2013 yz125 problems

Hey Guys, i have a 2013 yz125. which has had this problem since i bought it last year. The bike does not have a power band. I have two other yz125 and this one is really slow. here is a list of what i have done so far.
1. new air filter
2. new spark plug
3. went leaner on the lectron carb
4. checked power valves work just fine, also cleaned
5. new wiseco top end rebuild kit installed correctly, piston is not installed backwards
6.new crank seals left and right
7. new reeds
8.repacked the silencer
9.tried on a cdi, stator, magneto, and ignition coil of a 2006

i still have this problem, its super annoying. any suggestion or help would be greatly appreciated!!
