which oil to use with Progressive fork springs?
any thoughts on this.........
I've already decided to install the 440's on the rear of my 2007 xl50, but I have heard mixed opinions on whether the Harley fronk forks were fine to use, but best if i install the Screaming Ealge oil...
Or... do I install the progressive forks..... but which oil too use is the question??
any thoughts, greatly appreciated..
thanks,
JD

The HD SE forkoil is a heaver wieght oil and will stiffen up the front end fairly equally from mild impact to strong impact .
The Progressive fork springs also stiffen the front end but do so progressively based on the impact. If you go to the Progressive springs I recommend using standard wieght fork oil like Belray 15w. The progressive springs combimed SE fork oil makes for am almost rigid suspension.

Youhave no need to change the oil unless you are approaching 20k.

I went to the HD dealer today to get SE fork oil but Ted the parts Manager said, all I neded was the standard 15 wt oil with my new Progressive springs. So I went with the 15 wt. If cHarley agrees then I must have got the right oil...

Best of all the worlds without spending a grand to get real cartridge forks (Traxxion).

The stock fork springs are wound at two rates as opposed to progressive. I think that is why mine would "launch" when it came close to bottoming out before I installed the Progressive fork springs.
