Background: Fiona's speedometer needle had gone into "windshield wiper" mode at the start of the last cold snap we had a week or so ago. And while it still kept mostly accurate record with the trip meter and the odometer, I'd been forced to use an old iphone4 as a GPS speedometer.
This arrangement allowed me to verify what the odometer was displaying in the old speedometer was mostly accurate.
Kilometer reading on the old speedometer
It only took a few minutes for me to remove the old speedometer (and managed to do it without dropping the small nuts that hold the speedometer bracket in place, into the rats nest that is the headlight bucket).
Installation of the new one was straightforward as well. I put the headlight back on, geared up and went for a test ride. The new speedometer works very nicely and matches the GPS pretty closely from what I was able to see during the short test ride.

I had thought, instead of using the old iphone, to use Martha's TomTom GPS that we'd bought a while ago for her car. She doesn't use it anymore, preferring to use the Waze app on the iphone.
We'd used a similar sized GPS unit while renting a rig in Ireland this past summer and I'd liked the waterproof case the rental company provided with the rig. So I bought one via Amazon:
This TomTom XXL is a nice unit but I discovered after I bought the case that it doesn't have a trip meter! I mean really, every GPS I've ever owned has one to record mileage driven, why not this unit?
So, I won't be using the TomTom, for speedometer/trip meter functions. Just for navigation perhaps on trips.
The case though, will hold the old iphone just fine for those rainy days.
I'll keep the iphone GPS mounted for a while longer to gauge the accuracy of the replacement speedometer, then it'll go back into storage I think.
Scarlett Update: Randy of Unique Rides has pulled the engine from Scarlett, now waiting on word from Ural in Redmond as to whether to ship it whole to them for analysis/repair or just the engine case minus the jugs and such.
