Red means stop. The first thing to remember if a dashboard car warning light comes on while driving is not to panic. If it’s red, it means there’s a safety issue or something is seriously wrong with your car.

That little lite is telling you something is wrong with the bike. With the Ignition switch off, put the bike into the “run” position, then turn on the ignition. This should put your bike into diagnostics mode. Use the “Trip” switch to cycle through the codes.

To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC’s the code will be displayed or the word “none” will appear if there are no DTC’s. Push the odometer reset button again to view additional codes if they exist.

To determine your actual speed, you divide the number of minutes it takes you to drive the distance into 60 (the number of minutes in an hour) and then multiply this figure by the distance you traveled.

Getting a Speedometer Calibrated Most auto-mechanics perform speedometer calibrations, and some driving schools perform them as well. The cost is usually approximately $75.

For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling.

As a general rule, bigger wheels result in a rougher ride. Switching to a smaller wheel and a thicker tire can give you a smoother ride without any major modifications to your car. When changing the car’s original wheels and tires, the general rule of thumb is that you can go up or down by one inch.

While larger-diameter wheels and tires should improve handling and high-speed performance, lower-profile tires also tend to have a firmer ride and may be noisier than the smaller, standard rubber. Bigger wheels cost more money. The bigger you go, the more expensive the wheels and tires.
