Do these need to be replaced now that my pipes are off? I have just cleaned them and there was a whole lot of carbon packed in the gap within the metal ring - not sure if there was a rubber o-ring or something in there. Thanks for any advice.
p.s. Picked up a new (used) cylinder head for $20 so now just waiting on a rebuild kit from Tyga... _________________ '87 MC16
They can be reused if they aren't too compressed. You can usually use them a number of times over.
Don't worry, there's no o-ring that's supposed to live inside them!
It won't hurt to use a little high temperature RTV sealant on them for good measure when you reassemble the exhausts. _________________ Andy.

RTV (room temperature vulcanized) just means it cures in open air at normal temps, this one claims to go to 300*c. _________________ Please do not PM me technical questions, if you can't find it on the Forum start a thread
Because of the location, I think it is better to use a "high temperature" RTV silicone sealant. Here in the States at least, Permatex makes one that is widely available at auto parts stores. A moto-shop that caters to dirt bikes would also likely have something suitable. Hope that helps. _________________ -Jim

I'll find out soon enough because i am not taking the exhausts off again. _________________ MC21SP - Roth-tax

You guys have so little faith! Isn't that what the gasket is there for in the first place? If you look closely these rings look to be bimetallic - I'm guessing the copper inner portion would expand under heat (more so than Aluminium) and produce a very good seal. Why put on extra sealant that just has to be cleaned off the next time you pull the pipes off? _________________ '87 MC16
Ahh but i fitted new ones as my old ones leaked and new ones are quite cheap but the new ones leaked,yes i did fit them poperley and cleaned up the exuausts and barrels.I should have used sealant in the first place

I don't think they were genuine Honda ones then! The Honda ones are about UK£12 each!
That ain't cheap in my book, not for a bloody exhaust gasket! _________________ Andy.

I got them from Apex(it was before you could supply NSR parts )and they were Honda ones ,they were nice and shiny and came in little Honda bags ,and yes i think they were about £12 each,i din'nt think that was a bad price but sealer would have been cheaper
