Recently i had changed the fork oil and seal of my yamaha sz-rr. but after some 100 odd kms there is a leak from the front fork seal. right now my friend is using the bike and he has send some pictures of it. i am attaching it here. when he showed it to another mechanic from his place, the mechanic said to replace the fork seal and fork oil. how did this happen? the first mechanic said he used original fork seal and oil. and now the second mechanic is saying the first one used low quality products and it has to be changed before causing more damage to the stem
i don't know whom to trust now. please help find the truth about this situation.
