Anyone fitted a AHL 300cc kit to a klx250s efi model?

Hi all. Deep down I know it's a stupid idea. But it is a very tempting one. You can buy a 292cc big bore kit for next to nothing from china. Going through all the trouble of getting the efi to work is probably not worth the effort?

What's the chance of bottom end damage if that piston fails?

I've read reports of people fitting a 260cc injector, bolting the kit on and fitting a nice exhaust with no problems. But surely can't be that simple. Would be nice to have a bit more torque.
