There are a number of mechanical components that could cause starting problems with Yamaha's R6 motorcycle. This includes a blown fuse, a discharged or damaged battery, inadequate fuel levels or problems with the spark plugs.


Something as simple as a blown fuse can prevent the YZF-R6 from starting. The R6 takes a 50 amp main fuse located beneath the cycle's seat.


A discharged or damaged battery could also prevent the R6 starter from working. The bike requires a 12 volt, 8.6 ampere-hour battery. The periodic maintenance section of the R6 manual details how to remove, clean, and charge the cycle's battery.


Always check the fuel gauge when troubleshooting R6 starting problems. If the fuel tank is empty, refill it with fresh, unleaded gasoline. Yamaha recommends premium grade gasoline for the YZF-R6.

Spark Plugs

The spark plugs are some of the most important components to a functioning ignition system. Remove, examine, and adjust the spark plugs if the R6 won't start. This motorcycle requires two NGK CR10EK plugs in each of its cylinders. Set each spark plug's gap to between 0.024 inches and 0.028 inches.
