As I've mentioned on one or two threads I've just acquired a Lifan 250P. The bike and I are not licenced yet so its no on-road antics for us yet. The first time I took it for a spin around the apartment complex I discovered it has a very noisy squeak from the front disc - if I tap the brake it goes away momentarily. I can't take it out on the road for a burn to try and wear out the squeak so any suggestions?

A second question about engine oil. It's a couple of years since I last owned a petrol powered 2 wheeler so what oil should I be using? I've never bought engine oil in China and the bike is brand new. Suggestions?
