Default DOS 27mm Installation Instructions

Does anyone have a soft copy of the installation instructions for Department Of Suspension 27mm triple clamps to suit a 996 with Showa forks.

Cheers

Tried emailing department of suspension to get a copy of the installation instructions for his 27mm triple clamps that I purchased used on ebay. Let me say that this guy is a major tool. I didnt need him to provide custom suspension settings to suit me specifically just the basic instructions on how to install the damn things. His reply to my email request was "You are not my customer.Therefore you don't get my support" what a charming guy. So to anyone who wishes to purchase used dos triple clamps don't expect any after sales support as he charges by the second for his attention. I appreciate the guy wants to protect the knowledge his built up but not to support his product at the basic level is disgraceful. I should have gone to Ducshop instead, surely their customer service couldn't be any worse.

There I feel better now

Go back and search for the DOS on this forum. Some interesting reading.

I sent you a PM

I understand people wanting to be compensated for their effort, but sometimes people can be a little abrupt.

The good news is, that there is no monopoly on the information. If you are looking for a good starting point you can search the archives for Section8 information, or just ask Ducshop. Several members here still ride the older superbikes, and may chime in as well. Hell Travis (DemonTech) probably has an old Ducati setup spreadsheet somewhere.

BEN710 it's what I don't know that I need, I understand that step by step instructions are provided with the triple clamps. I can install the clamps easily but it's the small "please take note" and "ensure this" things that maybe overlooked. It's these step by step instructions as well as a basic setup starting point which would be nice to have when undertaking such a task. I have searched the forum and have a general idea of the settings it's just more confidence inspiring when you have the info straight from the horses mouth as it were. It's a shame that some people put their pocket a long way ahead customer satisfaction, it makes money for them initially but becomes their downfall in the long run.

Well if I was you, I´d follow the instructions in the service manual. If you tell me which model and model year bike you have, I will see if I have the workshop manual and email the pages you need to you.

But then, it´s pretty straight forward. All you need to do is uninstall the front wheel, calipers and take out the fork legs. Then loosen the upper triple clamp and remove the headstock bearing nut (the soft aluminum thing with the holes in it in the middle of the upper clamp). You can pull out the forks along with the lower triple clamp to the bottom then. Hook up the new triples, lower first with the headstock nut installed so it won´t fall out. Install the fork legs, then upper triple, make sure they´re aligned properly. Then take the chain spanner tool and move the eccentric around. Make sure to loosen the lock nut before you try to turn it Through the lock nut´s hole, you can see when the eccentric is in the proper position. Tighten it up again and after all the installation of fork legs, handle bars, do not forget to tighten the headstock bearing properly. I think I tried 60nm, which was a bit on the loose side. You´re going to get a little clicking noise and feel when braking. Then it´s too loose

Hope that helps. It´s pretty mich straight forward. Oh and I am running a 96 links chain, 2 more than stock with 14-38 gearing. That allows the rear eccentric to be at a 4 o´clock position. You´d have some room for adjustment and you´ll be running a longer wheelbase, which is quite good.

Please report back after you have installed them. I did 2 track days and 1 endurance race with the triples and think they´re quite good. Not that it would make that huuuuuge difference that everyone kept bragging about, but it certainly helps a little bit. I could write more about the experience, but don´t want to hijack your thread

Thanks Ben710, your assistance is much appreciated, I should have most of it worked out but am not 100% sure with the rear ride height. Many have stated a figure around 235-253mm (DOS state 253mm). My question is, is this figure measured from the top of the sprocket carrier nut or from the centre of the axle? I too am running 14T and 38T sprockets with a 96 link chain. I will be setting the forks with just the red tops showing as a starting point.

How does the top triple clamp look like? If it is a straight line design, I have set the forks at 2 rings showing on the inside. Look here:

http://www.speedzilla.com/forums/duc...perbike-4.html

Last quarter of the page.

Rear ride height - do you have thge Ducati tool? If so, center of the axle to top of the ride height tool 253 probably is too much to start off. Iirc my tuner recommended 246 and 3mm are going to make a difference. I will look it up for you though, as I am not 100% sure. This figure comes from the top of my head.

You can try 226mm from the top of the rear sprocket carrier nut to the top of the ride height tool. I am 100% sure about that one. See if that equals the center of the nut recommendation.

That should work for a start. Remember: suspension is a very personal thing (no not like a girl´s first monthlies or such). I tried the DOS/S8SBK settings 2 years ago and disliked them. If I were you I´d start with 2 lines showing at the front fork and the 226mm recommendation in the rear and go from there. More rear ride height is going to make it quicker on turn in and less stable. Less ride height will give you more rear traction but less turn in. At least that´s what I have learned from my own experience.

Please keep in mind, that I am just a user and no suspension tuner by trade. I am still in the long process of learning and trying out this new setup. I hope it can work as a starting point for you, to get you into the ballpark.

If you have any further questions, just post them up.

253mm rear ride height is reference for the DoS ride height tool...vertically, from the top edge of the tool to the center of the axle... I'll try to snap a pic for you

One note: the chassis tools can vary in design, i.e. Ducati, DoS, Motowheels may all be slightly different from each other. 253mm on a Ducati tool, may be 10+mm different from the DoS tool.

That´s why I was asking which one he had. I think for perfect generel reference, we should all refer to the original tool. But then, yeah... this makes it quite different hey.

I really dislike the "eye-to-eye" measurement at the ride height adjuster.

Thanks guys for the info, I have what I suspect is the ducati ride height tool (bought it many years ago and never had any brand name on it) so from what your saying I need to remove approx 10mm from MW and DOS ride height settings? Ben710 no mine are different not as many hole cutouts and more angled at the top (did DOS change his design?). Does this change your 2 lines showing suggestion? sorry for the lag in response guys Im in Australia and the time zone means I either respond early morning or late evening to catch you. Ben710 nice pics of you bike, Mine is yellow with carbon bits too. I have a 1036cc with the same 748R shower injectors machined out to 60mm made 145HP on a Dynojet. sorry to go offtopic but couldnt help myself.

I couldnt tell you the correct baseline setting for the Ducati tool is, as I have the DoS tool. Mark Sutton from Ducshop in the U.S. has a lot of good setup info...IIRC, he's also on this forum, so you may want to shoot him a PM. He's the one that informed me of the discrepancies between the different tools.

If phoning GMV 121 fails, let us know so we could both measure the eye to eye distance at the ride height adjuster and then compare how it comes out at the rear using the ride height tool.

Can you show us a pic of your top triple clamp?

Nice to have a 1036cc engine, 145 rwhp sounds wicked! Do you track it or is it a streetbike as well?

60mm TBs... meeeowww!

I was going to compare my bikes geometry with what has been posted here just for my own curiousity. My triples are 27mm offset and the top is a flat design. But I have 999 forks, I can't recall if they are longer or shorter than stock 748 forks. Can anyone recall if they are the same length?

Also the bike is Yellow with some carbon bits, naturally! But it makes do with 50mm trumpets.

It's a bit more pedestrian than Ben710's bike, but I love it just the same.

GMV121 nice to hear from you, who is Computrack and where are they situated? Ben710 It is street registered, but have taken it to the track. It keeps the jap 1000cc bikes honest down the straights.
