Ural Paranoia Strikes Again

Post by Rusty Nuts » Sat Feb 29, 2020 6:19 pm

As you can tell I is new here and there are only a handful of know Urals within a days drive so "phone a friend" is out. I have about 200 miles on mine since the break in servicing was done (dealer provided) and it started making weird noises. I know, nobody else has ever heard anything unusual coming from one of these things :wink: . My deal is runs fine till it gets a few miles on it (30-45 minutes). it started the last time I drove it home from work. ran fine till I got close to the house then at mid to higher RPM's I could hear tapping from the motor. When I got home and parked, nothing. Took it out again today and found an empty paring lot about 15 miles from here to practice on 2 wheels (talk about looks) and had no problems. probably spent 30-45 minutes there and when I got close to home heard it again. Let it cool for a couple hours and took it back out, you know, to go get the mail :D . After 30 miles or so, same thing. Took some back roads home running 35 or so and the sound went away. Seems to only start if I'm 45 or over for a length of time. Still at the tail end of the break in period so it has only seen 55 for a short spurt or 2. Guess I should add filled up between the 2 occurrences so I am ruling the gas out. Unless somebody tells me what it could be, I will run it till it tells (or shows) me what it might be.

More than likely, the tapping sound is coming from your tappets (I make joke). Perfectly normal. Air-cooled engines transmit valvetrain noise much easier than liquid-cooled engines, what with their noise damping water jackets. If the sound makes you nervous, just unscrew the valve covers and check your valve clearance gap in accordance with your owner's manual.

Just for grins, double check your engine oil level.

Also, now is a good a time as any to check the tappets to make sure they haven’t become too lose or tight. A sticky in the maintenance section has a video on how to do it. It might be under the 750 or 650cc sections. Procedure hasn’t changed.

Thanks for the quick replies. with the score being 2-0 for the tappets, I'll start there until something else rolls in. Oil was fine, full and clear as new. My other bike is also air-cooled, although a different animal, she purrs like a kitten. May have to take her out tomorrow, think she is getting jealous.

Thanks again. It's things like this that make this place rock!

Correct, assuming your Indian doesn't have a large metal sound reflector/amplifier hanging off the right side, bouncing it's engine noises directly up to your right eardrum.

Make it 3.0, but I will note that while you can hear them, it should not change dramatically as the engine is run or at higher speeds.

Pull the valve covers and do the checks before you run it again. Possibles are too loose, a set nut loose or and hopefully not a valve train issue.

If its one of the first two you are likely fine. I have had diesels that were badly mis-set, once corrected, no more propagation (way too loose and you will find pounded iron in a brown color with the feelers)

The valve train noise is noticeably louder with the larger cooling fins and valve covers of the 2019's, especially with less clatter coming from the timing and alternator gears to mask it.

I've also been advised that because of the improvements in materials and tolerances, the valve clearances now tend to close up rather than open up in the break in period, so now more than ever, a sudden increase in noise is a good reason to pop the covers and check.

Hey rusty
You Ural has solid lifters
where you Indian has modern hydrolic lifters, so it will be quite compared to the Ural.
These Urals are the noisest sickles I have come across :lol:
So my advice is just ride it, if there is anything wrong it'll get much louder :o
You're welcome to ride up this way some time and we'll give it a listen :thumbsup:

Had me right up till I seen thunderstorms in the afternoon. I will check clearances in the morning and see what that brings. more to come. But if you are in Russellville, we will have to meet up for lunch or somthn. That's only like 2 hours in Ural time. An hour if I take the car.

You say break in service was done 200 miles ago, right? At the break in service the valves would have been checked and adjusted, and as noted above valve lash will tighten on new bikes, so they were likely loosened to spec during the service hence the increased noise. BTW, noisy valves are happy valves so if you check again make sure you don't tighten beyond recommended spec.

The OP indicates a pretty dramatic change in the first 45 minute of ops and over certain speeds with heat build up.

To me that is concerning. Having listened to a whole lot of engines over the years, it should not be that dramatic a change. A bit yes, its air cooled and they heat up.

The other thing is it should be checked cold and then when its gotten hot.

I had this once, one tappet set slightly more loose than normal, so more clatter, but either it was altered at the next service so it went away, or I got used to it, I don't know which. But whichever, I can't hear it anymore and nothing has broke or fell off. :D
