Faults:

The Yamaha 450 has been a great bike.

At around the 7000 mile mark, the TPS sensor on the carb went out (bike still ran, but had "low" power).

At the 10,500 mile mark, the pulsar unit on the stator failed (had to replace the entire stator unit).

General Comments:

The WR is a great bike, and once you get it "dialed" in for your weight-style, it handles nice.

Fantastic bike for the value, and highly recommended.
