Hello TH-camrs today ill be showing you guys how to replace a spark plug on a 2 stroke dirt bike. The procedure is pretty much the same with all bikes, 2 stroke and 4. If you have a 2 stroke and you are not sure of when the last time it had a spark plug change this may be the reason your bike is not starting. You always wanna keep a fresh spark plug in your 2 stroke. You should change them about every 4 rides on a two stroke. They are cheap and will keep your bike running great if changed appropriately!

She sounds good
Thanks bro, I tried to keep her prime. Had to sell her unfortunately!
Is it the same with a kx250?
thanks !!
very helpful
You could have left the tank on we change them in the field if needed
Dieter Gick Oh I know man Ive had to change my fair share of plugs while deep in the trails 😂 but I just took the tank off for the new guys so it'd be easier to see exactly what I was doing
This guy is clearly not clued up at all
That shock is clapped
Pliers to tighten a plug?? Get a wrench man!! 🤦🏼♂️
There actually channel locks
way too tight in my humble opinion
Is it a irridium?
Thanks for watching guys, leave whatever questions you guys might have here 🤙🏾
Would you know why my bike lost compression after changing the spark plug?
Make sure the plug is tight
The spark plug is too loose
I can’t get my cap off my 2020 yz85, it’ just won’t budge. Do you know way to take it off?
Yeah you probably just need to wiggle it loose with some pliers or channel locks. Its made of rubber so dont be too rough on it just wiggle it enough to break it loose
My 2018 yz85 is doing the same thing🤣🤣🤣
yeah i learned the hard way with a newer GMC half ton, you need a special tool just to get the G.D. caps off!
Don’t tighten your spark plug just make sure it’s snug don’t gotta turn it 100 times smg
Absolutely right 🤟🏾
What do you have your air screw set on and what fuel ratio do you use
subtoxic turn it until it dies and then keep increasing it until it idles low but with out dieing
The manual suggest 2.5 turns out. jf ur not sure what I mean just turn your idle screw all the way in, not tight but just as many turns as you can get out of it and the turn it 2.5 turns to the left. And like my buddy said below just play around with it thats just a good starting point
subtoxic In my 125s once their broken in I run them 40:1 but when they have fresh rebuilds 32:1 like the manual suggest. On my 250 2 strokes 32:1 premium pump gas. would like to find a little higher octane without converting to VP.
Really bro? Pliers?
i changed the spark plug correctly now what should i check ??
If your bike still isnt starting with a new spark pug you may have a dirty carb or a bigger issue. a motor needs 3 components to run: Spark (electrical system & plug), Air (airbox, carb, reeds), and Fuel. If you are sure that the bike does run and it is just hard to start then you may need to clean your Main Jet and Pilot jet in your Carburetor. You can find plenty of tutorials on TH-cam on how to do it. I might even do my own once I get my current projects running.
@@bamtracing2624 thanks a lot ! it’s was the pilot jet.
Did you have to set a gap?
Yes
Man I wish I was that tall
I got my knees done bro 😂
Where can i get from
Hulk Smashed1982 your local motorcycle shop or ebay
how tall are you
6'5 brother
Nice n white and shiny. Lol.
Lord help us.
yes he need learn to diference thing
I have a problem which i really need to fix.
The bike that i have in my profile picture is the bike that i own and have the problem on.
It is a KTM 85 2-Stroke.
The problem is that before i could easily start it with around 2-3 kicks maximum.
Now, on this apperant day, i start the bike, good as normal, and it dies on me.
I think weird, let me check the gas, the gas is ok but for good measure let me fill it up.
I fill the bike up and try to start it again.
It wont start, i clean out the brand new spark plug i got and it still wont start. I put the choke up and it has some life on the first kick.
But then it gives up.
Please help, i would apprechiate it dearly 😷
I would say its time for a carb disassembly and through cleaning, clean all of your jets out with a small wire bristle brush or compressed air. if the bike has low compression and/or seems like it has lost power and isnt as snappy and quick it could be time for a top end rebuild which isnt too complicated. You could do it yourself by watching some youtube videos as you do it. Great thing about two strokes is they are fairly simple to work on. If you end up doing the rebuild yourself make sure to check down in the crank for metal shavings and for play in the crank rod when you take the cylinder off. Hope this helps bud
Raised Suspension ⬆️⬆️⬆️⬆️
Raised Suspension Also make sure to check of your air filter is clean. If not buy a new one. Pro filter makes $10 pre oiled filters for most bikes. If your air filter is too dirty your bike wont run because it cant breathe. Keep rippin and wrenchin buddy 🤙🏾
Thanks bro, btw every time i ride i clean out the air filter. That actually wasnt the problem, i needed to clean out my carburator, you were right. Thanks, btw i need a new spark plug too :P
Raised Suspension same thing with my kx 100
I Kick the bike but spark coming into carborats not starting
What happens when you kick it over
@@bamtracing2624 not starting
If it has spark its gotta be the carb is dirty or it has low compression
I just bought one for 300$ yesterday
Meme Rider i hope you mean dirtbike. And not spark plug
Shed MX LOL ya, never a 300$ spark plug. I got a yz125 for 300$
Meme Rider Thats a great deal man
Lol if I it ran right it'd be. O traded it with my kdx for a CR250
Meme Rider What was wrong with it? And what year CR did you get? That white bike in the background (not the red 90' CR125) was my 96 CR250 and she was a beast. Got her for $200 as a roller with a trashed motor and rebuilt her all for about $500, sold her for $1300 I really miss her lol. Scary fast bike one of my favorite bikes ive ever owned
Did she not start before?
she started but it took many kicks and also she wasnt running prime she was running a little rough and didnt want to idle. I either figured it was a carb issue or the plug
Bamt Racing yeah i had the same problem with my kx125 but it didnt start thought it might be clogged carb was gonna clean it that afternoon but wanted to try a new spark plug and started 1st kick
@@enokylurjonasson6594 if she doesnt idle properly id still check the car but yeah always check your plug
@@enokylurjonasson6594 my dirtbike don’t start either I finally have the right spark plugs coming in
My bike wont start we changed plug all Electronic to. Im fucking done with suzuki
It could be your carb or your air filter. Always make sure you have a clean air filter. Google best jetting for whatever bike you have and keep your location in mind as well as if you have an aftermarket exhaust which would mean that you would have to find out the best jetting setup with your exhaust setup. I would still run a circuit test on the electrical to make sure there are no shortages. Also want to make sure the bike has good compression. If it has low compression and wont start its definitely long over due for a rebuild. if your cylinder is fine to use throw a piston in there and some new gaskets. Post a video and I may be able to help you.
@@bamtracing2624 I dont need to clean calbulator* or my airfilter to get a spark in The plug
U sure it's br8eg I get br8es
either is fine they’re pretty much the same plug
