The only real changed I did right off the bat was to install some Fast Co Flex bars.
I have not had a 250 2 stroke since 2006, when I had a KTM 250 XC. The power of the YZ surprised me at first. I could see where it could easily get me into trouble once I got tired. The revalved suspension from EVO was magic. The previous owner was close to my size and weight....so it seemed to work great. We reset the sag to 105mm and I immediately felt at home on it. I am way to out of shape at this point to fiddle with much........just need some seat time.
After the first night on it I order a G2 throttle tube and installed it with the 300 cam. Huge improvement.
The thing runs soo good I have not even looked at what is in it for jetting. Runs nice and crisp throughout the throttle range.
Next step will be a FWW I think. I had a Rekluse in the 250F, and it has taught me some bad habits. I am having an issue with stalling it coming into corners. Getting on the brakes before I have the clutch in far enough. Working through that.....but I think the FWW will help the stalling and tame the hit even more.
Really happy with the amount of power everywhere. Bike has a 49t on it. Was thinking a 50t would help me use 3rd a little more.
