Hey guys I have new DG exhaust and it leaks from the exhaust flange! I have put copper coat at the seal and it seems to work! What do you guys do, can you get an aftermarket exhaust flange for the 84? Thanks.

not to my knowledge. All two stroke exhaust flanges seep oil to some degree.
I use high temp silicone o-rings on my 85 250r with stock flange and it hasent leaked .I have several races on it. You would have to get smaller o-rings for the aircooled R.

I goop them up with hi-temp RTV - usually the red stuff.
I use 2 on mine. 1 on the groove and 1 on the front.

I was skeptical at first, but it seems to last a while.
I used the RTV on my 85 250R about 3 years ago when I had the top end off and my Tecate about 2 years ago when I first got it. Neither leak now.
Admittedly, I only get about 4 or 5 good riding weekends a year so this might not be a good sample.
I rode the everlovingdogcrap out of my 82 and 85 and they both leaked with new gaskets and 1211 bond, it's a nature of the beast. The exhaust temps get so high there is no way a paper gasket and metal ring will completely seal that opening with expanding temperatures. That said, once I got my double o-ring flange for my 85 from esr, it surprisingly stopped most if not all the oil splooge. Unfortunately they don't offer one for the 81-84. The idea from atc 300r above just might work.
Thanks for the advice boys appreciate it! Might buy o rings and see down the track! This is what I've put on it, seems to be ok for now and not leaking
