Bike died load bang have compression but won't start

Really you need to investigate what went wrong. Sounds more like an ignition fault than engine rebuild.
But your description is so vague it really could be anything.
Sounds like you need to investigate it properly.
There are people on eBay rebuilding these engines for like Ā£200, which is a pretty good price. Can't see the components being top quality. Wrong time of year to be having a Ā£200 expense mind you.

Check the triangle first before asking .... check the plug and spark and ht lead .... check for contamination in fuel although unlikely.... but as Callum so rightly suggested if it was poping or backfiring it sounds like an ignition fault or a stator fault ...

When you say it has compression is that with a gauge or just thumb over plug hole? A mates bike had very similar symptoms, could feel compression with your thumb, gauge only showed 25psi though. On taking barrel off piston rings were in pieces and barrel heavily scored. Amazed it even had 25psi!

When you say you felt like 5th had gone how so? Was the bike easy to start back up after the garage stop?

@declan Started first kick at the garage stop carried on a died was pulling back.through the gears and acting biggy not a fouled plug as it's in a bike shop not im guessing electrical but nowing my luck top ends gone

If there is any corrosion on any of them, then give em a good clean and apply a blob of vaseline to stop em rusting in the future. If something is not earthed or shorting out that would give you problems for-sure.

Definitely check what caused the bike to fail. They don't just fail.
If it's lack of maintenance, then I'd be checking that bottom end for tolerances.

I've seen the pins that stop the rings rotating on the piston move, allowing the ring to spin and open end catch on a port. With it being under load at time it failed (going up a steep hill), I wouldn't be surprised if piston expanded due to heat build up and pinched the rings. May have been running on the lean side aswell.
