Why does my motorcycle die when I turn the choke on?
However, you start it up on choke and everything is fine until you turn the choke off, and the engine dies. What gives? This is a classic symptom of a partially or fully clogged pilot jet. Fuel goes bad after time, and the first circuit/jet to clog with varnished up fuel is the pilot jet.
Why does your motorcycle only run on choke?
Fuel goes bad after time, and the first circuit/jet to clog with varnished up fuel is the pilot jet. This circuit delivers fuel for idle, and has the smallest passages found in carburetors.
What causes a motorcycle to stall at idle?
Or, you could have air leaking around the throttle, just enough to lean it out at idle; the mounting boots could be the leak, or diaphragms in the carbs, that kind of thing. Wow, thanks both of you! I will try these things when my mechanic manual comes for this bike, the owners manual is like “here is the start button, a durr.”
What should I do if my bike is stalling?
What you might be doing with the choke is trying to keep the bike running,and that is a job better done with the idle stop screw. Try to increase the idle with this screw, and hopefully the bike will at least run without using the choke.
What are the symptoms of rich carb settings on a motorcycle?
Rich Reduced Power – It has less power but seems to be OK and runs. Reduced Fuel Mileage – Your using more fuel per cycle so your mileage becomes worse. Rough Idle – Combustion takes a just a bit longer with more fuel and at lower RPM’s the engine can idle rough.

Why does my bike stall when I switch gears?
When the bike is actually rolling there doesn’t seem to be too much of a problem, except that it stalls when you switch gears unless you have the choke in a bit (this bike, you can never turn off the choke or it stalls immediately) otherwise the bike stalls even if you are giving it gas.
Why are my carburetors not working on my motorcycle?
Fixing Lean Mixtures. This condition is generally caused by the incorrect fitting of after-market accessories such as exhaust systems, air filter systems, or replacement carburetors of a different type or size. In addition, if the fuel level in the float chamber is set too low, insufficient fuel will be drawn through the main jet.
