Hey all...
Just getting back into ridin dirt again (bout 11 years off) and just bought a 95 KTM 250 exc to put around on with my step-son.
Bike was owned before by someone in NH who rode many enduro and hare-scrambles. Has extra cap gas tank....after market pipe and silencer (not sure what kind).
Bike runs great at low-low mid rpm range. Pulls like a tank. BUT has nothing on top. Held wide open...sputters and coughs, like its still cold. Air filter (twin air) was a LITTLE dirty...not bad. Noticed some oil or something comming from front of exhaust...like the gasket was leaking...could this do it? or am I lookin at carb issues. I really dont have much knowledge about re-jetting and stuff. SOmeone else told me mabye power valve stuck open?? or something. Any ideas?
Replaced reeds....ones that were in the bike (carbon fibre) were kinda torn up and there was a gap the width of a credit card on both sides of reed cage. New FMF silencer....other one was kinda trashed. Runs a little better...but still sputters out on top. 175 main jet...air screw 1 1/2 out. Not sure about stock settings. help?
