Ohlins Shock on First Gen. SV

[chris_chops]

I went home for lunch and measured the shock from eye to eye and its 13 and 5/8 of an inch long.

The spring I have on it now reads

01093 31/95 L164<-- Ohlins said this spring is for my weight.

I also acquired another spring for it that reads

1093 44/95 L164 <- I was told this spring is for a heavier rider.

I have no idea what these #'s mean, I'm going to call Ohlins and find out.

01093 31/95

01093-  this translates to a 150mm spring
31/95-   31 is arbitrary ohlins# but the 95= 95 N/mm
              which is a 542lb spring
L164 is meaningless

On the 44/95, are you sure it is not a 44/120? which is a 120N/mm spring or 685lbs.

You can actually call us instead as Ohlins USA prefers that we handle calls in or Service area.  But it is up to you.

Matt...ACC?  Don't know.  At this point, no.  Something might change, but I don't know.  Might be there for a track day program, but no racing there for me, I do know that.  Planning to do more AMA racing with my cancer program.

Dave,
When is your first school?  I would like to do it.  I've got some fork internals for the gsxr750 that I can't wait to test.

TYPO!

Yea, 44/120 is the spring I have off the shock

31/95 is the spring I have on the shock, supposably for my weight.

Good question...might be on Monday May 8th with CCS...but that wouldn't be a school for you, really.

May 26th is really the one.  Limited to eight riders and me.  Might have something else going on too, but I don't have any proper information right now.

Grasshopper...So, it seems as though that your shock length is "in the ballpark", but it still seems to suck.

What kind of rear sag did you have on the back?  How about the front?  What spring is in the front?  What kind of times are you running at Blackhawk?

Yes he is in the ballpark and his bike should be working just fine, he has the right spring too. I say he thinks it sucks for some reason other that it really is too low. Now what we need to know is why he thinks his ride height is too low when in fact it is not. What does he think his bike is doing because of the too low rear? He hasnt said yet. ??? I went back and read all his post and all he said was his rear was too low. How about it grasshopper what is your bike doing to make you think the ass end is too low?? ;D

[badmonkey]

set it at 13 7/8 if the shock is long enough to get away with it.

[Super Dave]

Grasshopper is actually reacting to the feedback that his bike is trying to tell him.

He says it's low because he's dragging and that's how it feels to him.

Really, that's good that he's trying to articulate it.  Often some riders just do stuff and wad, brake pieces, get hurt, etc.

Grasshopper...

Ok, so, I can see things in your pictures from Jack.  Yeah, the attitude of the bike is biased.

Give me some answers here.  Given what I see, I'd think that at Blackhawk:

• Your bike doesn't slow down the greatest.  You hammer the brakes but people go by you.
• The Kink has to be awful with the bike feeling like it wants to run off in the grass.
• Getting the bike to follow a line going into a corner is hard.
• Turn two might not be too bad
• Turn four after the bus stop has you runing wide all through the corner and it blows your drive to five
• Five, when you can get it to turn correctly, is a lot of fun

Really, you could use a 17" shock and it wouldn't make the bike right if other things are wrong.

[grasshopper]

Holy Crap! I can't believe you guys are giving this much feed back.

OK, I'm going to be honest with you guys about everything that has happened to me with this suspension issue.

I have RC51 bodywork that I mounted myself. I think it needs to be mounted a little higher on the bike for one. I'm going to take care of that issue.

Earlier in the season I was using a 99 Gixxer 750 shock and had the RC51 body work on there and never had an issue with ground clearence.

Then I put the Ohlins shock on there and started to have ground clearance problems.

Let me go back here for a second to the front suspension.

I have Race Tech .75 springs with Race Tech Emulators tweaked (according to Race Tech) to my weight (I'm pretty sure I have them turned in 2 3/4 turns) and I'm running 20 Weight Oil. I drilled the holes in the emulsion tubes according to race tech. I don't have preload adjusters for the front so If I change my preload at all I cut spacers out of PVC to give more or less preload. I have about 25mm (a little on the stiff side) of sag on the front end rite now with all my gear on. Forks are raised above triples 10mm.

That raps up the front.  DEEP BREATH!

After we mounted the Ohlins shock we set the sag to 30mm in the rear and had the compression 12 clicks out and the rebound 13 clicks out. So roughly in the middle.

The shock fealt good and my lap times went up. I was able to run consistant 22's and clicked off a few 20's and 21's. But the bodywork was dragging all over the place. So then we started messing with the ride height and I raised the body work up a little bit.

MAY BE I WAS JUST RIDING AROUND MY PROBLEMS! I'm not sure, I'm still learning. MAY BE I JUST GOT MORE BOLD!

But I was able to pull off a few Podium Finishes at Gingerman. Probably because of the low turnout of riders.

After that race day I had a few large holes in my lower fairing so I mounted a belly pan on the bike for the BHF date in September. I wore holes in that thing to. I tried messing with the ride height more and I still couldn't get enough out of it.

HERE IS THE SCARY PART, You guys ready for this?  >:(

Last week I took the Ohlins shock off the race bike and found that the spring was Loose in between the preload adjust Jam nut and the bottom of the shock. I think that was my whole ride height issue. STUPID ME EH?

Last night Matt and I at Superbike Italia mounted the stiffer spring on the shock and took some measurements while drinking a six pack, and as of now I'm starting all over. I'm going to record any adjustments I make and go from there.

So, I know the issue was that the spring was loose in the shock and the other issue is my bodywork is a little too low on the bike.

I learned a lesson here though. I need to be more careful with my adjustments and take care to realize that everything is tight, Included the jam nut on the shock.

But, I'm just a rookie!  ;D

So what is the sag now?

[grasshopper]

So what is the sag now?

Due to the fact that my garage is not heated all of the time and I am out of Kerosene, the task of installing the shock did now happen yet, i'll post up and let you know when I get it done.  ;D

Right on, I figured you hadn't done it yet. ;)

Matt.. stay away from this Nick kid.. he's bad news.  ;)
