has anyone ever seen the gear break on the water pump? its an 05 250. the bike died and lost fire so westarted tearing it apart and niticed a tooth to a gear cought between the flywheel and the stator. we had ended up tearing the clutch side of the motor apart and discovering that 3 teeth of the water pump gear were missing. we have split the cases since then and havent relly found out why the gear broke. everything else seems to be ok. any advice??
