thanks for the info and the PM.
i did not look thoroughly enough underneath the scooter to locate the leak, i relied on the information provided to me by the mechanic that tested my scooter for me before i purchased it.
yet, when i took the water pump apart - i could see that there was a leak from the oil seal.
i replaced both seals (inner one and the oil seal)
now, after everything is done - i could look beneath the scooter to locate another leak of oil -
now it looks like it is coming from the center of the engine - there's this metal protector underneath the engine, and it looks like the leak is coming right from the bolt in the center of that protector.
i will upload the pictures of the process and i can demonstrate when it is coming from.
