Hi looking for some help identifying what year and size of engine i bought. As there is some conflicting information. The number stamped on the left side of engine is ☆2H40**9H9☆ left two middle numbers out for security reasons. As far as the research ive done its a 1200 cc out of a 79 flh. But on a 74 ci i read it should have 10 cooling fins on the jugs mine has 9 wich would make it an 80". I had the heads off and the pistons have .040 on the top so would this be a 80" .040 over or a 74" .040 over. Any help would be great.
Ok thank you i will measure while I have the head off. If it is a 74 .040 over what would then be 1240ish cc. Also am i right about it being out of a 79flh with those numbers.
I did a quick google search and the 2H & H9 indicates its from a 79 CLE sidecar. But I'm no expert for sure. Someone else will give you a better answer. I read somewhere that 79 was a strange year for serial #'s
The H9 translates to 1979, and the 2H indicates CLE, but there's a discrepancy... The factory manual says the 2H should be followed by 5 digits starting with 8. So the case number should read ☆2H80**9H9☆.
As mentioned, the '78.5 and '79 bike numbers tended to wobble from true...
There is no way a motor will have a CLE number on it. Look close at the numbers and make sure they are legit. Harley used strange number stamps. Here is what they should look like.
