Tubeless Conversion?

I checked the schematics, and there seems to be some sort of strip covering the spoke nipples(it doesn't have a proper name in the picture). Is this a similar setup as with the 690 rims mentioned earlier? If so, do I have to take some special precautions when removing and installing a tyre?

There seems to be some confusion here. You just have a normal rim strip covering the nipples so the spokes don't poke the tube. Whether you have tubeless Scorpions is completely irrelevant, you still need to use a tube unless you seal the rim using the methods described in this thread.

The special sealing strip is only used on the 690 SM, together with a special rim.

Thanks for clearing this up. I just got around to unpacking a set of new tires which I got and was horrified to discover that they sent me a tube type front. Now it doesn't matter.

Last update (I hope): They're done! They're freaking done! Both wheels have had 41 psi in 'em for a week now, and that's good enough for me. WooooHoooo!!!!!

just out of curiosity, what kind of tires are you running. my 908's seem to lose air after a couple of weeks. i think its the tires not my wheels. btw i fill them with nitrogen.

After reading the whole thread, I am still unclear as to the 21" front on a 990 Adventure. Is there concern with sealing the inner spoke area and going tubeless? Can someone explain the tire "rollover" issue? The "safety strip"?

I have had very good luck with the Tubliss system on my dirt bikes. In addition to sealing the spoke area, the Tubliss (inflated to 120 psi) acts as a continuous rim lock, keeping the tire in place even when the main air chamber is down to zero.

So, has anyone tried or considered the Tubliss setup for a 21" front on a big adventure bike? I realize that the Tubliss is not DOT certified but I am speculating that this is more administrative/certification cost prohibitive than real world.

Thanks for all the great discussion!!

As I understand tubeliss not getting dot certified is more then admin. Not sure I would ride the 990 at 120mph with tubliss in place. Awesome answer for motox and trail riding on smaller bikes though!

With regards to sealing the 990 rims. I have been told The front 21 inch does not have the tire to rim locking like the rear. It doesn't have the inner lip to hold the tire in place? It doesn't really need to be tubeless either because most punctures happen on the rear wheel and the front doesn't create the heat that the rear does, that can cause problems with tubes.

Seal the rear! You'll dig it!!
Cheers!

Yeah, you've got it: the rear has a safety bead, which helps keep the tire on the rim in case of deflation, the front doesn't. Of course, if a tube suddenly deflates, it doesn't do much to hold the tire on the rim either. Tubliss seems like it should do some good holding the tire on the rim, as long as their setup is made for the width of the ADV front rim.

And yeah, try the sealed rear wheel- it really is a great feeling to put in a tire plug, air up, and ride off, rather than replacing a tube.

Just sent them a note,,, they don't list a unit for a rim as wide as the 950... But it cant hurt to ask...

Yes, I have been running Tubliss on the front of my 950 with no issues at all. Woody's superlaced Excel rim and a TKC80.

Bashed it through the rocks, high speed on the slab ... no issues other than the tire has a slow leak ... I probably need to deflate and re-seat the bead.

CJRacer has also been running Tubliss on his 950, which is what sold me.

My rear is a Woody's superlaced Excel rim, tubeless.
