Hello,

My bike is a Softail, frame from '98 and engine from '87. As bike is new to me, and I saw some leaking, I want to change all internals to front fork, bushings & seals.
But I'm not very sure if the fork is the oem one, or is an aftermarket one.
1. What fork it is? I found some similar forks by googling, but they do not have those "bumps", highlated with blue line, in my pictures.
2. What qty of oil should I add, as in the manuals, the qty is different based on different bike models?
3. Is there a dimension from top of fork tube to the top of oil? I did not find such dimension into manuals.

Thank you in advance
Marcel

 

Some looks original. Trees are. Look at the side of the sliders facing the wheel. Showa should be cast in if oem Flats would have been for reflectors.

 

Looks like you have the lower legs from the 1987 motor!!! Yes they look factory, just form an older model. Look at 80's Softails and you will see the match, good luck.

 

That set of 41mm lowers is original Style to FXWG, Trees too me thinks...But.. since lowers are Chromed...I'm betting aftermarket!!
Not that hard to open forks!! And, may be Only way to determine exactly what you have
