What weight of fork oil should I put in my 05 Dyna super glide

 

Welcome to the forum.
Assuming you have a stock front end and no handling issues, I would say go with the stock 5 wt. oil. You can go to 10 or 15 depending on your set up and how you prefer it to ride.

 

i always recomend spectro 15w, really does well to cut down on the dive these bikes have in turns

 

I changed out my stock springs in the forks with some Progressive (standard length) and running 10W Bel-ray. The difference is night and day.

 

I rebuild my tubes with HD OEM parts only, added just at 3/4 inch preload spacers, and filled with 15W Bel-Ray...Sag is good, it rides smoother but the brake dive is still a little much for my fat ***. I am thinking intiminators next..
