Took the piston out and looked at it and no problems found exhaust valve was extremely burnt cleaned it and put it back in again with new seals and still smokes a lot
Next check I'd do is Fuel correct then Spark Plug, if still then Check for a broken or miss aligned ring.
Note:
If the exhaust smoke is blue or gray: Thick blue or gray smoke is an indication of the vehicle burning oil, which means that oil is somehow leaking into your engine'scombustion chamber.
If you have wrong fuel say have 2cycle mix and put in a 4cycle you'll get fouling too.
Hope I helped

You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.
SOURCE: white, blue smoke from exhaust
sorry to spoil your day but white exhaust indicates that you have a blown head gasket or the head and/or the block is cracked

try running redex through the system then change the fuel filter to rule out a blocked line
