Hopefully, the pictures uploads are fixed for the time being. Let me know if you continue to have issues. I am looking into a more permanent solution. Thanks for your patience. - Makotosun

WTB: MX250A Piston Ring was created by Mike MPD

I was lucky enough to score a brand new nos cylinder knowing that standard bore pistons are cheap and plentiful.

I overlooked the fact that standard bore piston rings are hard to find. 

Willing to purchase complete piston with ring also but really just need the ring.

Let me know!

Enduronut may have the ring or can help if maybe something else will work...  like one ring from a DT set or something?

If Enduronut doesn’t have any you can get 1st over and file the ends carefully to spec. We would do that at Butler’s Yamaha sometimes if they were backordered

Something like this should be good but expensive. Should be lots of compatable piston kits out there that would work from other 70mm yamaha reed models.

Does anyone have good contact info for enduronut? The forum says I can't PM him. I tried the email function but haven't heard back. Maybe he's just busy.
