time for a new piston

now, it's time you try and figure out what went wrong...just that time, lean jetting, airleak, ect, ect. so it doesnt happen again
 
she's fried !!!!!!,
but still do a leak test if ya have one to see uf thats what happened
and pics of carnage are a must !!!!!
 
WATER!!! Sooo, the piston is'nt hurt? Could you have sucked some water in while riding. If so, Water in a cylinder is very, very bad. It will hydraulic and bad things will happen.
 
If you have studs missing, you need to take that to a machione shop and see if he can fix it. Do the right or if done wrong, you can be in the same place a week from now, go ahead and have him bore and hone it (buy piston and rings first)...
