Why does my motorcycle die when the choke is on?

Why does my motorcycle die when the choke is 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 my motorcycle only run with the choke on?

It means your motorcycle is not getting enough fuel, and this can be caused by dirty or clogged pilot jets, clogged fuel line, clogged fuel filter, dirty petcock, loss of vacuum in the carburetors, among other carburetor issues. Nine times out of ten the cause is clogged pilot jets.

Why does my motorcycle die when I start it?

The bike also dies whenever I press the choke in while it’s warmed up, even slightly. I tried starting the bike with the choke and it’ll work until it warms up a little bit, then anything after that kills it. This never happened before, only just now.

What causes a motorcycle to stall at idle?

Extremely lean motors can also stall out completely when given some light throttle. Another sign of lean running is the “hunting idle” where the motorcycle revs up randomly, changes RPMs, or takes forever to come down to idle.

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.

What causes a pit bike engine to sputter?

The problem of having an engine “sputter” is typically caused by a fuel system issue. For pit bikes with smaller cc displacement engines, in order for a cylinder to fire efficiently, three separate components must work together; the fuel delivery system (carburetor), the ignition coil and wires and the spark plug.

The bike also dies whenever I press the choke in while it’s warmed up, even slightly. I tried starting the bike with the choke and it’ll work until it warms up a little bit, then anything after that kills it. This never happened before, only just now.

What makes the combustion chamber of a motorcycle sputter?

The three things you need to create an explosion in the combustion chamber of a motorcycle are air, fuel, and a spark. Examining the mechanics that deal with these three components will ensure you’ll find your sputtering issue. I’ll discuss the most common reasons for sputtering.
