My 78 Puch Maxi has a disturbing amount of slop/play in the steering/fork head tube. Essentially, when I stop, I can feel the entire top of the steering move forward a bit. I'm sure it's just a couple milimeters or so, but it freaks me out. I purchased a new bearing set from Treatland, got it all installed, only to still have the same problem. Even with all the new parts, the main tube coming up through the fork yolk/triple tree is shifting back and forth when braking.
There is a top tapered "washer" that looks like it should hold it firm with the top nut on firmly, but that is not the case.
What's the solution to this? Do I need a new top triple tree/yoke, or a new tapered washer? Or should I try to shim it?
