Here's my 1977
This one was given to me as well. I'm gathering parts to restore it and have about everything I need. Now that Villageidiot has explained to just use panty hose for a filter I'll go ahead and buy an airbox. Those filter screens must be non existant, I see a lot of air boxes for sale but none have the screen or the damper tube. I guess you might have to rejet with that setup? It is VERY hard not to start case matching, big jug, cdi and all of that, but I'm just going to try to get it box stock except for the crank, I just don't trust a con rod with a brass bushing instead of a bearing. I will probably be PMing you guys if I run into problems, there is no way I'm going to endure the (very knowledgeable) kids at mopedarmy.
