JohanC Posted November 16, 2009 Share Posted November 16, 2009 Lately i've been hearing this strange winning noice when the Bird is cold, (2004 F1). Typical noice is that of a overworked differential in a motor car. The noice goes away when clutch is engaded, but re-appears once the clutch is released. Seems that the noice is louder, or more noticable, when bike is not up to running temperature. I am planning a long trip within the near future and would like to know if the is anything i have to worry about. The bike has got 25 000km's on the clock and both the sprockets and chain were replaced less than 5 000km's ago. Tyres are in good condition and nothing else seems to be a issue. Bike is running normal. Please advise. Thanks, Quote Link to comment Share on other sites More sharing options...

JohanC Posted November 17, 2009 Author Share Posted November 17, 2009 what oil are you using? Am running a semi sintetic make from Castrol 20W/40. Quote Link to comment Share on other sites More sharing options...
Mekanix Posted November 17, 2009 Share Posted November 17, 2009 Was going to say clutch plate chatter, but that doesn't whine. My chatter went away when I started using Mobil 1 synthetic for bikes. It comes and goes but is much quieter. Are you using a motorcycle formulated oil or car stuff? That might be the source/problem? I've only used motorcycle oil in my bikes, don't know what car oil would do to it if anything. Quote Link to comment Share on other sites More sharing options...

Peepa Posted November 17, 2009 Share Posted November 17, 2009 Another thing you mite want to look into is that your oil might be to thick upon starting the bike in colder weather. The first number in to oil is its start up weight. Try going with a 5w40 instead and see if that takes care of it Quote Link to comment Share on other sites More sharing options...
