these two last replies show us the answer !THANKS Rudy ! THANKS Neil !!!!!
TWO TYPES of offset forks !!!!!
one early ( i think the so-called "rearward" by Pa )
and one late ( with straight legs )
this problem is as tough to resolve as the offset forks has had a very-very-SHORT life !( two years only ? am-i exact ? )
ans i THINK :
as this springfork WAS JUST kinda "quick-made ALTERNATIVE SOLUTION" to the HYDRA fork ( not completed yet at the factory during these years )
Harley DID NOT talked and explained A LOT about it ! ( thinking "no time to loose with this crap : the HYDRA fork is COMING SOON !!!! ")
NOBODY SEEN THE DIFFERENCE !!!!!!
the early offset fork :
they built it ON THE PAPER ( plans and mathematical trail and rake calculations )
the late offset fork :
they built it ( modifyed it ) thru the BAD CUSTOMER'S FEEDBACK !!!!THIS IS WHAT I THINK !!!!!
coz there's today on the earth NOTHING to PROOVE IT ( not even Unka Bruce , i guess .... )
