Drove all around town looking for some Threebond, or anything resembling Yamabond (Closest Yamaha dealer is 40mins away, and no local shops have anything), and I came up with this stuff to put the case halves together on my YZ250.

Anyone used this before? Or anyone have an experience with it?

This is a clay based gasket sealent. It does dry out and turn brittle with age/heat. But it takes years.
I would try for something better. The Right Stuff might be better, sold at automotive parts stores.

I am interestd if anyone else has experience too.

Don't do it. A good seal is important especially in the crank case. Order the yamaha sealant from bikebandit.com.. There pretty quick on shipping. Worth the wait.

I use more or less same material for years without any problem:

It is non-hardening one (and gasoline resists), but it is working perfect!:excuseme:

If you going to use something from Permatex, and not the recommended Three-Bond, or Yamabond..
Use this
MotoSeal® 1 Ultimate Gasket Maker Grey
This is the product Permatex recommends for case sealing. I sent emails back and forth several times.. and this is the recommendations I got,,, But good luck I finding it on the shelf anyplace. I've never seen it.

Well I put the cases together yesterday with it, and from the sounds of it, it will work?

Can anyone say for sure it won't seal? If so I'll bite the bullet and try to get the right stuff in the next couple days.

Is it the recommended product from the folks that make it? NO
Is it the recommended product from folks that have other choices? NO
Will it work? Who knows,, there are thousands of sealing products out there.. you chose one that is not recommended.. the TDS seems to show it's not a terrible choice.. But it's a gamble, considering it not a known working product from those that build engines, and the company that makes it, does not recommended it for the application.

Hello
hmm don't you think that the companies who produce some of that stuff don't have motives like sales behind that kinda recommendation?

If you have a Toyota dealer near by you can get FIPG get 2 tubes one is black and will seal dry it's good for when you have to pull the water pump back of and the flimsy card board rips but the second is the one for the cases and it's the orange FIPG it's main use is for trans fluid or case halves on diffs either way it's the same sealant as yamabond it doesn't dry solid and it works, don't forget Yamaha and Toyota have been in bed together for years it's the same stuff the tube the factory uses is even grey

FIPG -- Form In Place Gasket

Get Yamabond 6B. The Permatex stuff yields to gasoline/premix and creates an air leak. Funk dat1

I hear the Toyota stuff is good too. But I have personal experience with the grey Motoseal failing multiple times on my TZ250, and Yamabond 6B solved that problem.

you want the original yamabond that they use, you can buy it at any Ducati dealer as ducatibond. Or any Subaru dealer as fujibond. The real stuff is the best.

Anyone tried Loctite 518? You can be sloppy with the application and where it's not pressed together it'll stay liquid to be removed at the next oil change.
