hi there just wondering if there is somebody who could give me a little bit of advice i was travelling down the road at a high speed when my back wheel locked up and cut out and came to a standstill proceeded to try and start it it turns fine just dosnt fire and yes there is spark there was a smell of burning water if that makes any sense but has not lost any fluids really hoping it may be a simple fix

looks like you blew your engine. get the barrel off and have a look maybe its just the rings gone and have a look at the barrel for scores. dont keep trying to start your bike you will just do more damage.

If anything it'll be the top unless you were doing 100 mph flat out for 20 minutes. But the top would have broken before those 20 minutes pass anyway,m so yeah, top end

Do a compression test before you strip it, but it sounds like a classic seizure. Assuming it is you'll need to pull the top end down to see, you'll probably need a piston kit and a barrel. Head should be ok, and but sure to check for vertical play in the con rod while you have it pulled apart.
Don't try to reuse gaskets.

The "burning water" smell is a bit of a worry. Only thing that would smell like that is head gasket failure, but to smell it you need to have the bike running and warmed up.
