i bought my yz426 almost a month ago now. iv'e got only a few questions. How long does it take to break in the bike? which gears/how hard can i ride it during break in. and also i checked my manuel and it shows the Maintenance Intervals. and it shows checking the valve clerance and all that after break in. when you all bought your bikes new from a dealership. did they check all that for you for free after break in? a few of my buddys got yz250f's from a diff dealership than me and they got all the maintenance done for them for free after break in IE: adjusting the valves/oil change and all of that.
