Your dirtbike is hard to start or back fires? Learn how to set your valve clearance.
The bike used in this example was a 1998 Honda XR80R but will also apply to the Honda XR100 as well.
I feel that this makes a good instructable since the XR80 and XR100 is extremely common as a first dirtbike. Since many people are learning to ride on one of these, they are also learning to maintain and service a bike as well.
