How does decel valve work on Honda Shadow ACE Tourer?
When the decel valve opens it allows a small amount of fuel into the cylinder to prevent backfiring. I have fixed these on many Hondas previously. When stored without a fuel stabilizer these will plug up as easily as the idle jets. They usually plug in the vacuum passage through the small o-ring on the cover plate.
What causes backfiring on Honda Shadow ACE Tourer?
Backfiring is caused by the ignition of fuel and air in the INTAKE stream causing it to fire through the CARB. The popping on decel is caused by a lean fuel mixture being ignited by the spark on the exhaust stroke. The air cut off valve is there to assist in richening the mixture by reducing the amount of air in the mix.
Where does extra fuel go in a Honda Shadow Ace?
In most Hondas like the “T” the extra fuel is injected thru the same port as the choke circuit. The valve cover is about the size of a quarter with two tabs sticking out at about 9 and 2 o’clock with two screws. Loosen the screws while holding the cover because there is a spring behind it. Also keep an eye out for the oring on the vacuum port.

Why is my V twin motorcycle only firing on one cylinder?
When a V twin motorcycle is running only on one cylinder, or bikes with 3 or more cylinders with a misfire, it is oftentimes one of two issues: fuel is not being delivered into the combustion chamber, or there is no spark to ignite fuel due to a handful of causes.
What to do if one cylinder of a motorcycle is firing?
Note the condition as any damages should be repaired to limit the chance of future issues. The up side is that if 1 cylinder is firing, it would be quite uncommon for there to be an ignition coil issue as there is already a functioning lead going to 1 or more spark plugs. A simple thing to check is the spark plug boot.
Why does my motorcycle not fire at full throttle?
A float tends to get stuck easily if a carb has enough build up. Blocked jets. There could be a blockage in one of the jets causing the bike not to fire at idle, half throttle, full throttle.
