Hyosung backfiring

[AllanB]

I have a horrid feeling that Gun Gum stuff dries hard and is not flexiable - if so it will not work for long.


You want a small tuber of Permatex Ultra Black Gasket Maker.

Description: Maintains a higher resistance to extreme temperatures while sealing in exhaust.

Two Brothers Racing recommend it when repacking their cans.

+1 for that. I had an exhaust leak a while ago. Had the same problems with back firing and could hear the dirty ticking, turned out to be a snapped exhaust stud

[DarkLord]

Cheers chaps.

I shall keep an eye on it and if the stuff I've put on comes off, I'll get the stuff you have mentioned. Where do you get it from?

[CookMySock]

Or you could weld the hole up.

Steve

Sounds like the logical thing to do

It's not a hole it's the slip join for the new muffler - just needs a bit of goo
Super Cheap Auto sell it.

[DarkLord]

Nah it wasn't the slip join - there was a hairline crack right around the lower part of the header. I've got some stuff called Gun Gum which I've stuck all over the crack and it seems to have done the job.

Instead of a nuclear apocalypse I now get a pleasant snap crackle pop while decelerating.

Sweet. If it gives you any more shit, bring it over and I'll deal to it with the MIG.

Do you have welding gear, DB?

If so perhaps you could help with the inner part of the header pipe - it's come loose and is bouncing around inside the outer pipe. Makes a helluva racket. Apparently to fix it you need to cut a hole in the outer pipe and weld the outer and inner pipes together to keep it still, but I don't have the gear to do that...

Yeah bro I got a little workshop MIG. It's surprisingly powerful, on little jobs anyway.

I have exactly the same problem here with one of our GT250R's. It's rattling like a stone in a tin can. Probably the thing to do is use the drill to cut a hole about 8-10mm diameter, and then weld the baffle inside to the outer shell. It's easy to weld the hole shut again, but not so easy to know where to drill to start with. I should probably attempt my one first, before I have a go on your exhaust, but if you're still keen to be the guinea pig then rock on over.

Cheers. You're in Tauranga ay? My folks live there, so I'll give you a yell next time I'm over catching up with them. I don't mind being the guinea pig, got a fairly good idea where the rattle is anyway. Plus I've seen it done on other parts of my header pipes before, and it's worked.

[AllanB]

Sheezzzz in that case weld the sucker and be done with it

I'm in Edgecumbe, which is about an hour east of Tauranga, or an hour north of Rotorua.

Yeah I know where the rattly thing is, but its a bit of a gamble drilling a hole and finding an edge to weld down. We'll just do the kiwi thing and give it a burst.

I'll put ya on my contact list, and just pm or txt me when you are gunna be nearby and we'll see what we can arrange.
