I've ridden for quite some time and I've been able to get my 600 up on accident and on purpose... its difficult to do it just double pumpin it.. but then again more then likely you pop the clutch your gunna crash n burn... the times I popped it up on accident I was racing and popped the clutch... ...just my story.. still can't get it to budge in second gear.... ...still need jet kit and timing advancer... pipe moved the power band to the higher rpms...
