Let me tell you the story
Picked up my KTM 150 at Christmas and it's been a great bike all winter had no problem with it on my field, that all changed on april 16th. Decided to get away from my field and venture to one of my local tracks, it's a sand track but not stupidly deep, it ran fine the first session then two laps into the second session it stopped instantly. I knew the bike had ceased, and was surprised that after 8 hours of riding it had blown up. Got home that day and took the bike apart, the piston was badly damaged and that's all. I was advised to put a bigger jet in so I swapped the standard 182 to a 185.
after that the bike ran fine the next 2 weeks then just last sunday the bike blew up again 3 laps into practice, the dirt type was loamy.
what is going on why is it ceasing up? please help!!!
