Engine Serial Numbers Question
Regarding 2C69069H3, as I said earlier I have a photo of it as an alleged engine VIN and I already mentioned one of the problems with it. Why is it on your latest chart?
I dont have photos of most of the Shovelhead and Sportster VINs you just added. But I do have photos of 2A18165H3 and 2A21995H3 as alleged engine VINs. Both appear to have problems. Why are they on your chart?
Another alleged engine VIN I have a photo of is 4A21000H2 but it too appears to have problems. Why is it on your chart? And there also appears to be a problem underneath the R-H case where the crankcase production number would normally be.
As I said a few days ago there is no point recording VINs for your chart unless they appear authentic.

You have 100% valid and fair questions.
I don't...can you offer any factory data? Such information would really help our research. I suspect all that factory data is locked up in some rich collectors safe, or maybe published in a book that cost $500 or more! So for now, all I have is each other's experiences.

I would like to start such NOTEs using your information...I will work on that this morning. This is extremely time consuming and constant changes and corrections are needed.....especially my SPELLING!!!
Thank you for your productive participation.

I would like to start adding such inaccuracies or concerns to the chart. I would like to start with the VIN's you mentioned avove.
I am listing each VIN and would like to you to clarify in detail your thoughts on each VIN
THANKS!!
2C69069H3
2A18165H3
2A21995H3

I do not have 4A21000H2 listed on the chart...I just added it and will await details from you. Thanks

This example is for the reported concern for the accuracy of 2A18165H3. Let me know if you can not make such comments and I will fiddle with the settings to see what can be done to accessible to others.
IN ORDER TO SEE THIS OPTION ON YOUR PHONE...you may have to download the google sheets app.

Same thing applied to 1973 Sportsters because the 3A and 4A are in the same family as each other.
But while were on 1973 models there is an alleged guide called Motorcycle Identification copyrighted 1986 by one Lee S Cole. It indicates VINs 10000, 10001 and 10002 for 73 Shovels were assigned to FXs while VINs for 73 FLHs began at 10003 and VINs for 73 FLs started at 11791.
It also suggests VINs for 73 Sportsters began at 40001 and 40002 depending on model. But what about VIN 40000 for 73 Sportsters? The guide doesnt say, even though VIN 40000 is mentioned in Service Bulletin 656.
And was 11791 really the lowest VIN for a 73 FL? I do not know. One of the problems with the guide by Mr Cole is that we know for certain that it contains a lot of errors regarding 1970/71 and earlier, including some that are exactly the same as those in a certain booklet used by the CHP back in the day. And therefore I am reluctant to believe anything else the alleged guide from 1986 says.

As I mentioned earlier I have a photo of 2C69069H3 as an alleged engine VIN. The C and H are what I refer to as wide and that’s what I would expect. Also the 6s are the type I’d expect, at that stage of numbering. But only one of the 9s is the type I’d expect at that stage of numbering which of course suggests that something unusual was going on with the other 9.
Regarding 2A72931H3, at Mecum I see nine photos but I can’t read either VIN. BTW, notice the lower R-H rear forging number may be 47652-73. If so it indicates the frame is later-73 or later.
From your list of E-Glides the only one I have photos of is 2A14556H3. I can’t see anything wrong with the frame VIN characters and they appear consistent with factory stamping. These include what I refer to as a narrow or slim A, 4 and H. And a rounded 6. I can’t see anything wrong with the engine VIN characters and they appear authentic. These include a wide A, 4 and H. And a rounded 6 which appears consistent with factory stamping of engines at that stage of numbering.
I have photos of 2C21433H3. Engine VIN may be okay but stamped above it is another ID number although I don’t know what it indicates. I’m not convinced about the frame VIN, partly because of the moulding.
Regarding the bike said to be 2C21775H3, notice its battery appears big enough to handle electric start. Originally the 2C (FX-1200) had a smaller battery because that model was kick-only. For Super Glides the electric starter is generally thought to have been introduced for 1974 models and the model designator was 9D (FXE-1200). But a lot of pieces relating to an electric starter have part numbers ending with -73, including electric start conversion kit #33217-73, and I have wondered at times if the FXE first appeared as a very late 73 model. But I have no VIN evidence yet. In other words I have no evidence yet of VINs 9D+++++H3.
From your list of Sportsters I have a photo of engine VIN 4A44984H3. I can’t see anything wrong with the characters and they appear consistent with factory stamping. These include wide 4s, wide A and wide H.
As I mentioned earlier, for 1973 Shovel engine VINs it seems the factory swapped the characters used as the 6 and 9 around several times during that model year. And it appears the same thing happened with the characters used as the 6 and 9 for 1973 Sportster engine VINs. That is apparently why 4A44984H3 has a 9 which is not rounded.
I have a photo of engine VIN 4A61720H3 but it’s blurry so I can’t tell if it’s authentic or not.
Another post to follow.

The Best of Harley-Davidson for Lifelong Riders
THANKS!
The one thing thus far I find interesting in the pdf you posted is that for the 73' models...the book lists a total of all model bikes at 70,903...but the VIN on one bike found is 2A 72931 H3. I believe this may either be incorrect totals...or is correct, but proves that the a single sequential number list ran across the board for all models, including the Golf Carts. Probably the same with other years as well, just ain't got there yet!
