My buddy has a 2011 Apex with 900 miles. The sled would only tach 9400 when he got it now it will only tach 9800 no matter bhow long you hold it open. My 2012 would only tach 9800 new but @500miles I started to see10,200 and higher on big runs. I can't believe this motor is taking this long to break in---any similar results??
