Hi, I have got an MBK booster for my boy Dan the gamer when he turns 16 in January. It has had a problem with the forks and i cannot seem to find the correct forkseals ( 2 sets and it still leaks!!!!) Does anyone have the correct part number for the seals please? I also have a Haynes ped man but this does not show the type of amount of fork oil i need to add!its a great bike , nice to take out . Thanks for any assistance .Tony
