my buddy has the same 1987 125 force i do he called me over to look at his it had a bad sounding knock in it we did a compression test everything was good there i asked him when it started happening he said after cleaning the carbs and tank he then put new gas in and a can of sea foam then just shortly after that the knocked appeard so i was a little confused and after a few minutes of thinking about it i asked how much gas was in it he said about 6ltrs i figured we would put some more gas in and see if maybe there was too much sea foam we put 60 more ltrs in it and started the motor for a few seconds it sputtered and had a slight knock but then just like that the motor smoothed out knock went away and she purrrrrrred again now runs smooth i guess this is a leason learned the question is has anyone had this happen to them. just wondering
