Do yourself a favor. Set you bike up with Ricor Intiminators and IAS shocks. You will save yourself a lot of time.

You do realize there are several ways to get the suspension properly set up. Money is the key variable. If Ricor and IAS shocks were the only correct solution, everyone one else would go out of business I should think.

I think by the time I have gone through everything, I may end up where you are trying to send me, but I may not...

Give me about a month or so to try a few things. One thing for sure, I appreciate one of the sites knowledgeable members helping me..

Certainly, see all the springs in my avatar, that is all Sportster stuff. Dirt bike stuff from over the years would be even more. Let's just say, I quit all suspension testing once I got the Ricor set up perfected.

Not everyone needs, or can afford, high end shocks. You can, and do. You just don't know it yet. Do this, put your shocks back on and make installing Ricor Intiminators your first mod. Then report back. Ricor Intiminators are by far the most popular and effective fork mod.

The history of Ricor Intiminators is well documented on this forum. I did a lot of test riding for them setting up their shocks, but I have no financial connection other than getting Intiminators and IAS shocks, and Vibranators for free. That's my official disclaimer.

Back to basics. The lower triple clamp may be limiting total travel. When you take the forks apart, check total fork travel with spring out.

What rebound damping are your referring to? Regular shocks or Ricor IAS shocks? I don't know the actual number in either case, I don't have any way to measure it. The dampening mechanisms are different, and detailed in the link to Ricor Intiminators in "7 Pages". Too much to repeat until I have more time.

I copied this from "7 Pages of Suspension." If I remember correctly, start reading after post 53 where the animation of the Intiminators are. Before that, everything was speculation.


Quote:
Post 53 has an animation of how the Intiminator works. However, for our bikes, the oil ports are above the moving yellow collar. If you look at the tube in the very center of the animation, near the bottom where the collar reverses direction, you can see the ports open and close as the collar moves up and down

My test rides are on posts 136, 173, 185, 295.

Post 289 has pictures of fork damper rods.
Post 298 CBNightster explains how to change damper rods. He used a Low damper rod in his Nightster to get some extra travel.
Post 337 is a picture of my fork cap installation clamp.

Trying to compare Intiminators to Emulators is like trying to compare a Corvette to a Chevette.
The main Ricor Intiminator thread: Front forks...what can we do ? I have the answer

Anyway, I think it is great for your to document Harley's set up. Aren't you wondering WTF were they thinking yet?

If you find replacement springs and parts to rebuild 1200S shocks, the value of those shocks will go up dramatically.

Well, FWIW that's what 37#.

That's not JUST the windshield and bags (though they contribute).

That also includes a the passenger peg mounts and pegs (which are not small, especially the mounting brackets).

And it includes other small things that I guess add up .... a 2-up touring seat instead of solo, larger/heavier mini floor-boards instead of the small standard pegs etc. Hell, I wonder if the chromed motor is actually heavier than the bare/coated aluminum... then again the 883 had more aluminum in the jugs.

<shrugs>

I guess 37# doesn't actually sound like that much to me anyway...

I generally say 30 lbs is the minimum extra weight a rubber mount can carry before the rider starts to notice the difference the extra weight causes. If the shock spring rate is on the normal to heavy side, and the rider can dial in more preload, and has enough travel, it is not a problem. However, if the spring rate is already too low with preload maxed out and only minimal travel to start with, extra weight only makes things worse.

Some running weights from the 2014 owners manual:
1200C: 584 lbs
1200CA: 584 lbs
1200CB: 584 lbs
1200T: 599 lbs
1200X: 562 lbs
1200V: 562 lbs
883L: 562 lbs
883R: 584 lbs
883N: 562 lbs

We get the 1200C and T models, the others are foreign markets. So, that's a 15lb difference to the C model. And yes, it is a 37lb difference to the 883L. Don't make me too heavy before I make any changes.

Snow day today, so I get a few hours to fix a few things in my big post last Sunday. I tried to make a few things more clear on what I'm doing. There will be a pop quiz later in the month.

I can see I'm probably going with the 2003 XL1200S shock with the 1986 VF700C springs as they look to have the right spring rate for my needs. See the additional new posted material from last Sunday.

Here is a pic of what the shock looks like:


You can see I ditched the fancy chrome top and bottom trim pieces. I will be testing these hybrid shocks this weekend in this configuration, but i am exploring a possibility of replacing the oem chrome preload adjuster with 4 indent preload adjustments with a coil over sleeve arrangement. I have something on order and will look into this as it should be stronger and allow greater precision on setting up the rear sag.

There is lot to get done this week end to still sort out the suspension. Since there is ~5" of snow out on the ground, there will be no riding for a few weeks.

I don't think the 2013 XL1200R shock exists and that is a 1200S shock in the picture.

Be sure to double check the clearance between the ID of the coils and OD of the shock body. Some springs have an internal taper that clears when extended, but causes contact when compressed.
