2 days ago I was ridin' my KDX, not a problem in the world.. a few minutes later it seized en then got loose again, offcourse with no compression at all
![Rolling Eyes :roll:](./images/smilies/icon_rolleyes.gif)
The thing I find kinda strange is that my cylinder has been plated a month ago with new piston and new gaskets from that company (Powerseal here in the Netherlands), I didn't ride it a lot the last weeks so I didn't even used a full tank of gas..
Here are some pics of my cylinder and piston, maybe you guys know why it seized?

Normaly the reason is quite clear for me but now i realy don't know...
The jetting is fine, even a bit rich.
I use Putoline MX7 motocross oil with a fuel oil ratio of 1:40 (25ml of oil in 1 litre of gas)
I was ridin it in so I didn't even ripp it that much
the radiators were a normal temperature and the bike didn't real feel hot like a normal seizure..(is this the correct word?)
I bought a new BR8es spark plug, same as one that was in there when I bought the bike.
crank shaft is 100%, no play on the bearings or on the bigend bearing.
no signes of detonation or something like that.
My cylinderhead wasn't leaking, no white smoke or dirty coolant (clear green)
so... can you guys figure this out?
