I've noticed that these 900 seem to have a deadly sputter that will put you over the handlebars! Riding along, Get on it WOT, then off it and right back into it, sorta a laggy/boggy spot in it! It seems to fall flat on it's face for a split second. Myself and Skattum both noticed it. Anybody else run into this? Know what it is? Know how to fix it?
