POWER AND MPG'S DROP AFTER A DEALER SERVICE

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.

POWER AND MPG'S DROP AFTER A DEALER SERVICE

Post by Urallove2017 » Mon Sep 16, 2019 9:16 pm

Any thoughts? My 2017 rig was get 40MPGS consitently and had good power crusing at 60-65 mpgs . Took it in for the 6200 mile service now only getting 30 MPG it can hardly maintain 60 MPGs.

Start with the simple, compliance fittings not loose, TBs balances, spark plugs screwed in, spark plug cables connected correctly, brakes not binding, air filter is present and the plastic was left on if new, wheels bearings not seizing, oil is not too full or too low, just take some time and go over it all. Or, take it back to the dealer and tell them to figure out why their service broke it.

Yeah, I sort of think there might be a lesson in this . . . about who does your service! (Hint: Urals are pretty easy to do yourself.)

Ask the dealer for an itemized list of everything that their hands and wrenches touched whilst your Ural was in their possession. It's a fair inquiry; couch it as information that you want for your own record keeping.

Then, after you have the requested info, drop the bomb and mention the radically reduced performance, which you are reasonably walking back to them as the cause. Ask them how they're going to resolve it, and wait for an answer.

For the MPG...

Did you get more confident riding it and now you twist the throttle a little harder and go a little faster?
The number one factor for MPG with a Ural is driving and accelerating slowly.
Get a little aggressive/sporty with the throttle and MPGs plummet?

For MPG and MPH...

Have you been doing more riding two up? I know for a fact that a monkey puts a good dent in both fuel economy and top speed.

Have you owned the rig since new? Did a previous owner/other dealer tweak the EFI map and Ural set it back to some other variation?

Outside of those, Harryball is right, start looking at the basics and make sure it isn't something simple.
Also, there isn't much that even a shade tree mechanic can't do on a Ural so consider doing basic service yourself.
Unlike cars, there are so many personalizations and preferences that differ from factory settings that I wouldn't want anyone else to mess with my bike.

2 Blind shots into the dark:
1- Soaked air filter (But yours should be a paperfilter, not one to oil like mine)
2- They might have set the valve gap to the factory settings 0,05-0,1mm (0,002-=,004"). If that is done with some carbon on the valves, then the valves do not close completely and soon may burn the valve seats...

... have done it myself once nearly.
I noticed it at time, made a carbon clean up with Marvel Mystery oil and set back the valve gap to the conservative setting I use to do: 0,125mm (0,005") go / 0,15mm (0,006") no go.

As my engine is actually open and shortly ago I had Medio Tico's engine open too, I noticed one strange aspect on both.
MT's Miss Peabody serviced until 7000km by book and shop and now at 13.000km needed a new cam. Exhaust lobes totally worn and intake noticeably. All Rocker noses badly pitted and needed reconditioning. 3 out of 4 push rods bent and had to be replaced.The 4 cam followers were worn and needed replacement.

My Sophie Travelair since new was set with above valve settings. Now at 43.300km the exhaust lobes are slightly worn = About 1/4th of Miss Peabodies wear mark width, but no worrysome depth. Intake lobes look like new. 3 Rockers have noticable pitting and were easy to recondition. Only one push rod is bent and needs exchange (will do all anyway) Valves need little retouch - mainly exhaust. The cam followers I will have to check still.

My plan now is to continue to use the intake gap 0,125mm (0,005") go / 0,15mm (0,006") no go.
But raise the exhaust valve gap to 0,15mm (0,006") go / 0,175mm (0,007") No Go.

May others judge if wrong or right. I go for health over speed.

Could be they messed up the valve gaps; does the tappet rattle sound normal or different?

"A tappy valve is a happy valve."
Worry when you do not hear the valves.
That has been for over 80 years the saying of BMW riders.
