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!!

Check exhaust for holes? Check exhaust for extreme build up on the inside? Does it have a longer silencer than the others?

So you're saying this bike is not producing the power the other two are? What's different? The mention of Lectron carb jumps out at me. Not because the Lectron is inherently bad, just that it's different than stock and if not set up property, may have something to do with non-standard performance.

DUDE:

MOVE THE LECTRON TO ONE OF YOUR OTHER FINE RUNNING YZ 125's AND SEE IF THE PROBLEM IS MANIFESTED ON THE OTHER BIKE TO SEE IF IT IS THE LECTRON. NOT A GENIUS MOVE THERE.

ALSO PLEASE POST YOUR PROBLEMS IN THE TECH HELP/RACE SHOP.

I gave you some suggestions in your first thread. Not trying to be an asshole (that comes naturally to me).

Hey luis97:

Sorry to have busted your butt so hard. It is just that you already had one thread going, and many folks gave their time via comments/troubleshooting.

The Tech Help/Race Shop is the best place to post bike problems. You'll likely get more comments that way.

So again, please accept my apologies.
