I can't imagine that muffler shields are very rare for these bikes but I'd imagine they get into rough shape pretty easy, I can work with pretty rough condition for the right price I'm more worried about completeness than quality.
The side covers I know are a bit coveted and I only need one side but am willing to work with someone who understandably doesn't want to split a pair. Again I'd consider the wrong color for the right price.
Then the rubber boot that joins the airbox to the carb, mines gone hard and I'd like a fresher one.
Last thing I guess I can throw in would be the rubber strap for the battery, I can make something work easy but I like original.
