What happens when you give a bike throttle?
I have a 2006 yz250f that has sat since 2009. Recently, I cleaned it up and drained the old gas out of it. I put fresh gas in it and kicked it over and let it run at idle for about 10 minutes. After I let it warm up, I gave it some throttle and it dies on me.
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.
What kind of engine dies when throttle is applied?
Idles good… dies when throttle is applied??? Got an 86’ Bayou 300. Starts good, idles fine, but when I attempt to apply any throttle, it dies. Any ideas? Thanks. plugged jet in carb, remove bowl and remove jets and use fine wire or small drill bit to clean out port in jet Click to expand…
What happens when you touch the throttle on a Kawasaki?
I start it, it idles ok, I can apply throttle and rev the engine just fine for the first couple of minutes, and then, after that, it wants to die if I touch the throttle. It seems to be consistent; whenever the engine is cold, it runs fine for a couple of minutes. After the engine warms up a bit….
What to do if your bike Idles but bogs with throttle?
I will look during tomorrow times. If it idles fine but it bogs down with throttle, your high speed gas jet is probably clogged. Clean your carb and spray carb cleaner in all small passages, make sure air can flow through all ports no matter how small. Put it back together and it should run great.

What’s the idle speed on a Yamaha bike?
The bike hasn’t been running to my knowledge for 4-5 months. Prior to my purchase the previous owner, a friend, said he cleaned the carbs. Basically, she’ll start up fine and idle around 1500-2000 rpm (full choke) but upon going to 1/2 choke or giving her any throttle, she dies.
Why does my bike not start when I give it throttle?
Check the carb diaphrams. If there is a slit of hole in the diaphram (s) the needle will not lift (giving it more fuel) when you roll on the throttle. Hold the diaphram up to a very bright light and look carefully. Also, if the air passages running up to the diaphram chamber are blocked, the slide will not lift.
Why does my motorcycle bog when I open the throttle fast?
When the bike is at an idle, it will bog if you open the throttle all the way to fast. It is still rideable but sometimes when it happens it is always at the wrong time. My plug is lightly oily and black.
Where is the slow speed jet on a bike?
Remove the float bowl and the slow speed jet is located next to the main jet, remove it and look thru the center you want to be able to look thru it (like a baby telescope) and see thru it cleanly and clearly. You can refer to a shop manual, parts manual, or possibly owners manual.
Why does the round slide on my Yamaha die?
The round slide seems pretty stout, but the diaphragm that controls its operation could get a tear in it and cause it not to operate right. There are lots of pinholes in the needle jet that clog up easily. The main jet is a pretty big hole that wouldn’t clog too easily, and mainly just limits the flow at full WOT.
Why does my bike die when I give it throttle?
Check for an air leak allowing too much oxygen into the combustion chamber. Check the condition of the spark plugs to see if the fuel mixture is too rich or too lean. Nope, not yet. Still working on it. It’s doing BETTER, but it’s still doing it sometimes. I’m thinking mixture. If you go half choke on yours does it rev up better?
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.
Why does my bike die when given the slightest?
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. See my reply to the other comment for a more detailed explanation.
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.
