"OK, getting the petcock this week. got a few other problems. A: I need a helmet ( Half helmet) but the new ones today are not the type I am looking for. I am looking for one that is about as large as a baseball cap. not those big things that go over your ears! I know they where available in the 80's I dunno about know. Anyone know where to get them? B: the variator, My dad has a few questions about it 1: How often do you need to get in it and clean/grease 2: What kind of grease gun tip do you use, ours doesn't fit it 3: how often do you have to grease it. the grease part looks like a ball point pen tip. you press down a ball, and grease comes out, i want to get grease in, but I don't have the right tip to the gun."
