Noobi,
quick tip if you're changin oil on a 125 gasser over the w/end - when she's drained use this time to undo the two bolts holding on the front sprocket/chain guard (if you do this with oil in you will end up with a small slick on the garage floor
) remove the guard and the clutch secondary cylinder ( this is all obvious when looking at the bike - don't fret) you will now have access to check the front sprocket retaining bolt - check it, give all that area a bit of a clean - check the clutch line at that end - lube the front sprocket etc, etc - put everything back together ( dont overtighten) then fill her up with 750cc of above mentioned good oil - go rip 
don't forget to repeat often.
