RXE 250 Sprocket seal popping out.

[Blackhawk7188]

So it's weird that's it's happened twice now. About 5k miles on my RXE 250 and it just started leaking oil out of nowhere. Checked the the seal behind the front sprocket was pushed out. I pushed it back in and seemed fine. 2 days later and it popped out again.

Think it's just a worn out seal or something else? I am going to order a seal on Amazon to eliminate the worn out part of it. The TT250 seems to take a 34x20x7 in that position so going to go with that as I have a Zongshen too.

Any suggestions are appreciated.
