Hi Josh, I´ve owned my Pantah for many years and not experienced the wiggle you refer to. My Pantah went down once when my friend got the clutch wrong on take-off. After that I discovered a looseness in the rear swing arm assembly. I had some bronze swing arm bushings machined to replace the original ones. They tightened things up a bit. I would first check the air pressure in the tires and the rear dampers. If those are OK, then maybe the steering head bearings need adjustment or replacing. I try to do most of my own wrenching, but a good working relationship with a local dealer is a good idea too. I´m currently trying to locate a replacement for the right hand (front cylinder) exhaust header pipe. I hope that helps. Chris
