Hello UpAllNight91, ive been watching your vids on the YZ450F and using your vids on my own 2017 YZ450F, i have a few startup issues when kickstarting it most times it takes me like 5-10 kicks to get her going and even when i turn it off and try to kick start it again straight after it take a few kicks when warm, any ideas how i can fix this issue ? cheers.

[@UpAllNight91]

Hello . Do you know when was the last top end? Sometimes a tired piston and rings can take a few more kicks than normal to fire up. Also sometime a old worn spark plug can cause hard starting

[@Vosccy]

Bike turns on then shuts of two seconds after its running could use your opinion on what you think it is the time I did get it to start I made it bark then it turned off again. When I kick it it starts for a second or two then turns off what you think the issue could be?

[@UpAllNight91]

Hello. I would check the fuel pump. Make sure its making good pressure and holds the pressure well. Next thing I would do is back flush the injector. Sounds like it's starving for fuel. I had a bike here that did the same thing and it was a weak pump.

[@thesporter12miller73]

Where did you buy that fully set up fuel pump cause I have a 2015 yz250f that needs a new pump and I don’t want to just rebuild it

[@UpAllNight91]

Hello. If it happens after everything gets hot it could be the fuel pump but also could be the stator. Both quantum and all balls are good kits, either one will work well. If that doesnt fix it up maybe take a jab at the stator.

[@Queloqueloco]

My outlet of the fuel pump(where i connect my fuel hose) leaks fuel when i take the fuel hose off , i heard it takes pressure out of your system and could be the cause to my fuel injector not spraying when i kick it from lack of pressure, any idea what i should replace or do apparently its not suppost to leak when u take the fuel line off of the fuel pump outlet

[@UpAllNight91]

Hello. If the outlet of the pump keeps dripping fuel when disconnected, every time I have seen that the pump was not good. I would take the pump apart and check all the seals, and fuel pressure regulator and stuff. I have seen the yz fuel regulator go out more often then others. Which a good pump it should build enough pressure in the fuel line after being reconnected to start up within 5 to 7 good kicks

Hi bro I have a question, my yzf 250 losing power when Im on full throttle(like starts bogging a little) , many people told me that the fuel pump is problem. what do you think about it? thanks 🙏

[@UpAllNight91]

Hello. It could be the fuel pump but I have also see spark plugs cause the same issue. I have also seen throttle position sensors do the same. I would first start by changing the plug, and check the throttle position sensor if you have the hand hand tuner or if yours is a 2019 or newer you can use your phone. If all that checks out good then I would dig into the fuel pump. Good chance its just a plug, I've seen so many shops over look that

Great video. I have a 2017 yz250f in otherwise great shape, (no e-start, about 60hrs on it) but it always takes two or three kicks to start. Any ideas what I should check?

[@UpAllNight91]

A kick start bike can often take 2 to 3 kicks. My 2015 yz450 is in great shape and she's like that. Sometimes I can get lucky with a single kick start and I often feel it on the kicker knowing its gonna be a good one. But 2 to 3 is kinda normal. Remember no battery, so your single kick is spinning at stator which is making power, power is needed to turn on the ECU and fuel pump needs power and needs to prime up fuel pressure. Sometimes all that doesn't get there in time on the first kick

[@smauller623]

@UpAllNight91 I have an issue on my 21 yz250fx….bike fell over on stand at track blew 15a fuse replaced and bike started again but after riding noticed the fuel pump wouldn’t shut off. Any insight before I buy relays>pump>ecu? I checked connections and grounds all seem normal.

[@Rikidybones]

Question, I have a bike that has been sitting for years. Changed the spark plug (has spark), replaced the fuel pump (was corroded), and did an oil change. I put gas down the cylinder as it wouldn't start and after a lot of kicks I got it to run for a brief second before it turned off. What else should I look for?

[@UpAllNight91]

Hello. If she can bark off for a second when you put gas in the cylinder than is safe to say the motor is good. I would check that the fuel pump is producing fuel pressure with 12 volts ran to it. Next thing would be injector. In my experience when a bike sits so long that it trashes the fuel pump it often takes out the injector with it. I have had luck a few times by back flushing the injector but in most cases it just needs a new one. If you get a new one I highly suggest a OEM one from yamaha

They should not leak when the pump is not running. When it leaks that usually tells me something is not right with the pump. Most likely a o ring out of place or a leak somewhere. It most likely will leak or bleed the pressure off. If you do a pressure test it probably will fail. I was disassemble the pump and double check everything

Hey mate is it possible for the pumps to go bad after sitting for a long time? Let my 2014 yz450f sit for 2 years and now won’t even burp after 100 kicks, I drained fuel, cleaned injector, etc, it’s got a brand new top end also so I’m guessing fuel pump is culprit

[@UpAllNight91]

For sure. Very common when they been sitting for some time. I usually just check the pump like I did in the video with a battery and pressure gauge. You will most likely find it bad. When they sit that log not only the pump motor can go bad but also the fuel pressure regulator thats on the pump housing. Also sometimes the injector can get gummed up from sitting as well. But I start with the pump and keep my fingers crossed that the injector is ok. 80% of the time it is.

[@Rkmmm751]

If the fuel pump is the issue, would it still run ok after getting it started even if it takes like 10 kicks to get it started? I wonder this because of how fast it would lose pressure in the beginning of the video with the bad pump as opposed to the end of the video with the good pump. I have a 2014 yz250f and usually had trouble getting it started, but once it was on it would run fine and it was also pretty easy to start when it was warm. Just recently however it started failing me even while running, it would start to bog and lose power and would occasionally pop as well. My buddies and I think it might be bad gas or dirty connectors or dirty injector something like that. I haven’t taken it apart yet but am thinking about doing it soon so any advice is greatly appreciated. Also thanks for the video man, very thorough and detailed!

[@UpAllNight91]

Thanks man! Totally sounds like a fuel pump thats failing. I have a bike here right now with the same issues. First was hard to start cold. Then started bogging and popping and getting worse and worse. Checking the pump and it drops pressure fast and with power ran to it, it varies pressure consistently, not holding steady. I'm replacing the pumps motor and also the fuel pressure regulator. That should fix her up. If you don't buy a oem pump assembly then I do suggest a fuel pressure regulator and a fuel pump motor rebuild like like all balls or quantum

[@UpAllNight91]

Could be a fuel pump or a stator. Both are easy to check. Get her hot till she shuts off. Hook a pressure gauge to the fuel pump and kick to check the pump for pressure. While having gthe tank up pull the spark plug and ground it on the frame, kick and check for good spark.

Washed my bike yesterday nothing new or out of the ordinary. No pressure washer or anything I never blast water into where it shouldn’t go. Was in washing it I heard the buzzing from the fuel pump randomly kick on for a second. Nowhere was I near the start button. Started it after I washed it and took a while but finally turned over. Let it sit for a couple hours and now nothing. Fuel pump won’t even turn on and make that buzzing noise which leads me to believe it’s fuel pump. Turns over fine but no spark either. You think it’s fuel pump? Watched your other video and saw you only replaced the injector. Any thoughts?

[@UpAllNight91]

Right off the top of my head, I'm guessing your PCM (some call the CDI) went bad. No spark and no fuel pump action but was acting funny turning stuff on on its own before going dead. I'm guessing PCM. I have seen these PCM's do strange things when they go bad. Example on one bike it would never shut the fuel pump off after shutting the bike off, it was a bad PCM. But of course before buying a new PCM I would check as much as you can. First check the fuse on the starter solenoid/relay. Maybe try diconnecting the PCM and checking terminal is clean then reconnect. If you know someone with a bike like your ask to try their PCM on your bike. Its advised to always check the whole harness before just buying a new PCM but that can be so time consuming.
