Title: tubeless tires
Post by turuncuoglu on 03/22/12 at 12:32:50

I am rider with not much experience.  I like to take things slow and only ride when there is 0 chance of rain.  

Last year I had a flat on my rear tire and needless to say I was pretty scared.

Now I am aware that the due to spokes it is not possible to put tubeless tires on the wheels.  But what is involved at changing the rims on the savage.  My local Suzuki dealer quoted over $600 for a pair of rims. I understand motorcycle rims are different then car rims but still $600 seemed little too much. Is there an online store that sell these. How do I even go about finding them.

Thanks
T

the most common thing people do here is swap out our rims for rims from an early 80's GS motorcycle (gs450, gs550, gs650).

Search for "whale" or "mag wheels" and you'll find some more information on the topic.

for "finding" rims you'd have to find out our axle diameter, rim diameter, brake rotor bolt pattern, and spacers to get the wheel/rotor aligned for the front tire. the rear tire you'd have to find something that has the same drum brake setup and the same hub for the belt. the 80's GS550L bike is the only one I'm aware of that does this.

of course, if you want to modify your bike a little further, you can swap front ends and put whatever bike's front end you like up there as long as it fits the steering stem bearings and doesn't radically change the steering geometry. for the rear, if you switch to a chain drive you have more options as well, but I've never looked into that (because I secretly hate chains for no good reason).

Not much advice I can give to a newb... a flat's a flat.  whether it's tubeless or not.  If you want to know immediately that you're loosing air, then get a tire pressure monitor.  can be had for less then $200.

so does that mean 1981 GS550 front and rear rim would fit to the bike with no modification?

Well there is a difference between slowly loosing air and suddenly having a flat.

Of course you can put tubeless tires on a rim with spokes you just have to put a tube in it.

A "tubeless" tire is designed so that, given the right "environment", it doesnt need a tube, using a tube in a tubeless tire is not found anywhere on the list of deadly sins.

I actually run with tubes in my tubeless tires on the mag wheels my XS750 has. After I got the bike I went to change the tires and they already had tubes in them. Not knowing *why* the PO had put tubes in them, i figured it best not to risk a leak due to a 34 year old rim not having a clean seat for the bead and i put the tubes back in.

People look at you kinda funny when you tell them you run tubes in your tubeless tires, but it isn't hurting anything.

You can run true tubeless on the stock wheels. I think it is American Wire Wheel that does the sealant process. The company receives your rims, mounts them in a fixture that will let them free spin and trowels on a silicon sealant. Once it dries the spoke heads are permanently sealed. Then the sealed rim gets balanced and shipped back to you.

Pretty common conversion for Harley rims.

You could also try Buchanans and see if they can lace a set of Honda CMX450C style hoops to your stock hub. The 450 Rebel had a dropped flange that the spokes laced to, a truly tubeless spec wire spoked wheel. BMW used to use the same style hoop, so somebody has them...

If you are going to do either of the above, you'll also be money ahead to have the rear hoop replaced with a 16" version. Lets you choose from hundreds of tires instead of a handful.

yah you can make 'em tubeless but get someone who knows what they are doing...
Quote from Woody's Wheel Works in Denver

"Q: Can you make my rims tubeless?
Woody sez: We will only make wheels tubeless if they have the safety bead in them, and that can be done with a broad range of custom wheels that can currently be built. We can enhance the chances of you not having to dicker with tightening your spokes and thus ruining your sealed rim by having it SUPERLACED; we are evaluating if it is feasible to re-invent the 950 wheels using the GS BMW series technology

What has worked before in most riding situations is being challenged by two new demands placed on the existing rim sealing technology.

First, the use of tire warmers by supermotard/road racers raises the rim temperatures far above 'normal' use, causing the sealant to soften and then separate from the rim due to centrifugal forces

Second, the lower tire pressures being run by the off-road enthusiasts. I think that's why KTM designed that lip as added insurance to keep the tire from slipping off at lower pressures, we have machined/changed the profile of the safety bead for those riders that demanded easier tire changing capabilities.

I can write several pages on the many factors that are involved in making rims tubeless. There are so many - the obvious like correct rim selection and IMMACULATELY prepping/cleaning the rim and nipples are easy, it's the little stuff, ie. spoke and nipple selection. ss spokes and ss nipples? Wow great!!...not so fast...if you don't use the special anti-seize lubricant provided, you can't tighten them adequately and they gall and seize on you, use it and try to go tubeless and the lubricant slowly works its way between rim and sealant compromising the seal...and on and on

In creating solutions we have to constantly balance our objectives within the parameters we can live with, and they can be as varied as how much am I willing to pay for this, will this set me up for a lawsuit in litiguous america, am I sacrificing safety for that added edge in competition... etc"

I've got a similar question on this - I'm converting my Savage to a sort of cafe/scrambler kinda thing. I want to put Shinko 705s on it, but for the life of me I can't find the 110/80/19 in the tubed variety.  
I read somewhere that for running a tubeless tire on a 'tubed' rim, the rim itself has to be a of a certain cross-section for the tubeless tire to fit, but now I can't re-find that article.
Any thoughts?

A 110/80 tire can fit on a 2.15 wide rim. There is a tire fitment chart in both the Cafe’ and New Tire threads- I am on my phone and can’t seem to attach a link.

Be careful early GS models had cast wheels ,but they weren't tubeless.

All savage rims that I've seen can mount a tubeless tire. 88-08

On another spoked rim bike I have (Honda Africa Twin), I converted the spoked rims using the Outex system to allow me to run tubeless tires.  over 11,000 miles later in one year, i have had absolutely no leaks on the now tubeless tires. Outex can only be bought on eBay.  Many people on my Africa Twin forum use Outex for their dual sport bikes with no problem.

Outex,,
Sounds like doxing someone..
Kinda pricey.
Did that make balancing more difficult?
Mounting?

I was going to use 18" alloy rims on my build, so I had Woody's Wheel Works do their tubeless conversion at the same time. Basically, they use the Outex kit which uses a kind of rim tape to seal the rim.
Not sure if the stock Savage is a 'safety' rim, which is the kind that can be converted to tubeless. It wasn't an issue with me, as I was tossing the stock stuff.
If you do the tubeless conversion on a non-safety rim, there is danger of the tire coming off with a flat.
I also did my Triumph, and made put a bunch of trouble free miles on the wheels. Pretty cheap, maybe $120 for both wheels.
If I get a flat in the middle of nowhere, I'll be able to jam in a tire plug, fill p the tire with a few CO2 cartridges, and ride away. With the tube set-up and no center stand, basically, you are stuck.

After using Outex how do you adjust the spokes, true the rims ?

Title: Re: tubeless tires
Post by Armen on 03/02/19 at 13:17:58

Batman,
The first step in the kit is to apply little Polka Dots on top of the spoke nipples. Then the two sided tape strip, then the plastic strip. The polka dots allow the spoke nipple to turn without twisting the two sided tape.
So, basically same as without the kit.

Title: Re: tubeless tires
Post by playhard67 on 03/02/19 at 18:28:32

regarding Outex.... I have not had to true the rims or adjust spokes after installing the Outex system.  However, there are additional "dots" and tape provided that if you have to adjust a spoke or more, you can redo the seal.
