Hi, to all i am having my 2004 Road King custom flhrsi forks replaced with chrome one's and i am not sure on what type of oil to use. I've been going through old threads and there seems to be various preferences on type E, type B, SE heavy and SE extra heavy. Any suggestions from Road King owners on what is the best fork oil to use?
Thanks

 

I used to use Screamin eagle hvy in my 04 flhtc,but i found at my 15-20 thou oil changes it always looked like ****.I am now trying BelRay 20 wt instead of the Harley crap.Some people prefer the 15 wt .

 

Race tech has some good fork fluid and so does amsoil.I have used them both and have had good luck with them.

 

Thanks

 

Welcome to the forum. I just recently posted this fork oil thread. Maybe it will help.

 

I can tell you only from my personal experience. Keep in mind that mine is an 09 so I am not sure how much difference there is. At first, I was going to use the SE heavy because everyone on this forum was talking it up. Then I realized that most of them had a fairing also. I ended up going with the factory recommendation "type E". I am very happy I did. Very smooth ride but that is what I like. I was just afraid the SE heavy on the Road King might be a little too much. It is easy to change if you decide one oil was a bad choice.

 

I ran the SE heavy in my old softail best change I ever made, really stiffened it up and made it able to handle rough rodes without bottoming out

 

Mix 60% racetech US-2 With 40% US-3.
