Potatoho,

I posted 3 replies I recieved from Sommer KTM in Germany here:

http://www.advrider.com/forums/showt...ghlight=sommer

Note they did not see the benefits of a racing cam without high flow headers (Akrapovics or probably the KTM Ti supermoto headers). Maybe the SXC dual pipe setup would do it Just another piece of the pie that creeper stated.

I've read that too. But my sprocket is on backorder, and I gotta mess with something.

Loctite 515 better? I see the RFS bulletin recommending it over the threebond sealant.

is that stuff Thixotropic like the Permabond stuff?

Just curious about this stuff - no gasket for better "load transmission"?

Here's the bulletin I read: http://www.egetadeal.com/mx/tips/jeb...5_bulletin.jpg

Holy moley Meat....

I've heard of thixotropism applied to catsup, but not Loctite....what's the application? The groundlings need to know....

I cried too.

Thixotropic: The viscosity decreases as the shear rate increases.



there shouldn't be any shear stress in this application so that works right? it's just the thumper paint shaker that makes me wonder why this stuff doesn't liquefy and seep out?

"Permabond A136
Ready Gasket / Flange sealant
An anaerobic material designed for making ‘formed in situ’ gaskets between metal surfaces. It is capable of replacing a wide range of ‘conventional’ gaskets thereby offering potential for reduced stock holdings. By allowing surface to surface contact load transmission can be improved. As the product does not shrink, creep or relax after curing no bolt retightening is required. Its excellent chemical resistance allows its use with a wide variety of gases and liquids."

Shear Strength (MPa) 12

Maybe its not thixo after it cures...

"Permabond HH190
Anaerobic Gasket Maker
An anaerobic curing flange sealant that can replace, or be used as a dressing for, conventional pre-cut gaskets. Since the HH190 is a flowable paste, it conforms to the shape of the flange. The consistency allows metal to metal contact of the flanges while filling the areas where no contact exists because if irregularities. HH190 results in uniform stress distribution and eliminates the need for re-torquing because of stress relaxation of the flange bolts. It provides instant seal depending on the gap and flange width and ultimate seal up to 5000 psi. Because of the flexible nature of the cured polymer, HH190 has good vibration and shock resistance. HH190 provides convenience of assembly and is easy to dis-assemble as well."

Shear Strength (MPa) 12

VS.

Loctite 515
Shear Strength (N/mm2) 6

anyone got the conversion for millipascals to newtons per mm2?

This gets beyond me... the Permabond might be stronger but i dunno how to choose one over the other. seems like the HH190 is for filling the gaps where the standard gasket can mate with the surfaces adequately, but it also can replace gaskets. Why use a gasket anymore?

the anaerobic bit worries me; what happens if it gets oxygen?

up to 5000psi once fully cured sounds good!

did notice that all of these are only good to 150 celsius (300 farenheit)... is that good enough?

stop?

[ChrisC]

So what you're saying is that if you have a thixotropic anaerobic paste, formed in situ with the stress relaxation of the flange bolts, then you will not shrink or creep until the convenience of the assembly has a reduced capacity for stock holding.

Yea, that's the ticket....now I got it

[creeper]

Sounds like a Honda manual from the 60s.

[meat popsicle]

yeah, i work with punchcards... or did ya forget?

chris, you lost me at the second sentence

So what you're saying is that if you have a thixotropic anaerobic paste

yeah...

formed in situ with the stress relaxation of the flange bolts,

in situ, yeah but flange bolts add stress so i dont find this relaxing...

then you will not shrink or creep until the convenience of the assembly has a reduced capacity for stock holding.

no shrinkage or creeping - funny how those go together

951170 is unavailable. So I'm left with Tornado G1, which is very similar, other than costing TWICE as much. Or I can go with the MSP3 rallye cam and springs and wind up around the same cost as 951170, except with perhaps too much cam.

There are other cam options too, including getting mine welded up by webcam.

Does it come with a cool sticker?

I hear certain stickers are good for a few ponypowers.

I can't do it! That's too much money for the same thing. And the rallye cam is sure to break me in half. So I'll keep looking for a 951170, or check if megacyclecam will make one, or buy a stocker and get it welded up by webcam.
