I'm trading my low hour 03 YZ450 for a KTM 250SX this Friday. I've never owned a Katoom. Are there any issues associated with this year and model? I have done my own wrenching since I was 9 and I'm 43 now so I can fix pretty much anything. I just wanted to get back to a two stroke and I don't think any company knows two strokes like KTM.
