I have a 2000 400, and the petcock has leaked since i have owned it in the ON postion only, so I just rode it in RES. Well now it leaks in reserve too. So, is there anyway to fix this, or do I need a whole new petcock?If so, anybody got a second hand one? In an unrelated matter my throttle stays WFO, and won't snap back closed, the grip is not rubbing on the handguard, and I see no mud/dirt packed into the throttle tube. Any ideas, besides, lubing the cable?
