So, the stock shocks are likely an emulsion shock, as oil doesn't compress well by itself.

Inevitably the oil in a shock, of any sort, or fork will settle out to the lowest point. We put in neat oil to our forks when changing it, which is the same for any shock. If we were to take a ride round the block and drain the 'new' oil out it would already be partially emulsified, having gone in as neat clean clear oil.

In all the years I have been around racing, which doesn't make me automatically right LOL , I have never heard of any NON gas pressurized damper referred to as an emulsion style damper. Call 'em what you want guys!

Lift your bike up, so the front wheel is off the ground. Drain your damper forks of oil, then refill and replace the caps. They are now sealed, air tight, at atmospheric pressure. Put the bike back down on the ground, so it's weight is on both wheels, your forks are now under mild pressure. Sit on it and they are under a little more pressure. If they are Harley air forks top them up, they are now at up to 50psi. The air and oil are still separate, as they were when first filled. Ride down the road, they are now emulsified. 'Twas ever thus, since telescopic forks and dampers were invented. The expression 'emulsified' is modern, to distinguish between them and the original separated style, which have a diaphragm between the oil and gas. It's a simple as that!

Is there a link to Pro Action shocks that has specifications for Harleys such as length and travel? I went to the web site and found nothing but generic info. Granted that there good guys and will build what you want, but it would be nice to have some base line info ahead of time, prior to calling them.

They will tell you all you need to know and more.
The web site has the lengths, 11 12 and 13.

At first I didn't really like these shocks, thought they where to stiff, but after thousands of miles they have broke in or I got used to them or both. They did fade bad on a 16 hour day about 800 miles , 350 mile days are fine. Don't ever want to do the twin cities to mid Michigan in one day again. Going to try the thicker oil in the forks come spring.

Ok - I figured out my confusion and lack of info problem. Go to http://street.pro-action.com/ not just http://pro-action.com/ No useful Harley info on the latter and no apparent link to street info.
