Default 2011 EC250 Died

Hello

Bought this from a member on here

2011 EC250

Just been fully rebuild, barrel replated, wiseco piston, carb rebuild

It started fine when I bought it
I ran it up my garden

In the morning started first kick and I ran it down the street at about 20mph nothing mental it then spluttered, internally backfired and died

It?s getting a spark
I?ve removed the carb, jets and cleaned it all
Checked the floats
Checked cables to cdi unit
Changed the plug
Changed the fuel
Tried bumping it (just bogs and doesn?t give anything)
Removed the manifold and there was a few spoonfuls of fuel(black)
Left the plug out and kicked it over a dozen times
It you kick it on full throttle it will backfire occasionally
Tried a spoonful of fuel down the cylinder with the fuel off and nothing
Checked the piston and liner as much as you can and it looks Ok
Seems to have compression

I?m at my wits end with it, absolutely gutted I?ve just got it and this has happened.

Going to drop it to a bike shop Tuesday but ideally would
Like to sort it myself

Like I mentioned on TT, check that woodruff key. That's something you can do yourself, for free, if you have the flywheel puller already.

So the plot thickens

Woodruff key was broken
But the flywheel/crank has inner and out movement of more than 5mm
Vertical movement also

It would appear the bearings have failed.
Absolutely gutted.

I work for a bearings company so does anyone happen to have the bearing part numbers for the crank cases?

Seals obviously will be damaged.

But once back together will be reliable. My left main failed at 11 years. That's not bad going for a competition bike.
