Great video, nothing more frustrating then kicking the hell outta bike with no results. Gonna try it out today.

[@dirtniron]

cool Joseph, hope it helps

Again I say, you are amazing, you know how to explain. Guys this is a good teacher, I would never asleep at his lessons. Must to subscribe and must to like his videos, he is so great !

Thanks Robert! ;)

This dude speaks great English, and he helped me learn about bikes through one video!

[@dirtniron]

thanks a lot my friend!

[@nellports2108]

I just got a bike and I was kicking it silly trying to get it to start watched this and it started right up thank you!

[@youfoundwaldo77]

Thanks for the info. I'm new to riding and I always have a tough time starting the bike but from the explanation in your vid I got it started on the second kick.

[@dirtniron]

That's great Sophie, thanks for sharing!

[@GoldensniperGaming]

I always shake my head at the people who twist the throttle while trying to start their bike. On a carbed bike you just flood it and it gets harder. On FI you should never touch the gas while starting and if you have to then something is wrong. I love this channel keep making videos like this! Maybe you can make a video how to bleed brakes? Its funny because I ride a ktm 250sxf and all i have to do is click a button haha

[@dirtniron]

Thanks man, I will put it on the list.

[@blazbencic5453]

[@Tocco609]

my dad always said, if you bike is jetted right you should never need throttle to start em

[@vaneater2734]

Dirt N Iron It's a 2009 kx85 that I got for 1000 with aftermarket steering stabilizer and and linkage and it just had the top end rebuilt and came with the old piston which had no ridges in it or anything basically perfect spare top end and very very powerful powerband. I haven't ridden it anywhere near it's full potential or top speed. Very scary powerband when starting out but I'm getting used to. Awesome bike and fits me great. You're right, you really can start riding with 1000. Very fun and very fast.

[@dirtniron]

+Vaneater congrats man, sounds great!

[@blakecooper9777]

Helped me start my newer 250 four stroke efi. I changed the plug, spark plug, air and oil filter, and gas in the tank. Still wouldn’t turn over. After using the throttle wide open technique it started! I guess it was so bad fuel in the lines. Either way, huge help!

[@jakobfolmar6604]

Thanks so much for this. I rode 2 strokes all through the mid 90's and 20 years later now just bought this exact same bike. First off I was looking how to turn the gas on lololol, next not knowing what the choke nob is then once its hot and I'm stalling constantly cause I'm riding with my 12 year old on his first two stroke wondering how the fuck this bike kicks over cold as can be and kicking to death to start it hot. I'm 36 and feel like I'm 70. So much difference in these new 4 strokes I never owned an older one so this vid answered all my questions thanks so so much!

[@dirtniron]

thanks Eddie!

[@thcpsilocybin9978]

@@dirtniron Do i need to twist the throttle at every environment conditions or only in cold if you think the bike aint gonna start ?

[@LukeBrinkerhoff]

I’ve shown so many people that just kick and kick and kick their bike like it’s a 2 stroke. When you hear a whoosh sound that’s your intake valve sucking and closing, there a little notch or click in the stroke just past that sound. That’s the piston beginning it’s compression stroke. This is where you bring it to the top and kick all the way through don’t stop, don’t have to kick hard usually just all the way. Bike started 95% of the time this way(until valves need adjusted) now if you have a manual decompression lever it won’t work. Worked on a 2006 yz450, 2013 yz250f, 2015 yz250f, 2014 rmz450, 2017 crf250 that I can think of. So yeah you don’t bring it to TDC like a 2 stroke. You have to ram the piston into the compression stroke so it will fire.

[@dirtniron]

thanks for sharing

[@LukeBrinkerhoff]

Dirt N Iron no probs. A lot of guys I race against would tell me “I can’t believe how fast you can start your bike in gear” I was determined to learn how to start it easily.

[@harryford82]

Thanks for this video, my bike wouldn’t start after being sat and after 3 full twists of the throttle it fired straight up

[@brandonbeaver2468]

Just bought a 2011 yz450f. My first 4 stroke race bike. Is it normal for me not to be able to kick start it in gear with the clutch engaged? Never had issues on any other bike.. also, its nearly impossible to find neutral while the bike is running. Any advice!? You are the man and best channel on YT

cool man, congrats! hope its better now after we talked ;)

[@TBuilds888]

Ikr!

[@beezykaine773]

Same with me when the bike started its hard to find neutral while it’s running on my newer bike & when it get hot it’s harder to kick over

If you open throttle when kicking a fuel injected it can get much harder to start

when you try full throttle and kickstart, don't forget to push and hold killswitch button, or kickback may happen and its more dangerous on fullthrottle.

If engine floods i generally turn off the key and keep kicking so that fuel gets pushed out via exhaust valves.

Great video man! I have a question, I have a carby 2009 ktm 250 exc-f 4 stroke, can I lay it on its side on a track or will it flood the carb? I ask because sometimes when you fall over and fuel spills out it is harder to start. Thanks

[@dirtniron]

the fuel will come out from the overflow.. you should still be able to start it just fine.. i would not recommend to lay it down on the side willingly .. sometimes you cant avoid it when you crash..

[@scottkalmus1736]

I recently bought a 2014 YZ250F (fuel injection) in great condition, only about 12 hours on it. When I visited the original owner I asked him to have the bike cold so I can see how long/hard it takes to start it. He was able to turn it over in 3 kicks. My previous bike had an electric start so I never had to experience kicking it over. The compression seems very good, but I have a hard time kicking it over. Is there anything else I need to look over that would make turning it over harder than it should? Great videos by the way.

[@dirtniron]

some bikes have decompression lever of the handlebars, I dont think your bike has it. Perhaps checking valve clearance would be good idea. how many kicks does it take to start ?

[@lorcanzhang2345]

Do you's think a Honda 150 cc is too big for me I'm 11 years old going 12 but in 5 foot 3

[@dirtniron]

oil change including the filter, new oiled air filter, correct air pressure, wash it nice to inspect any possible problems, maybe check the valves if the bike runs rough or doesnt want to start.. and have fun

Hey man I saw your live around Temecula any good riding trails I’m from Elsinore.

[@CarlosRamirez-pi7wo]

Do you hold the hot start when kicking it cold ?

[@yukonjon5964]

no. only when hot.

[@natebiegalle3962]

Purpose of hot start function on fuel injected bike?

[@yukonjon5964]

when an engine is hot it needs a leaner mixture. at start up, the efi system has not had time to sense and decide its condition, if hot or cold etc. so you decide for it. when cold you pull the choke type button so it starts easier, when hot you pull the hot start lever which leans it out a bit and keeps the richer default starting setting of the efi from flooding it. when really hot, it will start better with the hot start lever held.

[@yehyarf9949]

Hi Thanks for the helpful videos. I really like them. My kick is stuck and it is very difficult to move it down,what could be the problem?? Thanks

[@dirtniron]

I am not sure, hope your engine is ok. does the bike run?

[@yehyarf9949]

Thanks for the reply, The bike runs well,I can start it by kicking but it's jammed at the beginning,so I need to push really hard to release it and then I can kick it easily.

[@mattb4886]

[@angelcerna5577]

Have a 2006 crf250r haven’t used it in a couple months, tried to turn it on and did not want to turn on over several kicks. Then on one kick I heard a pop on the exhaust. Need a New Spark plug??? Or what might the problem be

[@dirtniron]

I bet it's a carburetor. Old has, your jets got dirty. I would take the carbureror off and clean it. If you don't want to do that then at least take out pilot jet and clean it.

[@davidbaxter8511]

Another great video mate, question though I've a 2007 rmz450 the previous owner disconnected the manual decompression lever saying you don't need it, i really struggle to start the bike, have you any advice? Thanks

[@dirtniron]

what kind of struggle? is it hard to kick it over or it doesn't want to start ? if it doesnt want to start then check the valves clearance and then carburetor.

[@davidbaxter8511]

Dirt N Iron it just doesn't want to start, it kicks fine and will start eventually, I've only been used to 2 strokes before this bike so wasn't sure i was doing it properly, I'll five your suggestion a go and hopefully will make a difference

[@davidbaxter8511]

Dirt N Iron hi pal after a bit of investigation it turned out to be the manual decompression was stuck on, I disconnected it and cleaned it all, started fine after that 👍👍

Re connect the decomposition lever

[@Thrillowatt]

hey could you do a vid on explaining powerband? thanks!

[@jakobfolmar6604]

montgomery mchargue lol

[@yukonjon5964]

powerband only means the part of the RPM range that any given engine makes its most usable power. it has nothing to do with the actual engine. mainly only relevant when looking at dyno charts. it's mainly a 2 stroke thing. the fat looking exhaust pipe is designed to make use of sonic sound waves that bounce back to the cylinder at just the right time to keep the air/fuel charge from escaping out into the pipe unburnt. the engine runs best and makes more power when these sonic waves are doing their job perfectly. at that point in the RPM range the engine is "in its powerband".

[@jamesagostino3695]

Thanks for the video dude ! Great stuff. I forgot that you shouldn’t use throttle on a FI bike when starting ( my manual said as well ) . I have done it a few times as I’m use to a two stroke. Could I have done damage ? Is it more of a “don’t do regularly thing”? Thanks in advance !

[@dirtniron]

no worries James, you dont damage anything like that. Some fuel injected bikes starts better if you crank open the throttle just a hair.

[@jamesagostino3695]

Dirt N Iron thanks man ! So I guess the manufacturers say that as a precautionary measure to cover their butt!?

[@yourmamalikesmacncheese]

Glad I came across this video. I have a 2008 RMZ450 which I bought used. It is a real bitch to start. Now I have some other techniques.

Do you know what might be wrong with my bike it’s a 2016 kx450f and it starts only with throttle after I changed the oil. And it sounds a lot quieter than it used to be

That sounds little off. Oil change should not change anything. Did you do everything right? Filter is in correct direction, good amount of oil?
