put a new piston in my bike and now it wont start. i am trying to start it without the airfilter on could this be the reason

was it a standard piston?

make sure you still have compresssion ,

if youve only changed the piston , cant really see what else it could be other than distubance in the cylinder head and compression loss

did yo renew the gaskets or just re-use the old ones?
