If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • This forum is for placing reviews for parts, accessories, gear and service as it relates to your GS motorcycle. The key here is "GS Related". There is a bit of latitude here but we don't want to see a review on Maytag washers just because that's what you use to clean your riding jacket in.

    Keep your review as factual as possible and please refrain from personal attacks. Posted articles will be reviewed by the Editors and may be removed at their discretion.

    So let's make this a useful addition to the forum! A special pat on the back goes to Hap Call for coming up with this great idea.

DynaBeads

$18 a bike. Steeper than stick on weights, no hiding that. But idiot resistant, very convenient, and reusable if you're patient. Mine are in their 2nd set of tires.

I seem to recall reading a recommendation to drill a hole in the old (tubeless) tire before dismounting it, then rotate it down to capture the beads for reuse.

I haven't tried them myself yet.
 
The airsoft bb's will not fit through the valve stem, but on a 33x12.50x15 tire there is plenty of room if you pop one bead halfway loose. I have seen the slight rubber dust you speak of, which is why I was wondering about tubes. I don't trust the toughness of tubes very much, hopefully someone will try them and post up.
 
On Dynabeads website they say they are safe for tubes, they also have a "delivery system" for getting them in via the valve stem...

I looked into this at one stage & they are similar in cost to clamp on weight for spokes or clamp on weight (bang on clip type) for mags. More expensive than stick-ons but can be re-used as you say :)
 
Dynabeads are just rebadged grinding beads, they are heavy ceramic beads that cost a few bucks a ton. An industrial supply place should have them. You need the right size, I believe Dynabeads are 1mm in diameter, although larger beads would work as long as you can get them into the tire. BBs work but they rust, airsoft beads do too I have heard. The beads work well and they are in use in a lot of truck tires, but not so good in wide low profile tires such as a modern car uses, as they don't distribute themselves side to side properly. This is of no concern in a motorcycle tire. I put them in all of my bikes whenever I change a tire, have been doing it for years. The bikes run smoothly, tires last a lot longer, especially the fronts. (they don't do much to prevent rear tire wear from heavy throttle usage :D )

No one who has ever ridden any of my bikes has ever complained about a tire being out of balance.

That's what I did. Lost a few in the process, but not enough to worry about.
 
If you cut a large hole in the old tire with a box knife, it's easy to pour them into a pan or something.

I used them in a tube on my rear tire. No problem. You do need to be patient pouring them through the valve stem. If you go too fast, they jam up. Then you get to spend the next few minutes tapping on the stem to vibrate them through. Or, if you really went nuts, you'll want to turn the wheel so the bead pour back out into the bottle.

When I get my "dealer kit" It has a "vibration tool"

I think someone posted in tips and tricks for using a women's pleasure device to vibrate air bubbles out of a brake line... Just sayin. I used an electric toothbrush to get mine through the valve stem.
 
I've been using Dynabeads on my Hayabusa and they work great.

Of course, I never exceed the speed limit on the Busa, that would be illegal, but I do occasionally go up to exactly the upper end of the speed limit.

Plus or minus. ;)
 
I was thinking about trying dynabeads on my next tire change. When using these do I remove the old tire weight or will the beads still work with this weight still on the rim? Totally new to this process.

Any help is appreciated.

You must remove the old wheel weights when you mount a new tire. If you don't remove old weights, they can become an extra weight the beads may have to counter balance.

Think about it for just a moment. :-k

Those weights were applied to correct a particular situation.

That situation has changed (with the new tire), it's about time to change the correction, too.
