My 2011 KTM 250sxf performance has gone down hill. I'm losing half the power it has, I'm going into 3rd gear in corners and when I come out it has no power. It Boggs into 4th and even then it takes for ever for the power to hit, and when it does it's already asking to be shifted into another gear. It has no throttle response like a fuel injected bike should. It's really hard to kick. It's idle is off a bit also. I recently got a new top end done on it. Also we cleaned the fuel injector and still nothing has changed.
-When was the last time you rode the bike when I had, "full power"?
-Could it be bad gas?
-Did you change that mini cone gas filter screen? It's between the fuel line and the EFI.
-Airfilter clean?
-Airbox clean?
-Spark plug?
-Spark plug cap connected well?
I'm not sure if that bike has a filter at the bottom of the gas tank or fuel pump?

an amp draw test can work almost as well (but must know reference draw
of known good bike). I am not familiar with the fuel injected KTM's but we
often run into internal fuel filters being clogged, leaking internal o-rings or
hoses as well as a bad fuel pump on occasion with other brands of bikes.
Also check valve clearances and replace the cam chain if it has some time on it.

like a 2T with carburator problems, how did you solve the problem? Was the tank filter? Inyector?
Thanks in advance.
