i ran my 400 out of gas last weekend when i was riding. the cam chain has been ticking real bad then got worse before it stoped all day because the tensioner spring broke so i got pulled home and today i fixed my tentioner permanetly and put gas in it and it will not start. it feels like it has no compression. could it be the compression release on the cam or did i blow the rings. it also was over full of oil in the oil tank
