The XZ world is more complicated than I thought

[XZv2]

Hi, all,
years ago I bought an XZ550RJ that had been sold new in Canada, imported secondhand in Holland; engine and frame# are 11J-000426. RJ and 11J are easily understandable. All XZ550 sold in European countries were model XZ550 or XZ550S and all have model code 11U and engine/frame# starting with 11U-.
This week I obtained a "Genuine Yamaha Service Manual" on the 550 RJ and RK models. The book was published in Feb. 1986 by Yamaha Motor Corporation USA in California.
To my surprise it starts by mentioning that the model code of the XZ 550 RJ is 11H and the the RJ frame/engine-numbers start with 11H-000101 and that the RK engine/framenumbers start with 11H-100101.
I cannot find in the part of the manual on the RJ any mentioning of the different code (11J) for the Canadian bikes.
In the service manual for the European XZ are listed different versions for different countries, such as lower camshafts for some models sold in Germany.
Are there differences between US and Canadian RJ's except model codes and frame/engine numbers?

Not sure of other differences, but the speedo on US models has both MPH & KPH scales with the MPH more prominent.  The Canadian speedos I've seen have just a KPH scale.

Yes, H2O, my Canadian bike also has only kilometers.
It is so strange Yamaha used the 11H code for the US RJ bikes and the 11J code for the Canadian RJ ones.
Perhaps it has to do with the capped-off non-adjustable pilot system of the US bikes that made them a class of their own.

At the time, US emissions laws were fairly new and being strongly enforced.  Some of them even made good sense.  Yamaha may have designated  special model numbers to differentiate the final destination for their US bound bikes, making it easier for inspectors at the point of import to check them for compliance.  It may even have been a rule from the Environmental Protection Agency or Department of Transportation that US models have a unique identification.

Thanks for the reference XZv2, I'm wanting the 11U clutch/primary gearsets then.
Is "Haben Sie einen vollständigen XZ550 primären gearset zum Verkauf, der Kurbelwellengang hat miteingeschlossen?" a reasonable request for the european gearset or do you have a better translation that I might use to inquire to the sellers on Ebay.de?

Gratefully,

i dunno.... i was wondering if there was 2 differnt speedometers that they had cause iv seen pics of em going to over 100 mph and others( like mine) only going to 80??? or sum thin like that... what did the different speedos mean???

[ColinthePilot]

my speedo goes to 140mph and tach redline is 10,000rpm(thats probably standard)

[h2olawyer]

The 83 US speedo shows up to 140 MPH.  The 82 only goes to 85.  (I can turn mine up to 11.  ;D )

The Canadian speedos are in KPH (US are large MPH #s & small KPH).

Haven't looked at any UK, So Pacific / Asian or Euro versions.
