Can't find the crush ring for the DG exhaust....... any material or solution will sort this out?

Thanks,
Jacky

if you mean in the exhaust port,muffler centres keep a range of circular flange gasket rings in odd sizes,might be  a tad thick for tooeys,but check anyway if theres one close to you, :P

Jacky,try Repco. Recently needed exhaust gaskets and after trying every bike shop in town I finally tried them. Showed the guy the old gasket,he went out the back and returned with a handful. "How many do you need?" was his reply.  Can't hurt to try them

But the stock crush ring is too big for the DG's exhaust flange.

Hey Mick, Jacky's just learning mate. He hasn't even started to fossilize yet. He's only 15 ;D

I sold seven of my bikes in the past year. We need fresh blood, if I am to have any chance of selling the rest ;D

Welcome aboard Jacky and good luck with your exhaust mate :)

Hey Jacky ....I take it your talking about the IT250K??, I just used High heat copper silicone on mine........the standard ring never seals that good even on a new stock exhaust. Just make sure you clean the surfaces with prepsol or brake cleaner etc first

BTW these are not a flange gasket......more a spigot gasket, an o ring would be more effective perhaps

Yeah ITDOG, I'm talking about my IT250K

What did you do to stop the DG pipe leaking?

How did you spray the pipe to make it shiny and nice??

It's a nice bike. I have one in similar condition. Better than the new bikes.

In the pipe at the step that sits up against the exhaust port, let it sit for about 1/2 hour or so to form a skin then fit to the bike. I do that to my CZ & it's perfectly sealed, my YZ465 which has a DG exhaust needs to be done every few rides though otherwise starts leaking again.
I had to shorten the piece that sits over the exhaust on mine as it was way too long

And let it cure for 24 hours before you try and start it.
