1. The 99 - 03 R* have a transmission recall out. It is a safety recall and Yamaha will repair the problem at no cost you. A cir-clip in the trans can come loose and lock the trans up. The engine has to be torn down to fix it. Contact any dealer local to you and give them the VIN number and they can check the database and tell you if the recall has been done. If it hasn't been done then have them do it. You don't have to be the original owner. Any question just open a new thread and we will give you more information.

2. The front pulley nut on the R*'s are known to back off from reverse torque. The 99 - 05 models have a tab washer that has one tab bent over the nut. It doesn't hold very well and the nut can back off. The 06 and newer they did away with the tab washer and put a conical washer under the nut and changed the nut to have a flange that is staked into a channel on the shaft. It is also found not to hold very well on some but is better than the older tabbed version. If the nut comes off you will not be able to move the bike under its own power. The splines in the front pulley and the output shaft can be stripped. There is no recall on this and it is up to you to check and fix it. If you want more information on this open a thread and we will answer your question.
