im about to purchase a 06 crf 450 from a buddy for 5000.00. bike is very clean and has about 10 hours on it. Comes with original plastic (like new), paddle tire and a few other small items. Bike has been sitting for about 6 months in his basement before i fired it up this afternoon. Question is when i started the bike and was waiting for it to warm up i heard this squeak noise coming somewhere from around the motor, so i got down and was watching and listening and i heard it 3 or 4 more times. By the second time i found that it was coming from the transmission and when it squeaked i could see the front sprocket twitch forward a little. WEIRD (almost like it was in gear and i was slowly letting the clutch out). Or almost like a dry bearing or clutch pad. Is this the start to some sort of future problem? Or is this mabee from sitting with out being ran for months. I then rode the bike and everything seemed normal from then on out. brought the bike back and let it idle for about 60 seconds and sounded normal.
