It's a piston copy of a factory piston.It's amazing just how much damage those tiny ring pins can cause...Looks like a mini grenade went off in the cylinder...lol.

You DO NOT want to damage that ceramic lining in that cylinder, a honer would file all that away as well.They do make flex hones in 52mm. Maybe that would smooth out the port edges?
Don't know if you saw, but I'm not the OP. Just wanted to show my cylinder that failed in the same way, and if anyone has recommendations on how to prevent it. They do make flex hones in 52mm. Maybe that would smooth out the port edges?
Like Damien said, do not hone it, it will destroy the lining and render the cylinder unusable.You DO NOT want to damage that ceramic lining in that cylinder, a honer would file all that away as well.
I figured that the ceramic is very hard and wouldn't sand off easy, but would hopefully take off any burrs. I didn't consider how thick the ceramic is though.You can actually hone the cylinder, but it is a risky proposition. They are honed from the factory.
Need a 52mm flex hone, they exist for the cr125. This one.
The ceramic is very hard. The risk is around the port edges and potentially delaminating the ceramic liner if it has any damage or a weak adhesion to the aluminum under it.I figured that the ceramic is very hard and wouldn't sand off easy, but would hopefully take off any burrs.

You maybe right. I thought the eBay post said v3 but it does not. Here’s a pic of pistonThe position of the upper transfers and width of the intake port inside the cylinder makes that a V2 top end. Have a picture of the piston, specifically the windows?
If I remember right the large piston ports are V2You maybe right. I thought the eBay post said v3 but it does not. Here’s a pic of piston

Yep...That is no newer than V-2...I can't tell ya if V-1 was the same or not though.If I remember right the large piston ports are V2
If I order a new cylinder and piston, is that going to be v3Yep...That is no newer than V-2...I can't tell ya if V-1 was the same or not though.
how can you tell? It looks the same as the add on their website?The position of the upper transfers and width of the intake port inside the cylinder makes that a V2 top end. Have a picture of the piston, specifically the windows?
