Hi every body! Newbie post and I'll warn you now that I'm clueless when it comes to bikes. I just ride it. I got my Piaggio Liberty 125 serviced last week and the day later it wouldn't start. I had rode it 15 mins earlier. Eventually it started and then the next morning for work, it wouldn't start. When I finished work and now, it still won't start. I've spoke to several people and they said it's the starter motor. Also the engine air filter was caked in dirt. Should this be cleaned under a service? I have been having small problems with this for a while, but it would always start eventually. It makes a noise as if something is turning, but it doesnt start at all. Sorry for the lack of knowledge.
