Not to sound like a ****, but have you thought about the Hot start button located on the carburator. It's the Big red button. try doing some research. Once it fires push it back in quickly. All it does is feed more air into the engine and less fuel.

Car wont start when warm


It always helps to tell us what you are working on. Could be bad coolant temp sensor; bad coil or module (these heat up after you turn hot engine off); improper fuel pressure (test with gauge); leaky injector(s).

Won't idle at low speed


greetings anon.
hot and cold engine ? ill assume hot only.
but runs ok with fast right foot???? ILL ASSUME YES!
idle regulation has vast numbers of reasons for failing so ill list the physics.. only..
ill reduce this to simple

1: engine misfires so bad it can idle.
2:ISC regulator stuck closed, or fails for above.
3:EGR stuck open. and makes ISC seem bad but is not.

The ISC is and idle speed control system.
it can not raise idle if engine is running super bad
it cant do that, it can only add air.
in a servo loop system.

so a savvy mech, uses his right foot. to prove this
in 1sec flat (i call it the happy foot)
if i can raise idle easy, it's iSC messing up.
if i can't the engine runs bad.

easy no?

ever get a tuneup this decade?

99 sprint st wont start or turn over horn out as well


Take your battery out and bring it to a local parts store or bike shop to have it load tested. If a battery is sulfated it will often show full voltage however there will not be enough amperage available for large loads.

I just got my bike a couple days ago and it'll crank but it's so hard how do you use the decompression lever? Would I need a spark plug cuz it should fire rite up.


Standard starting procedure for YZ400/426/450 is as follows: Push the engine around using the kick starter until you hit the compression stroke. The kick starter will get impossibly hard to push at this point. Now pull in the decomp lever and push the kick starter down a fraction, and I mean a FRACTION. This is where most people go wrong, they push it down too far with the decomp lever pulled in. Now give it a full kick without throttle and it should start.

The above should work fine for a motor that's already warm and was NOT stalled. If the motor stalls it will usually need the hot start button opened as well to let extra air in and bleed out the fuel that usually gets stuck in the motor when it stalls.

For cold starts, you will need to put the choke on, and if it's really cold you might need to prime the engine with a twist of throttle to get the accelerator pump to shoot some fuel in before you start.

As a general rule, NEVER twist the throttle while kicking when you are actually attempting to start the bike, it won't help at all. Also, having your idle screw adjusted correctly makes all of this a lot more easier. Standard setting is usually 1.5 turns out but it should be set to give the smoothest idle you can get using the minimum number of turns out from all the way in. If you have to wind your screw right out to get a good idle you need a bigger pilot jet. Conversely if you have to wind it most of the way in (less than 1 turn) you need a smaller pilot jet. I'm not sure about the 450 but my YZ426 came standard with a 42 pilot jet and changing to a 45 made it idle and start MUCH better. Incidentally the WR model uses a 48.

Bike wont kick start or idle , it will coast


first drain the carby, then set your air mixture screw 2 turns out, from the fully turned in position. The starting proceedure is as follows, when the engine is COLD, turn on fuel, pull on the choke fully, and kick the engine over. DO NOT use any throttle, when the engine is cold, and the choke is on. Remember Choke on, NO throttle.
When warm, no choke, and a little throttle when kicking.

My rmz 250 wont start on the first kick when the choke is on but when the engine is on and hot it starts first kick with no choke?????????


It takes a little suction for the gas to reach the cylinder from the carb. When it is hot and on, the gas is readily available. So a kick or two, when cold starting is not abnormal. Alternatively, kick twice with the key in off position. Then turn the key on and kick, the engine will start instantly. Idea is the make the gas reach the inlet.

89 dodge shadow. hard start. normal idle cold, fast idle warm. sometimes it wont start until i hear fuel pump activate.


Hello,
The car may be hard to start because it may need a normal tune-up. If the spark plugs are pretty used, they will slowly stop burning as much fuel because the spark slowly gets lesser and lesser. On a cold day the fuel is harder to ignite with a small amount of spark.
Normal idle when its cold means that your cars idle is probably too high. If you lower the idle, the choke on a cold day will keep the idle a little higher until the motor warms and then it will kick back off. If the idle is too high, it will run very rich, smothering itself with fuel, and causing the idle to stay low. When the car warms, its creating better spark when its warm, and with the idle being too high its running at a fast idle.
The car wont start sometimes can be the cause of a few things. If the ground is bad on the fuel pump, it wont make a good connection sometimes for when you turn the key on, the fuel pump dont pump the fuel to the engine. Another one can be that your accessory switch can be loose going to the fuel pump. I think its your ground though. Good luck! Hope this helps.
Have a nice day. -Steve
