Small Honda Dirtbike (XR80, XR100) - Ignition Timing and Valve Clearance

About: Personality of a potatoe... not really.

Just do your first engine work and don't know how to re-time your motor? Learn how to set your cam timing.

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.
