How can I check if my Honda motorcycle still runs?
Once the idle and midrange mixture are dialed in, the high-speed mix may be checked. The high-speed jet is checked while the bike is being driven. Speed the engine up to between 3/4 and full throttle with the bike in first gear. Listen for a lean misfire and observe the exhaust for excessive hydrocarbons.
What does a lean misfire on a Honda motorcycle mean?
A lean misfire indicates that the midrange jet is too small and must be increased at least one size. White exhaust gas indicates excessive free hydrocarbons (unburned fuel), and a too-large jet that must be decreased by at least one size.

How does a Honda carburetor adjust idle speed?

Why does my bike idle but not die?
This is a classic and very obvious clogged pilot jet. If you can start and idle fine, but slowly rolling on the throttle bogs/dies, that’s the culprit. If you can make it through the bog and then it suddenly roars to life, that’s also a really big confirmation as well.
Why does my Honda Shadow not run at idle?

How does the idle screw work on a Honda?
The Idle screw adjust the thottle plate (s) to increase or decrease engine speed at Idle. The Idle mixture screw or pilot screws adjust the air/fuel mixture from Idle rpm to about 1/8th throttle. Adjusting the mixture screw can affect idle speed, thus requiring adjustment of the Idle screw.
Is the Honda Shadow 1100 still in production?
If Honda were still making the Shadow 1100, 1997 would be its 13th year of production, and the 11th in essentially the same configuration.
