1000DS closer shim adjustment

[WetDuc]

Alright I found the sweet spot He Man was referring to.  That does work nicely to hold the closer rocker out of the way.
There is a picture of where the sweet spot is on the EMS website:

Hey WetDuc,

I'm at the same place. I had done valves on my 620 3 times and had it down. Now I'm learning the differences of the DS. The one thing you should check right now is that you don't have any broken half rings / keepers. My V intake closer was loose and my H exhaust opener was tight. I used the number on the side of the closer to order the closer I needed and the 7mm tool at the same time only to find out that the half ring on the loose closer were broken and now I'm waiting again.

I was able to get the closer off pretty easy just pushing down with a big flat head but now I'm thinking from this post it might be hard to get the closer back on. hmmmm

[WetDuc]

My half rings are not broken.  I ride almost everyday, but mostly very reserved city riding style.
Jamming the closer rocker arm to work on the closer shim assembly is really nice IMO.  Once I jammed it right the very first time, I could get it again perfectly.  Anything to make the adjustment easier so I can enjoy frosties is cool.


My closer measurement tool and LT manual came from EMS today, in only 2 days.
I really love that little tool.
Did all my measurements on my shims, most very close to, but all less than printed size.  One unprinted shim (strange).
I'm shim shopping with mic in hand tomorrow at the dealership.
Maybe I can have her back together and do my tune next week (gota travel this weekend).

So what's so special about that tool?  Made of a hard plastic??  Getting ready to do my DS1000 vavles, but I can make something like that in a snap at work...

It's the closer shim measurement tool he's talking about.

wetduc what size do u need? I have a kit with a lotof repeats that im looking to exchange

[WetDuc]

OK, sorry for the delay there.  My Excel file with all my shim data decided to crap out on me.

Just to make sure, I am calculating my new shims required by taking the difference between the optimal clearances (.005" exhaust opener, .004" intake opener, 0" closers, [inches]) and my measured clearances then subtracting or adding the difference to the actual measurement of the opener or closer shim I have, respectively.  Sound right? 

Switching to metric now [millimeters].

It seems I can shave about 0.1-0.01mm off of my existing openers to bring them into spec, so I don't think I need to buy openers.

My resulting numbers seem feasible for required new closer shims:
Hor exhaust closer 3.0302 (3.05)
Hor intake closer 3.18006 (3.20)
Vert exhuast closer 2.97178 (3.00)
Vert intake closer 3.10894 (3.15)

He Man, if you got 'em I have to leave town tomorrow so I have a bit of time to wait on shipping.  I haven't bought my shims from the dealership yet.  Just let me know.  Otherwise it only looks like I need 4 shims, so that shouldn't be more than about $50 at the dealer...I would hope...

[He Man]

ill measure em out and see what i can exchange with you. i wouldnt charge you any, unless you want to buy a speific one off me. I just want to get rid of my repeats.

[WetDuc]

I hear ya.  Just shoot me a PM and let me know.

Yeah, I know that...but to me it looks like a strip of 1/4" steel stock with a few notches/fillets in it...So I'm asking because I can make something like that in 10 mins vs. buying and waiting for it to come.

No no. The closer measurement tool is a small piece by EMS that slides into the closer shims so that you can take accurate measurements

It is worth the $12 or whatever from Desmo Times

[WetDuc]

There are two tools that make duc life so much easier:
The Closer Measurement Tool (Measure your shims!  This is a exacting, precise and accurate lathed round stock SS  piece with special notches that fit the half ring counterbore in the shim)
The Closer Depressor Tool (No more flying half rings and curse words...lock your closer rocker arm depressed!  This could be a dang toothbrush as long as it jams the back of the cam)

I love beer.

you could make a ruler with a piece of wood and pencil, but doenst mean its accurate enough to measure stuff like a shim to the .01mm

I guess I should have clarified:  I'm not planning on making the closer measuring tool - I deal with precise machinery on a daily basis and have a full grasp on why measurement items need to be precise.

What I was talking about was the closer depressor tool.  Having full access to a machine shop, it looks like something that could be fabed up in half an hour...But, pictures can be deceiving which is why I asked....if it has some fancy flat surface or special groove to hug something, then it's not worth the head ache to make it.
