'78 vs. '78 1/2 - How to tell?
Thanks,

Chrome won't get you home, but I bought it used.

1. HDs have a frame number and engine number which were identical.
2. Frame numbers are generally located on the left or right side of the steering head stock on the flat surface of a raised boss.
3. Unique die stamps are used to stamp the engine and frame. These numbers are protected by a star before and after the numbers.
4. The engine numbers are located on the right engine case on a raised boss.
Vin should look something like this...*1A 1000 H8* defined as follows: *(star) 1A (model) 10000 (sequential production number) H (mfg by Harley) 8 (1978)
A little more on model numbers..1A (FL) 2A (FLH-1200) 3G (FLH-80) 2C (FX)
A little more on production numbers (first is starting number; second is ending number)..
1A 18625H8 to 1A 71081H8
2A 10001H8 to 2A 79643H8
3G 10878H8 to 3G 79676H8
2C 10002H8 to 2C 78051H8
I think (if I'm wrong somebody plz correct me) that for 78, only the FLH go the 80 in motor. My book on production numbers only shows the FX-1200 (includes FX, FXS, and FXE) in 78. It shows that Fat Bobs and Low Riders were not available in 80 in configuration until 1979 (which had different model numbers/production numbers).
Question #1...Not sure what the cutoff on the production numbers were that separate early to late 78s. Notsure if there is an obvious change, butin mid-year changes in the engine included steel valve guides, new valve stems w/ hardened stems, new intake manifold w/ a single lip at the cylinder head that mated to new flat O-rings for better seal, and the ifgnition was changed to electronic.
Question #3..the kick start
Lots of folks retrofitted a kicker on their bikes, so that by itself doesn't mean you have an FX motor. Also another factor is the 80 motor. This was the first year for this. As mentioned above I believe the 80 for the FX line did not come out until 79.
Last thing, I do not have any info that I can find to say what the cut off number for production numbers was between early and late motors.
Sorry for long post. Dave
Thanks for the long post. You had good intel in there for me. I did realize that there was some detail regarding my bike that I failed to give in my initial post, some of which relates to your reply. In my research I discovered what appears to be three FLH variations in 1978 - 1) The FLH 1200 as shown at http://www.bikez.com/motorcycles/har...glide_1978.php 2) The 75th Anniversary FLH 3) The FLH 80. Both the anniversary an 80 models are mentioned here -- http://www.retrocom.com/retromilw/milwhd.htm. I guess it is possible that the FLH 80 and 75th Anniversary models are one and the same, but I think neither of those models apply to my situation. I have not seen on the engine any markings of engine size. However, the trim piece on the rear fender (which could very easily have been canibalized) clearly says "1200". Also, I checked the frame and engine case in the locations you mentioned and the VIN reads 9D*****H8. According to the info posted by Pococj in his response to a different question, 9D in the serial number denotes FXE, which was a 1200cc bike in 1978, which is denoted by the H8. The sequential production number of my bike is in the 11,000's, if that helps anyone else reading this who might be able to help me solve this mystery. I just received another piece to the puzzle, it would seem that the '78 1/2's came out after July 1978... Of course, that doesn't tell me anything regarding my production number.

Thanks again, this time for confirming my suspicions. I have come to the conclusion that I need to name my bike "Frank", after Frank N. Stien. Frank was big and powerful, well tempered, and assembled from different parts, but he didn't what he had. So he didn't know how to control them. I know I should probably name my bike after a woman, but Frank's bride was a horrible, heinous creature. I won't put that on my bike. Frank's better than that (keeping a galss half full attitude). The guy at the local indy shop says '78 bike (he didn't dispute the FLH claim) w/ '83 forks & '71 controls... oh, and the seat belongs to something that doesn't mount properly to my frame. After looking at a reply by Springer to another different post, I have almost come to the conclusion that I do not have a 1200 cc engine, because my cylinders have 9 fins. In Springer's reply he said:
[blockquote]... if you still want to identify what is was modeled around, then count the number of fins on the cylinders. If it has 10 then it would most likely be a 1200 and styled around 70-E78 1200 shovel. If it has 9, then it is likely to be a 1340 or L78-84. [/blockquote] If I did the math correctly, 1340 cc's is roughly 80 inÂł. Not that I am at all complaining about what I have. In the short time I have had it, I am thoroughly enjoying my bike, and I fully intend to give it a good home. (In all honesty I can't say that I will thoroughly enjoy the time spent working on it or spending the moeny to make it "right". I just wanna ride and ride and ride.) At this point I am just frustrated not knowing exactly what I have. I bought it through a third party, and it would seem that they knew less than I do.
Thanks in advance,

Never saw another one like it except on a shelf once. It was a 1200 with
electronic ignition and voltage regulator. It had a red logo which, I understand,
most bikers got rid of. It had the red 75 anniv. on the front fender & spoke wheels.
