That’s insane. I’m assuming from the fact that you are posting that you are relatively uninjured? Glad you’re ok.

If the wrist pin bearing and stuff was in the exhaust, it might’ve been the circlip that came off, but the piston and head should’ve been scratched up. The head shouldn’t have broke under any circumstance. I’ve locked up soooo many two strokes and have never seen a head do that. When you rebuild, I would suggest an aftermarket head like vhm.

These are brand new bikes, taken apart and sold as parts, I’ll try and find a link to his eBay page, but he posts on here as well. Mav ~ help me out here… he’s posted on the for sale section several times.

We have a 300 kit in my practice bike, the problem is I cracked my case and the bottom end is done, so we need a complete new everything

Also perfect opportunity to drop a 300 kit on it since you need all those parts anyway.

The good/bad news is that there’s a couple guys parting out brand new bikes and even at the proud price they are asking, it’ll be cheaper and way less of a headache to rebuild yours.

From the cracks around the head, it looks like the top of the piston collided with the bottom of the head around the squish band, it's likely the bottom end or con rod failed.

This is a carb bike, not a TBI bike. There is no known issue with piston to crank contact on the carb bikes. Also when the piston does contact the crank it does not usually present in this manner (head blown off). My initial guess is this is more likely a rod failure.

What does the top of the piston and bottom of the head look like?

If there is any intake skirt left measure the thickness of it versus the original piston. Vertex had a quality control issue with some pistons. It was talked about in the 300SX thread. The inside of the skirt can hit the crank. Maybe the 250 as well?

It was scary hahaha, happened in the air right when I went to rev it before I hit the ground, it made the gnarliest sound ever, sounded like every bolt in my bike just exploded out
