Namura piston kits?
I just put a namura piston kit in my ktm150sx 2010 and blew a ring. Piece of the ring chipped off.1/2 inch piece. It scarred the top of the piston and bottom of the head. THANK GOODNESS my jug was clean! I had it replated uhhhhhh 4 hours ago! Piston blew the ring at 4 hours.... Don't use namura. Ima go with vertex since that is the stock piston for this bike. Gotta flush out the cases wih diesel as well for any
