Whining noise
 

Hey guys just picked up an 02 bird, chain was shot replaced with rk530 chain and new rear sproket, it makes a squeaky kind of noise coming from front sproket area only under load. Doesn't happen while coasting or clutch pulled in and only happens after about 60km/h.. and I'm unsure if it happened before as I replaced the chain straight away, any help would be great cheers

Maybe the front sprocket needs changing too.

Does the chain and sprocket size match?

Hopefully it's not more serious like a bearing or something.

Front sproket is good same pitch, it does sound like a dry bearing noise the bike hasn't had much use been sitting around for ages any idea what bearing it might be ?
