Older bikes that had carburetors could, if there was a problem with the float, allow gas to continuously fill and overflow the float bowl, leading to a large puddle of gas under your bike. To fix this, a shutoff valve was added. However, it is very easy to forget to turn off the valve after a ride, leading to the same issue.

A vacuum operated switch was added to the valve that would only allow fuel to flow when there was suction, provided by the carb, which fixed this issue.

Now since all Sportsters are made with fuel-injected engines, there is no need for the valve switch since an exact volume of gas is squirted into the cylinder. It does not use gravity to feed gas like the older carb-built engines.

Why doesnt harley put a reverse gear on touring models?

Harley-Davidson typically doesn't include a reverse gear on touring models primarily due to the traditional design and engineering philosophy behind their motorcycles, which emphasizes simplicity and classic styling. Additionally, the weight and size of touring bikes can make a reverse gear less practical, as most riders can maneuver these bikes with techniques such as walking them backward. Instead, Harley offers accessories like electric reverse systems on certain models to assist with parking and maneuvering in tight spaces.

Where can you get replacement seals for softail shocks?

any harley dealership or reputable bike shops that carry harley parts. you will need the bushings and bolts and fluid also. It doesnt pay to just replace the seals. While you are there change it all.

Where is the fuel shutoff override switch located in a 95 Toyota Camry?

Have you tired basic tune up? Change the spark plugs, air filters, and PCV Valve... if that doesnt work, I dont know.. Mine needs an air fuel ratio sensor which causes the plugs to foul up.. That in turn causes my car to hesitate and choke out when you push the gas.
