Go 1 tooth up on the rear sprocket and add 10mm oil to the fork height.

When was the last compression test run? What was the reading?
When was the carb last cleaned? Did you reset the float height?
When was the crank seals last changed?
Have you replaced the exhaust gasket?
What fuel mix are you running? Is it fresh?

I would check for a broken reed or fuel leaking in to the cylinder. Those are easy and you can do both at the same time.

Remove carb and leave the fuel hooked up. See if it's leaking out the front of the carb.
While carb is out take flashlight and look inside at the reeds. Make sure none are broken anywhere.

Get back to us.
