i took off the left side engine cover to check my whatcha ma doodle. i don't know the technical term for the metal bowl thing that bolts to the crank and has four magnets attached to it. bear with me, i am new to the 2 stroke mechanics of motorcyles. anyway i pulled it off and one of the four magnets had separated from the housing and another on had broke in half. i came to the conclusion that this is why my bike is backfiring when i try to kickstart it and it is also why my bike won't idle. has this ever happened to anyone else or am i the only unlucky rmx 250 owner in the world.
