Hi All, My new moped runs now. I'm SOOO excited, this is my first moped. It's smooooth. Hey I need an on off right handle bar switch. The one on the bike has the knob broken off, came without it. I don't want to jury-rig a knob, looking for the whole switch. No horn, no light. 1978 1.5 model. THANK YOU SO MUCH FOR YOUR HELP!!!
