This is your problem. It runs terrible right from the factory. Don't second guess the decades of experience here on the forum. Unless you feeled compelled to go through a extremely long and frustrating learning curve.
Follow the sticky's at the top of the forum, and uncork and rejet.
thanks, I went riding this weekend on it, and you just flat can't get it tuned in smooth with the current jetting...nothing seemed to work for low throttle settings. I've got a JD kit on order, and will be uncorking the exhaust and doing the free mods....you all have been very helpful through this learning curve and it's REALLY appreciated! This bike is a beast, it's really too much for the single track we were doing yesterday (never got out of second).
I thought initially this may be a cheaper sport to be in than other forms of motorcycling....after my first day on the trail I would say that's not true. I'm sore, and need a few replacements because trees don't give all too well
