I can agree with a good bit of what you said but here’s an important point. I didn’t hear you mention (let alone stress) how to tell if their bike is too lean. When you tell someone not smoking is OK, in fact that’s how it should be, that sets them up for possible detonation and blowing a motor. It’s a very fine balance and you could have a lot newer guys see this, be running way too lean, or make changes that make their bike to lean, think they are spot on with your advice and BAM blown motor. You should really stress how to tell if they have too lean of a set up.

This may be a silly question; but does the same apply to 2 stroke car engines like the Soviet Trabant? Many restored cars in good running order appear to run a lot more cleanly than those that are poorly maintained. I have seen one at a car rally a few years ago and it wasn’t as bad as is made out do by no means modern. Thanks & great video!
All my 2 strokes run clear when warm, yard tools, bikes ect. I started to wonder why one day but I guessed at the time it was my bad mix ratio or oil type before I officially knew that it was a good thing instead!

All 2strokes smoke. The amount of oil mixed with the gas will determine the amount of smoke that comes out the exhaust. Two Strokes smoke because they burn oil that goes through the cylinder with the gas it’s like saying a fire won’t smoke.
I tried to explain this to my buddy at work. My KTM only smokes a little when it first starts and after it warms up not at all. You got yourself a new subscriber fine sir!
My bike doesn’t really smoke it will sometimes when I get on the pipe but then clears up but I do get a bit of sludge is that alright it’s not an extreme amount it’s just a little on the tip of the silencer
I have a polaris trailblazer. It’s air cooled and I am trying to figure out what temperature the cylinder should be. It gets to about 260F when driving hard.

Dude awesome video! What oil do you run I had a hard time catching that in the video, I run 927 and I think that’s why my bike smokes so much give me a couple more pointers love it
Your hillarious 2 strokes smoke or there gonna blow up billy.bolt and Graham Jarvis run 100 too 1 only reason they don’t look like they smoke on film.but they do keep smoking that good shit!!!
Wow. Thank you for the video. I’m new to 2 strokes; bought an 06 CR125 last year and I’ve been having nothing but issues. Blue moked like crazy; fouled plugs every 20 minutes; didn’t know heck all about jetting or playing with carbs. And she bogged. Then my brother put it in a pond and it bogged more; plus a nasty rattle.
New piston later and had a professional Jett it is it works. . .better. I think now it’s mostly my skill and gearing holding me back now. . .
Again, thank you for the video; that was a wonderfully informative video for us "2 smoke" noobs.

my scooter is a 2 stroke, and since I, oh Idk, know how to tune my carb, mine only smokes like a steam engine for the first 10 seconds of standing on the throttle after starting if it has been turned off for 20 mins or more. Granted I think I need to minutely adjust my low speed screw by like 1 degree, to just remove the burble when instantly flooring it that I did not have last year, before I changed the electric choke and spark plug and cleaned the carb and changed the air filter, that I have not oiled, because fuck it.
Theres certain oils to mix that don’t really smoke but if it’s not smoking from the ratio then your running it lean better for trail riding and putting around so you don’t foul plugs but if your running it hard run it rich when the bike gets hot it’ll need a bit more oil than just idling and warming up mixin gas and hauling ass
I run that redline race oil in my 2021 gasgas mc 125 it smoke when i first crank it after sitting for a week then it clears up and run like a beast there is no spooge in the muffler and that is on the stock jetting.
My bike just barely smokes once it’s warmed up and cleared out, I run 40:1 and do fast paced enduro racing and the end of my silencer is has a light film inside but none running down the silencer and no ring around the end
Excellent video. Think about air cooled 2 stroke lawn equipment. I have an 8 yo weedeater and I live in Fl. It probably has 40hrs on it. Granted it’s mixed at 50:1 but guess what? No smoke! Very helpful. ’84 KDX200 mixed at 40:1. This video helped me get the most out of it via rejet. This was eye opening for me. Thank you.
A properly tuned 2 stroke doesn’t smoke!
2:12 your not supposed to stick your thingy in there
I have a 96 kx125 it don’t smoke just to started smoke a little bit I use Lucas 2 stroke less Ash and no smoke I mix 40-1 all the time
Here is the 2020 Glen Helen nationals…no smoke 2 stroke race. https://youtu.be/2VQceYEZOX0

Yes but Graham Jarvis rides a TPI
Who doesn’t like the smoke😂
All my 2 strokes run clear when warm, yard tools, bikes ect. I started to wonder why one day but I guessed at the time it was my bad mix ratio or oil type before I officially knew that it was a good thing instead!
Any idea why my 4 stroke smokes help please I’m new to riding bikes
The more it burns unclean the worse it’ll run? Almost sounds like when people tune a diesel to roll coal lol
All 2strokes smoke. The amount of oil mixed with the gas will determine the amount of smoke that comes out the exhaust. Two Strokes smoke because they burn oil that goes through the cylinder with the gas it’s like saying a fire won’t smoke.
The day my two stroke stops smoking I will
I have spooge and smoke coming for my 2T scooter it’s a 70cc big bore kit and I have a 78 jet in the carb I’m guessing this is too big
I tried to explain this to my buddy at work. My KTM only smokes a little when it first starts and after it warms up not at all. You got yourself a new subscriber fine sir!
My 2 stroke smokes it is a 2 stroke dumb dumb
Makes sense that my RM was running rich, I added more oil to be safe, for the first start up. I’ll try doing a higher mix ratio, maybe 35:1?
Mine does it pretty much has lung cancer
Food for thought…. would this mean the same for old school machines as I have a aircooled IT465.
My bike doesn’t really smoke it will sometimes when I get on the pipe but then clears up but I do get a bit of sludge is that alright it’s not an extreme amount it’s just a little on the tip of the silencer

I 100% agree.
My bike smokes a lot when starting in the cold, but when warm and riding it doesn’t
Now Wankel engines, that’s another story.
How do I tune it?
Never mentioned ratio.
That part when he rubbed the exhaust had me thinking… I thought I was the only one obsessed with 2 strokes and everything about them.😆
Dude awesome video! What oil do you run I had a hard time catching that in the video, I run 927 and I think that’s why my bike smokes so much give me a couple more pointers love it
My snowblowers don’t smoke when warmed up. They smoke a little bit when cold start. proper mix has alot to do with it too.
Your hillarious 2 strokes smoke or there gonna blow up billy.bolt and Graham Jarvis run 100 too 1 only reason they don’t look like they smoke on film.but they do keep smoking that good shit!!!
It’s because he’s running a really Lean ratio 32:1 is the way to go
I love smoke, at least I know its getting oil
Mine doesn’t too cuz i don’t over oil my 2 stroke

Dirt bike riding is like this there’s two types of guys 4 joker or smoker 🤣🤣🤣🤣
mine smokes a bit when I’m sitting idling for a while, or when the choke is on
The exaust was disconected at the front
Older 250cc bikes can smoke
Idk why my two stroke moped smokes
My bike is 41 years old, of it smokes, good, means it has oil

all 2 stroke bike smoke like hell so i sell my dirt bike and i buy 4 stroke and im happy now !

It depende on the 2stroke oil…if its mineral oil it will smoke..if its synthetic it will not smoke alot..
They all smoke untill they warm up
I run that redline race oil in my 2021 gasgas mc 125 it smoke when i first crank it after sitting for a week then it clears up and run like a beast there is no spooge in the muffler and that is on the stock jetting.

What a numpty lol
much appreciation for this informative video!
I saw that my YZ125 today was running right then. On the gas barely any smoke except for when you brapped it or free reved it
