On my 2000 Tomos Targa (which is now destroyed) I noticed something that was bugging me, but I never asked about it.
On the left side off the moped, on the kick start area where the kickstart enters the engine, there were a couple of gaskets or more like rubber spacers. When I first noticed them, they were already kind of mashed up and ended up falling off.
A while later I noticed oil spatters on my sneaker, my left sneaker, and when I'd touch around the bottom of the machine I would find some oil too.. I never did locate the source of the leak, but I would have had to sooner or later.
another less important quirk:
The kickstart cover always slides off (you know the rubber sleeve) that's a different problem but it bugged me as well.... I was going to epoxy it back on... any better ideas..?
