocking motion. Grab one, wiggle it up/down and see how far it moves. They should move a little, not much. That is what turned out to be the cause of the hard random ticking sounds from the right side on the 2010 Patrol.

If you did set the gap at 1 to 2mm, you might want to check that manual again and tighten them up.

Tha valves clearance is 0,10mm or 0,004 inch, so we both are right :wink:

Maybe a flush out of the final drive and replenish with the best (for your year) gear oil to see if that quiets things down. Just my 2 cents.
