Please explain!!
The R-Dubb triple clamps she's using to fit the WP 50mm forks uses a KTM stem which is (was) aluminum.

sorry, this was kind of a discussion that has dragged over from the Unholy Union 2 thread,
http://advrider.com/forums/showthrea...676340&page=56
it started back when some of us were starting to have problems and questions relating to bearing preload.. somewhere around page 34 I think.
Jenna has just led the way as far as damage is concerned

the stock KTM stem we have used in the custom triples we had made is aluminium and is internally threaded.

The stock blind nut that threads into this stem is also aluminium- the new blind nut we got with the new stem only had around 8mm of thread on it, the older style had around 20mm of thread. There might be other variations? The stem itself has 20mm of usable thread.

We have had the stem turned down a little to accept the stock BMW bearings- the bmw bearings have a steeper contact angle (and are a little 'heavier') than the stock KTM bearings.
This blind nut sits on top of the triple and applies the torque and then there is a pinch bolt in the triple to lock the stem... no nut and locknut under and over the triple like BMW, just this blind nut and a pinch bolt.
From left to right, old long thread alu blind nut, new short thread alu blind nut, a long thread steel blind I made, and the swing arm bolt I made it from (conveniently the same gauge thread with just over 20mm usable),


That is what the aluminium to aluminium thread is referring to. The isssue is what figure to torque to- especially relevent as rather than setting by fallaway we can now easily do it with a torque wrench...
Hope that makes sense.
I think I'm annoying everyone with this topic


BTW, where Snowbum quotes 2.5 Ft Lb as being the torque required to continue turning the bars once they are already turning, after a little research I have read of other bikes with tapered roller bearings listing figures as high as 4.5 Ft Lb torque to do the same thing. That is torque to turn the bars and that is only a few foot pound less that the torque the KTM manual wants put on the top nut and their bearings...

Talked to terry about the stem. For now he'll just turn down my new ktm stem and drew up the steel stem. I need to get the bike on the road by Wednesday morn. Got a 100 mile commute and the car will be in the shop. Busy busy.

Any thought to making the new stem on that works like a BMW stem, meaning the stem has external threads and you adjust play with a nut?

I call KISS on that one. I took the DR stem with me that has a similar adjustment. And I just couldn't communicate that concept to terry. This was all done via phone/text as he is 2 hours from me. I leave stuff in a truck with a note. But I did think a bout it. Just don't feel much like being a pioneer right now. TAG.....you're it Gage.

Bummer. At least you know how to fix it. Gotta get it done in time for the Roaming Rally right? If that's the worst damage, to you and the bike, from that crash I'd say you got through it pretty well.

I should've had my bike to the tuner today but I'm working all week I told the GC that I'm NOT working next week no matter how much money he offers me. Let me know if you've got any shakedown runs planned before the rally. This rebuild has gone on too too too damn long and I'm ready to just ride the damn thing.

Will do! Hopefully I'll be back on 2 wheels Tuesday. I'll tear it apart again when Terry finishes my steel stem.

Well, since I've got some room to work......


I decided to clean house, and situate my electrical up front.

So, almost got it back together. I'd be riding around right now if I didn't have to go to work. Drove out to pick up the stem this morn, had to retap and press it back in the bottom clamp.

New on right.

Decided to try my LEDs someplace else.

New bars and risers since I bent the G/S bars when I crashed.

Went 20ft/lb on the top clamp, and 15 on the bottom. Didn't get a chance to put the torque wrench on the giant freakin' stem bolt as it's a 28mm and I don't have one. I'll pick one up. Went with a 50mm long bolt. I'll go and hit some speed bumps and check torque then.
