:?: I just got a new Z400. I've heard you should only ride 1/2 throttle for the first 10 hours (that's really hard to do), but the dealer that sold it to me said to just ride it like normal from the get go. So far I've only been able to ride it for about 30 minutes total. About 5 to ten minute intervals. I went ahead and screwed in the throttle screw so I would only go half throttle, but I still got on it a little bit. How important is this?
