Hi,

Does anyone have a clue, why some PO should have placed a 'new' obviously not factory stamped engine # in the crankcase.
I guess it's done to meet with the chassis#, but for what purpose? Did all 1000 triples have numbers at the swingarmpivot, as well at the steeringhead?
Any info welcome.

Regards, Hein

obviously, the original number has been removed from the engine. A "matching number" combination is always a bit more worth than a non matching one. But doing it that unprofessional is nothing that increases the value I'd say...

I don't think frame-Numbers have been stamped at two places, but I am ready to learn...
 
Hi Lothar,

Well mine does have it's # at two places. Didn't the US market require a number on the headstock?
Bike is registered in Holland 1978, however probably build in 1977?

Just been curious, since I have this bike, why someone bothered with the numbers?
Suppose there has been put in an other engine, somewhere in it's lifespan.

I do agree, one could have used proper stamping equipment and done a proper job, this looks really fake to me.

Hein,

In Germany you need the frame number stamped on the headstock as well, or have an alternate location
annotated in the registration papers (i.e '70s Japs). My frame doesn't have the frame number stamped on the
swinger pivot, which leads me to believe that it's not the original frame.

Regards,
Gerald
 
It's just a lousy job of filing off the original number (can see the file marks) and an even lousier job of stamping on the "new" numbers. It's not hard to stamp clear numbers in aluminium, but this guy managed to cock it up  ::)

He obviously didn't have a * stamp either
 
New replacement frames have the provision for VIN at both headstock and LH swingarm mounting plate.  All that's missing is the actual serial number, the "1000/1" and/or "1000/3cl" are factory stamped.

VIN at headstock was mandatory in many european countries, swingarm numbering always included the italian DGM homologation numbers.  Frame and engine numbers always matched, so it can be rightly assumed the engine (or cases only) has been swapped at some point in time and the number changed accordingly, albeit rather clumsily.

USA market machines do have a number on the headstock in the form of an alloy plate held in place with rivets.
the plate specifies it to meet all federal standards in effect at the time of production.
number on the plate matched engine and frame until the advent of the mandated 17 digit VIN code.
somewhere between 1000*6900 and *7800 the stamping on the swingarm plate disappeared and the steering head was stamped instead. USA bikes still have the alloy plate riveted over the original headstock stamping.
