Check your welds

[isaac_]

Anyone else running the cat on the akra? Check your welds. Anyone else cracking? Or have cracked?

Manufacturing flaw? Or did I just get a bad one?

Tried to fix mine and well... we screws up. Need the take to a better welder.

And ktm will only sell a full system? Can't buy the cat separately. Grr.

I can't believe, Akra too can have QC issues[emoji15][emoji15][emoji15]

I can't believe you took an arc welder to that...

*I* didn't do anything other than take it to someone I thought could weld it.

I'm going to attempt to get this repaired by a solid welder. Let me get back to you?

That guy owes you a new one...

That needs to be tig welded and to do it right it needs to be taken off of the bike.

Yup. To both. I think he tried 28 amps and he was still heating up the cat faster than the rod.

Also, it's off the bike. In the picture, it's resting on top of the air box.

Okay, cool. Did you find out what kind of metal it is? I'm betting it's Stainless. A good tig welder can fix you right up but don't be surprised if it cracks again right next to the weld, pretty common.

Yup. Stainless.

I need to figure out what rules my race org is going to go with next year before I source a back up mid pipe. I agree the crack is likely to come back in a different spot.

Have a mid pipe made like the new "open'"Akra, better front side/mid-range gains, less weight etc. Don't bother fooling with that one anymore.

I'm limited to what I can do per my race org. we're required to run the cat.

For stainless you'll want to go 1 amp per 0.001" max. I usually start at about 70% of that, and work my way up until I'm happy with the penetration and puddle I'm getting. 28A for that was (obviously!) too much, but "heating up the cat faster than the rod" implies to me he was then what, STICK welding it??? You can TIG aluminum foil together... I've done it. (stupid fabrication tricks to do after everyones had a few too many sorta thing) but seriously... for something like that, you want to start LOW on the Amp and work UP, not start HIGH and go "Ooops, blew a hold in it! Guess I better turn it down!" Your 'welder' seems... ... ... ... ...inexperienced.
