Super Moto Exhaust Repair

[Powerstrokinit]

So a friend of mine calls and said his Wife bought him a Husky Super Moto bike for Christmas, but the exhaust is cracked and was wondering if I could weld it. It is stainless, so we pulled it apart and I TIGed it up. Turned out decent I think.

how's it going, the material is titainium. Ican tell by the color of the bead. the weld looks good and all but it's not. it will hold for awhile and crack riht beside the weld. i've welded lots of four stroke ti exhausts for guys ice racing up here . the only way to weld that is in a chamber. when you finish welding ti should have a mirror finish to it if it was shielded correctly. hope that helps. i admire you for trying to weld it and doing such a good job.

If you wind repairing it again for him, build a chamber with a card board box and some tape with a piece of plastic or glass to see through, or just keep Ar flowing into the box while you weld. Not very scientific but it has been done in a pinch. The boxed in area only needs to give enough room for you to manuver in and seal up the area to be welded in if you can purge the pipe before hand. I first learned this from Wyatt Swaim, who runs the Tig Depot site, at a seminar a few years ago. Good Luck, Jeff

If it is Ti. it will crack but I think it is Stainless

guys,

have a closer look at the pics, all the factory welds were clearly made under atmospheric conditions with inferior shielding compared to the tig repair- it's not Ti.

FWIW titanium can be welded without a chamber- a trailing shield fitted to the torch (as well as a purge) will work fine for some applications.

[Powerstrokinit]

The stock welds look like they are MIG welds, so that is why I figured it was stainless. Is there a way to tell the difference between the two?

hey powerstrokinit,

titanium has almost half the density of stainless steels. if you pick up an exhaust made of titanium it would be spookily light.

[FusionKing]

Factory down the street welded Ti in the air for years. My boss did it and he said they cut their own filler by shearing little strips.

[bob_e95482]

Hit with a grinder- Ti makes super bright white sparks.

pete, the bike is a husqvarna super motard which comes with ti exhaust (at least here in canada. pro circuit also makes ti exhaust all of the mig welds are made in atmosphere for whatever reason (probably to keep costs down and speed up prduction . so that is why i think it's ti. Jef

BTW, that weld looks beautimous. Must be the machine. Ha!

Its all in the machine!:cool:

I've been roadracing for quite a few years and replaced/repaired many exhaust systems. When a mfg. says they have a "TI" system, it usually means the exhaust canister and maybe the internals of the chamber are TI, the rest is usually stainless.

As someone else mentioned, hit it with a grinder and see if it sparks white (TI) or yellow (stainless).

Nice looking welds.

I just bought a used Dialarc HF and hope to be making some nice looking stainless beads like that soon.

sorry to be off subject here, but whats with the street tires on a super-moto bike ??

[FABMAN]

but the welds look great.....

[MintSScout]

Also off subject, what year is your POWERSTROKE.

[Powerstrokinit]

Isn't that what a Super Moto bike is, dirt bike with street tires and big brakes? Mabey I am calling it the wrong thing.

My Powerstroke is a '97.

Thanks for looking.

Actually the term is " Super Motard " or one word " Supermotard ".

Dirt bikes with street tires raced on road. Take the knobbie off a dirt bike and put on a good pair of street treads and you can get into racing rather cheaply.

Here is a quote from a good web page on the topic.

Even with only a change from knobbies to street tires, Yamaha's YZ250 motocross bike makes a great Supermotard mount.

HONDA calls it what it was at the beginning ...

TOKYO, Japan, March 16, 2005 - Honda Motor Co., Ltd. announced the introduction of the XR400 Motard, a Super Motard-style* sport bike equipped with an air-cooled, single-cylinder, 400 cc, OHC, 4-stroke engine and 17" on-road front and rear tires. The XR400 Motard goes on sale in Japan on Tuesday, March 29.

I guess the AMA had an issue with " tard " being somewhere in the name.

It all started out as Super Motard before AMA even recognized it as a class.

Oh well ... the AMA has gone " PC " ( Politically Correct ) :D

Peersonally I am not a member of the " PC " crowd. Guess I am too old!

Actually there are tons of SuperMOTARD sites around ....

Super Motard since 1970 http://www.bikez.com/category/index.php?category=8

It's an interesting riding sport .... taking a dirt bike and racing it on asphalt.

[Powerstrokinit]

I thought I heard Motard and Moto, but didn't want to sound like a retard if it was wrong. Thanks for clearing it up.

Whelp, no being in moto-x since '83(woods riding only till a few yrs ago) and never heard of that Honda scoot, but that isn't supprizing, when I was stationed over there in the early '60s seems Joe would create a new scoot every mo. I assumed it was an acronym for Super Moto-X since it is about half MX, thanks for clearing up the question, but I really like the sport unforunately not much TV coverage.
Keep the right side up.

sure enough you are right. i guess i am behind the times. LOL. i was thinking super moto CROSS. once again i learned something new on this site. sorry about that powerstrokinit.....

[Powerstrokinit]

Shoot, I didn't even know if I was right, so we both learned something.

It's not just Honda ... I think the only maker not building a Supermotard bike would be Harley Davidson ( no surprise here - if they are smart they wont even attempt one, as it surely would not do well - think of thier attemps at motocross in the 1970's ) ... even Suzuki has an offering in thier 400 cc line. :eek: My brother has one of these, it's a really fun bike to ride. Personally I ride a DL-650, it's a hybrid street/off road bike leaning more to street riding. Ducati makes one.

This all started out with a few riders putting road tires on dirt bikes, once it was seen as becoming a big thing the bike manufacturers started building motoard ready bikes.

i can't believe they go to the expense of using Ti and then cut so many corners with the welding. i can understand the use of mig but argon can't be a large overhead for a mass production company :confused:

any idea how long they last before failing? (probably just until the warrenty expires :rolleyes:)

happy new year all

[drewworm]

Super moto is that new fangled racing hybrid - half dirt, half street with racers from all walks: Motocross, gp, heck probably even trials riders. It's kind of answering the question of who the best rider is overall.
