I just bought a '01 KTM 250 E/XC. It has 102 miles on it now and is starting to run a little slower instead of opening up. I have never owned a 2-storke before this so take it easy on me. There is tons of black spooge running out the spark arrester and when ever the rpm's start to get very high, maybe 3/4 up, it gets all garbled. It's ok if it's WOT but when the engine catches up with all the gas going in it startes to stumble. The dealer told me that i will need to lean it out because it comes to rich from the factory. What do i need to change in the jetting, how much and should it spooge like that? Also, what else needs to be done to finish breaking it in, besides, changing oil, clean air filter. Thanks
