Hi there, 
I just picked up a 1998 320 pampera.  Neat little bike!  I got it to keep up with the kids who are just getting into trials.   
I have a few questions.   
- under the nuts on the rear axle, there are just 2 big flat washers on each side.  Does that sound right?  It seems to me there should be something like a step spacer, or something because the washers don't really make contact with the aluminum tensioner piece inside of the swingarm. 
- where is the turn signal flasher relay in this bike?  (yes it's still street legal)  Is it integrated into the  module somehow. 
- where can I find plastics for this bike, are they still available through the GG dealer network?  I need a new headlight bezel and rear fender.
