Bought my first ktm two weeks ago. Before I rode it I tore it apart and did the exhaust, smog, jd jet w/red, and 13/50 gearing. All I can say is wow, am I glad I bought this bike. Starting w/ electric feels weak, may need to do that mod soon. Not far off my '07 kx450f super moto as far as power and a lot better than my drz 400 sm w/ distanzias that I was riding off road, that's an accident waiting to happen. It over heated on my first ride so I ordered a fan kit. Oil level was high after riding, tried lower in the window this time. Also need a rear spring. I'm 130 w/out gear, rider sag is at 105mm and static is at about 52mm. Guessing I need to go w/ a lighter spring. Can someone direct me to what rate and where to get it, having a hard time finding what I need. Not wanting to do the front springs quite yet. Anyway, nothing like a bike that'll pull a 4th gear power stand up wheelie at 60+ mph. What a blast this bike is, I love it.
