Exhaust gasket dimensions

[Gabriel]

Does anyone know what a 250ES exhaust gasket measures on the ID?

I have a 300EX on hand and it measures 1.365. It might work but is a little loose for my liking. Looking for a donut ring that's about 1.25 ID.
For all I know the Honda 200 gasket may be the right one but I used the last one I had and haven't ordered more.

If you have one laying around, please measure it and let me know. Thank you!!

86/87 200x- is this: 258843 not sure it’ll help but u can compare part #’s
If it the gasket your looking for/ just remember the soft copper squishes so the one you have will most likely be fine.

If you don't mind china made for this part, I can get them pretty cheap. I could grab a hand full of them in my next order if you want. Ironically, this company does somewhat good giving dimentions and such, everything is in mm though, 32mm = 1.25984in. They have smaller that's under 1.25in too, and even smaller yet. I suspect the best measurement you'd need is the exhaust flange that you're trying to seal, so the ID's don't interfere with the exhaust flow.
