G'day fellow Thumper Talkers, I am from the WR side but I ride a blue thumper so I hope you can help. After nearly 3500km's, my rear wheel bearings are beginning to wear. I priced "genuine" yamaha bearings and it totals Aus$114!!! I plan to buy the bearings from a bearing supply but need the code stamped on the side of the bearing housing. I don't have access to my bike because it is stored two hours away from where I live and my manual is with the bike. I wanted to replace the bearings for this weekends ride but it is impossible for me to get the numbers before then. If anyone has the an old set of bearings lying out in the shed or access to their manual, please check the number for me. Thanks. Grum.
