Boogaloo Dan Posted November 4, 2011 Share Posted November 4, 2011 Hi, everyone, Picked up my 2009 YBR 250 from local dealers and noticed on way home a distinct but not very loud metallic vibration at between 3.5 and 5k revs., accompanied by an irregular knocking. It's not there when I take the bike through this rev range when it's not in gear. I can't go any higher up the rev range as the bike has only done 75 miles so needs running in. I suspect something's not right with the transmission. It still has dealer warranty so I'm not too worried. Anyone out there got any ideas? Do I need to take it back to the dealers?

Moderator Airhead Posted November 4, 2011 Moderator Share Posted November 4, 2011 I would Dan, you need to get it investigated. Link to comment Share on other sites More sharing options...
whythedevilnot Posted November 12, 2011 Share Posted November 12, 2011 Have you had it investigated yet? What was the result. Sounds like you bike has had a long stand and I believe that can cause something bad to happen to ball/roller bearings. Link to comment Share on other sites More sharing options...
