Hi, I have a 2004 KTM 125sx I recently got it fully rebuilt after a seizer and now its happened again after 5 hours. It was broken in fully. Basically I was 4-5 minutes into Weston Beach Race and the bike bogged down then locked up. After taking the head and the jug off I found the piston was okay but there was a lot of metal shavings and the bottom end had locked up I took some photos. I have attached them to the thread. Does anyone have any ideas of what has happened?
