Fall prep is nothing more than getting ready to ride. Take a good long look at the machine from the front and work your way back. Most mechanical problems should have been fixed as they happened or prior to spring storage, but there is always a chance something was overlooked. Lights, controls, and suspension are all common areas for wear and broken parts. Open the hood and check the drive belt for wear or flat spots. Replace the belt now while its warm and you’re not out on some semi-deserted trail in the dark! Also pay close attention to the pull start cord as these will break from wear and using the manual emergency cord is absolutely no fun in sub-zero temperatures. Your tool kit should be checked for completeness, including a spare spark plug and drive belt.
A few items to check include:
Air Intake: Make sure nothing has clogged your intake
Throttle: Squeeze the throttle and make sure it moves freely
Brake: Squeeze the brake lever to ensure it works properly and does not go all the way to the handlebar grip
