Tell us about the "J" part, not familiar with that.
Not many people are,even Harley-Davidson told me to start with that there was no wlj type made by the company.
And that somebody just stamped the j in the crankcase.
A guy i know overhere has a wlh and was told the same story.
But tru the years we discovered 5 more wlh's and he contacted H-D again with his findings.
after a while they came back to him with the story that there was a special batch made for the goverment in Holland in the early 50's and they where coded wlh.
this made us believe that the wlj could also be a special batch and after a while i was contacted by a restorer of old H-D's that he bought a batch of old wl parts and there was a wlj crankcase in it with a serial nr.that was 45 numbers higher then mine.
send a pic from that one and my own to H-D and asked them the same question as before.
the info i got back from them was that there might have been a special batch made for the Japanese goverment(it was just after the ww2)(my original tombstone taillight has Harley-Davidson on top and made in Japan at the bottom)
as my bike was imported in the Netherlands back in 1984 from indonesia(former Dutch indies)as a former police bike there could be some truth in this.
The H-D archives only go back to 1963(they say) but i think that the older archives are just on paper and so it would be verry timeconsuming to give a idiot in Holland a answer to a question abouth a bike there not gonna make money on anymore.
A few months later i got contacted by a American who said he heard that i had my Wlj for sale and that he was interested.
on my question how he got his info and my mailadress there was a lot of BS so that makes you wonder???
Greetz,
