Excuse me for my English but I have no idea of the mechanic lingo. I recently bought a second hand R9 scooter, but because of the cold weather the electric start wasn't working ok, I started usind the manual one. But it was loose, and everytime I kicked it, the edges that transmitted the torque from the pedal to the engine jumped and bruhed a little bit, now they're almost worn out and the manual start is no longer working.
Can I change this part of the bike, or have a mechanic come to the university to fix it? I hadn't taken it to the mechanic yet so I don't no any.
Any help will be greatly appreciated. Thanks!
