Marty, with your 7-8 click setting, can you check your spring sag?
   I've been trying to learn about setting spring sag and your numbers will help me.

Using info I found on YouTube, {to be anywhere near what they suggest}, I have a lot more preload set than you.
I think I have about 18 clicks...

Ride safe, Ted

The rear setting of 8 is empty/no bags.  Probably a little light because I've installed tip over bars
and a few other weighty farkels since setting the sag.   I have the measurements jotted down
somewhere.  I'll give a looksie.

"By the book", your sag is set optimally set at mid travel of the suspension.  Weight of the
Rider with gear, bike, and farkrls will all play into it.  Maybe I'm more svelte??  ;D

on my C14 shocked C10 I have found about 10 clicks when one up (220 lb plus bags with minimal stuff carried) works well.  when the wife is on fully cranked to the top seems fine for the most part.  ride height doesn't seem to alter regardless of # clicks.

I have the stock C10 bone in place so it does ride high.  this thread has given me confidence to go for the 1.5" bone replacement though.  winter task.

;D

You could be right about the svelte...  (Actually, your probably right)

The difference in our posts is our % target; 
 I'm trying to learn how to set spring sag according to what I've seen on YouTube.
   They say to set the sag at {I think} about 30% (1/3)..
     Admittedly, that will make the ride rougher that what your using (1/2)..
       But it is supposed to make the handling better.
          Maybe the more knowledgeable in the club can explain??

NOTE: (from my failing memory) 30% is what they recommended, and I "thimk" I was only able to get about 40% as the springs were too soft.   Will try to find my notes.

PB: The adjuster should click. The little clicker/detent may be gummed up.

Ride safe, Ted

UPDATE: Didn't find my notes, but...  I did a little research.
              Here is a basic video of how to set sag.
                    It sez to set it at 1/3 to 1/4 of the suspension travel. With 1/4 being more for race...
                     NOTE: They are talking more about sport bikes and race bikes in most of the video's I reviewed.
                                 For street, other video's recommend the softer (1/3) and that is what I tried to do...

Again: I am not very knowledgeable on this. Not saying I have it right. Trying to learn.

Again: I am not very knowledgeable on this. Not saying I have it right. Trying to learn.

I'm far from a track guy, and sag is prefferential to the rider for the most part.  I do like the ride
more forgiving on my aging bones (partially herniated disc), so I'm pretty sure I'm not set up for track.
All being said the C-14 shock and Sonics w/emulators is still much tighter than the stock mush.
I AM good to ride 12 hour days with this set up.  ;D  It's all about compromise, eh?

 Guess I'm more marathon than sprint.   :))

I guess that's my delima..
My mind sez I'm a Sprinter, {or mebbe a Marathoner},, but my body {and my wife} sez "are you crazy"...  :truce:

So, I tinker with the bikes more than I ride them..

Question about the lower bush for mounting the c14 shock. Does it need to me 30mm or 32mm long? The other post about the lower bush shows one member had a 30mm length bush, the parts fiche shows a 32mm, and Turbojoe says 32.5mm. I’m guessing 32mm but I want to be certain. Can anyone chime in on this?

From an old Fred B posting;

For the lower mount you will need a bushing that is 19mm 20mm x 30mm.


I just measured a C-10 Rocker and that sounds correct for me.
Like others, I also built mine out of a C-10 Shock Bolt.

Ride safe, Ted

Pbfoot is correct.
I just measured the OD of a C-10 shock bolt and the OD is 20 mm.

Previously I only measured the length.. which should be 30 mm.

Hmmm.... good find... What's all that's required for the conversion? Lowering link and grinding to make it fit? Or is there more? Do you know where the best source for extra parts (lowering links etc) are?
It all started on a 250...

The C-14 shock will make the bike set higher than stock.
Some folks use Lowering Links to bring the height back to stock.
 I used Norm Soucy's lowering Rocker. {See reply #1}
    I think it best as I know it works with the center stand.

To install the shocks you have to do a couple of mods the bolts sizes and bushings, plus build a mount for the adjuster.
Other than the shock itself, the Biggest cost is the Lowering Rocker.

I'm not going into all of it right now, as it has all been discussed recently.
Here is one of them.   http://forum.cog-online.org/tiressuspension-c10/yet-another-suspension-rebuild/
There is lots of info to type again... {Hard to do with my 1 finger typing style}..
Do a quick search for suspension discussions, and you can find the info, or just go to he C-14 Suspension section and dig thru there.

After a little research come on back and we can answer your questions..

Ride safe, Ted

Update: More than you all might want to know.

Got my stretched by welding links back from welder. They were made from four links welded after being cut diagonally to make an extra length pair. This to keep C10 stock ride height with the C14 shock.

My excitement was short lived on inspection however. I had built a jig to ensure length and square of links during weld process. As these units use needle bearings this was critical. The welder elected to do it differently without jig. Unfavorable result with both out of square in multiple planes, sadly. Was going to toss them and start over with new welder if I could find one for a small order like this.

Then I remembered my jig was right on! Bolted both links in and cranked down on all adjustment to force links into spec. That would do. Wow! But how?

Removed links adjusted jig with washers to take all out of wack dimensions at 1-2 degree past spec. Then cranked down on jig again with reassembly. So far so good.

After research on the net for malleable point of aluminum decided 500-650 degrees in heat was needed. Had only 500 in kitchen oven. But no rosebud torch for next plus 150 degrees. Figured I would try the oven for four hours anyway. My wife came home at 1hr point. So that ended the oven use. She did not want to heat the kitchen as she had plans there for evening. Oh well I tried, he he!

But low and behold, miracle of miracles, next morning after slow cool down and spring back on release from jig all was in spec. Perfectly too! Lucky me!

Now to find time to pull old shock and try new C14 shock install. Am still playing with front fork tuning yet. Where do winter weekends go?!

If you have a self cleaning oven,, it goes to a higher temperature in the clean cycle.

Yeah but how hot does self clean get? Could not find that out in ovens manual anywhere. Past 650 degrees might be counter productive to mission at hand. Fortunately 500 worked.

We recently had our oven worked on.
The tech told me the temperature it reached, but unfortunately I do not recall what it was.
The main thing I recall is; it was greater than the set temp. {to burn off/remove food residue.. }

As you have the problem solved, not worth doing a test.

Anxious to hear how you like the new shock set up..

Got a break in cold weather and got my c14 shock on my 87 c10. Modified lengthened stock links fit perfectly. The ride improvement is phenomenal at rear. In Louisiana had to use 3rd click from softest to get comfort. Roads beds are terrible here. Side and center stands work as should be with no mods. So much easier to get bike on center stand due to rear tire being lowerer now. I love this conversion! Now to get fork oil squared away next!

It's a great upgrade.  Glad it all went together well.
I was never a fan of 'pumping up' the rear shock.

Enjoy the ride!
