2v SBK build thread

[junior varsity]

i do not know on either of those whether the height of the swingarm pivot relative to the rear motor mount is same as monster or like SBK.

[junior varsity]

if you get a MTS1200 motor, you'll have "998" power with a really nice maintenance schedule


not 2v, i know

[Christian]

Someone else can confirm, but I'm pretty sure all 1000DS motors are the same.

[TAftonomos]

Don't care about the height, curious about the width of the case for swingarm fitment...

[junior varsity]

Wouldn't a change in the height between the two affect geometry?

[Christian]

It would, yeah. It would be easier to make the cases narrow than to relocate the hole.

I have a 1000DS Multistrada in my garage and 996 cases on my floor. I can take a look and see the width of the MTS motor. Not sure how well I'll be able to see the height. I supposed I could measure relative to the engine mount points.

[junior varsity]

just to the top rear motor mount, front and rear motor mount distance is identical on all

the swingarm pivot hole is drilled in an elliptical region. one is higher than the other, i forget which is which, but i remember discovering it with the 900 engine+cases and the 996 cases i have.

[Raux]

the position of the hole on the rear elliptical changes the rear suspension geometry by changing the angle of the swingarm.

[TAftonomos]

Generally speaking, raising the pivot point of the arm will increase the anti-squat properties.

That being said, I can always come back and change the pivot location by machining the cases. 

I'm much more curious:

- does the 08 hyper 1100ds motor have a narrow case or wide?

- Is there a difference between the multi 1100 motor and the hyper?

The pics I'm looking at of the motor seem to show a case that is narrow, without bearings in the pivot point.  I can overcome the problem of narrowing the cases if need be, but it would be great to be able to avoid that altogether

The "core" motor I've got supposedly came from a multi, and has the narrow case (04 1000ds)

[The Mad King Pepe']

What about the S2 and S4 engine cases? Are they wide (monster) or narrow (sbk)?

TAft, have you began to think about how you will route the exhaust?

Cheers and keep the good stuff coming!

[TAftonomos]

Just have to clear up with the seller what the width of the case is, and then it will be headed my way.

I was told it is 138.7mm, which if I recall is the required measurement for the SBK swingarm.  The confusing part is I was told there are bearings in the case.....but according to the parts diagram here the bearings are in the swingarm.

Bearings in arm = SBK width if I'm not mistaken.  I just want to make sure I end up with something usable....the hyper is so weird in a bunch of normally common measurements.

[Christian]

You're correct about bearings in swingarm being SBK setup. I'd have to look at my MTS and/or S4RS to see if the bearings are in the swingarm or cases on those ones, though.

I think the S4RS is a narrow case motor though, no?

[TAftonomos]

You would think....but no.

S4R testa motor is a wide case, nearly 7" wide (rough with a tape at an angle).  The DS1000 motor I've got here that came from a multi is approx 5.5".  The ST4s (if anyone cares) is wide case...cause I stuck a S2r arm on one to see....

[Christian]

That's very interesting.

[Raux]

take a look at the parts guide for the HM and see if you can tell from there?
