Hi Everyone ... hoping someone might be kind enough to hopefully shed some light on a peculiar something with my recently aquired '08 CBR125R;

2008 Honda CBR125R, fuel injected, 1900kms on odometer. Bought pre-owned 2 weeks ago, very good condition. Past weekend performed oil-change with Castrol motorcycle specific 10W-40 motor oil and adjusted clutch at lever to allow slightly more freeplay. Since, when engaging starter, it emits a "squeal" like noise just as engine catches and starts. This sounds peculiar? Did not exhibit this symptom when I bought Bike. Might this be an indication of a problem?

Any help/advice provided is deeply appreciated!
