My son has a problem with his balls. Not hereditary, I know very well how many balls I have and need! Now I have not looked at his because I'm not at home right now, but according to the RD125B_RD200B repair manual, which I have, there should be 19 balls both in the upper and lower bearing of the stearing head. He says he can't understand that because it doesn't look like more than 18 will fit each. The problem is that he has split two heads at the same time, one parts bike and his own bike, and he may have mixed up the balls. Sounds rather uncomfortable to me, to continue the (bad) jokes. But he thinks he has 37 balls from his own bike, and they should be OK. Then he may have dropped one on the floor and can't find it, so it may have been 38 originally. But is it possible that there are 18 balls in one bearing and 19 in the other? And which one is what?
Or would it be smarter to buy replacement taper bearings?
