Bike numbers.....
I need some help with all these different numbers on my bike. The title says 1999 FLH spec-constd. It has a VIN tag on the frame that is what the license and insurance used. But it has a lot of different numbers on it that I have not been able to find out what they mean. The motor is a shovelhead with 19209276. The rear swing-arm has 47606-58 on the right side rear. The frame has 47651-58 on the part below the shock bolt. Does anyone have any idea?

The motor number (if is a Harley shovel,) the "76" of that number might be the year of the bike that the shovel motor came from 1976. (That motor number looks a little long to me for HD however.)
And the bike was inspected and titled as you have it now in 1999.

Ok, so you have a California blue tag. You are good to go, that tag was applied as a replacement or assigned VIN by CHP and DMV.

You have a 'bitsa' bike aka Kali special construction. Starting in '70 MoCo staring matching frame, motor, and title. If anyone one of the three were missing, it could get the SPCN status.
That long number assisgned is just a number assigned by CHP and DMV. The last 2 digits do not mean it was initially a -76 motor or frame.
That number on the swing arm is a casting number. There were 4 types of swing arms that were used from 1958-1972 and all ended with -58. So the fact that the number ends in -58 will not mean it was first available in 1958. Is the swing arm round or square? 1972 was the last year for the round swing arm.
Identifying your frame can be done once you identify the forging and die numbers. And 1962-70 frames used a security code on the neck area to help identify the year as well.
Identifying your motor can be as easy (or not) as looking at the right case infront of the front tapppet block (1970 to 1980). 1981 and later had the number stamped on the left case just below the rear head. And of course there are exceptions. For a couple of years MoCo decided to bury the motor vin inside the right case. You can only see it by removing the front tappet block (my 1975 FXE is just that way). Once you have the number you can find out what your motor started life as.
Cylinders, heads, transmissions and such all have casting numbers that can get you close to your year and model, but you must keep in mind that the casting number might be the same for several years. MoCo even took the time to stamp some componets as well with a date code.
Best part though is that you have a clean bike with a clean title and means you will not see your bike being towed away because of funny numbers.

Rich, welcome to the forum. I thought your engine number may not be H-D and I just looked at your other thread. Notice your R-H crankcase has the letters STD cast-in. STD is an aftermarket manufacturer. Has the left case also got STD on it, maybe just below the cylinders?
Is there anything stamped on top of the cases near the rear engine mounting bolts? In your instance you may find 2092 stamped there? If not, is there anything else there?
Forging number 47606-58 on the R-H side of the swingarm was used for 195872, although its possible some early-58s had forging number EX2039 which indicated a prototype swingarm. Near 47606-58, is there another number?
On the left side of the swingarm, are there any numbers and/or letters? A photo of the left side would also help with ID. There were at least ELEVEN different round swingarms for 195872 although some differences are very minor.
On the frame, forging number 47651-58 was used on the R-H side for 1958 models through early-1973 models. However, the R-H side of your frame appears to have a two-hole block welded on to accommodate the bracket for the passenger peg but the block wasnt original until about 1977 models so Im not sure whats happening there. Can you post a close-up please.
On the left side of the frame you may find forging number 47654-65. Can you confirm that, or is there a different number there? Thanks.

84's had the number on the left case, and 4 stars on the right case where the numbers used to be.

Here are some off the pics I have already. I will go get some more when I get back in town. Yes, both cases have STD on them. I do not remember anything on the left side of the swingarm but I will look again. But in one the photos I can see some sort of number near the rear motor mounts.
