2006 EC300 problem

[fury1]

okay I have search for similar problems here and there are plenty
my bike is running like the choke is always on,it wont clean out or rev out,it has no power at all from 3/4 to full throttle
the top end has very lttle time on it,it has plenty of compression and has a heavy kick to start it(compared to my 200)
heres what I have tried:

*changed plug
*fresh fuel
*repacked silencer and checked for blockages
*burnt out pipe and checked for blockages
*changed air filter
*cleaned carb four of five times
*changed carb from 200 with same results
*tried dropping the needle to lean it out
*swapped CDI from 200
*removed both powervalve covers checking for opening

few things I will be trying:

*swapping out coil and plug wire from 200
*checking reeds
*disconnecting kill switch
*taking off the tank and looking for a broken wire?

any ideas? am I overlooking something simple?
Bike ran fine at our last enduro in November,
took it apart last month to replace kicker gears and now
I have this problem

*could it be a magneto problem
