[KEVIN132]

ok my sons bike just stopped . it wont kick over it stops.
well i drained all oils no metal.
it turns over at allen plug but at certain point it just stops!!!!
ahhgggg!!

is it the main????

i hope its just a valve issue????:scary: :confused:

if it goes so far fine and just stops in sounds like something is hittin the piston. Possibly have a bent valve??? or sucked something through the intake somehow?? my 04 backed the bolt out of the filter once and sucked it in and it done the same thing
