What is Squish and How to Measure it!
Requested by you guys, here is how I measure squish and why it's important to do so. This is shown on a 421 Yamaha Banshee motor but the same techniques can be used on any 2 stroke motor. The micrometer in this video can be purchased at Autozone for 12.99.

Definitely much easier then taking the head off. An this is a great tutorial with explaining what your doing and actually doing it. Props to you bro💪
Exceptionally done! Very well explained and demonstrated. So happy you demonstrated the smart way vs the popping the head on and off method. This is very important on older 2 stroke engines due to the casting inconsistencies of the manufacturers (Suzuki was notorious for having squish band problems) causing engines to get bad raps when all that was needed was a decking job and different thickness gaskets.
I absolutely love your attention to detail and passion. You’re a true artist!
Please never stop making videos I always click on them right when you post them and you always teach me something
Like this way more then south Texas bolting on and off the head
Yes! Been waiting for this one 👍🏻
Very well explained. Thank you
Great video, taking the head off my Maico 450 and re cutting the chamber and making it Hemisphererical instead of the thick washer design (stock)
There is no better videos all your videos are the best right out the of gate keep on rocking dog
Small squishband will not create detonation! Its only there to get all the gases in to the combustionchamber, it is limited by the engine tolerances so piston not hit the head, to high compression ratio can cause detonations
Good work Mike !
Thanks man. Nice video. The artwork helped me better understand the squish band.
I’ve been told with my ktm 250xc that one of the motor Mods is to have .018-0.02 milled from the main surface of the head.
Which from your artwork I believe they are talking about the squish band area of the head. This was in essence to achieve more low end grunt.
Is this increasing compression in essence?
Another awesome video man. I love ur channel brah I can’t tell you how much $ it saved me and how much I kno now thanks again mike
Awesome tutorial 😁👌
Man i love you....... hahaha you realy helped me and thanks a lot for this smart tipp love your videos
Very well said:) I wonder if anybody has the right specs how to cut a squish band on a banshee head since I have a five axis CNC machine?
Great content
Awesome Mike《☆》Another use for solder, no iron required[-]☻[-]
Lots of opinions on squish band clearance but most experienced builders will tell you optimum is around .045 for durability and performance
Very well done sir. I've been scanning youtube for info on 2 stroke engines. Especially for someone like yourself who knows what he's doing. I knew little about them until recently. I am currently rebuilding a 1986 Yamaha 2 stroke golf cart engine. Getting to the point. what is the relationship between squish and compression ratio?
The engine specs say 5.7 : 1, Combustion chamber volume (with spark plug) 1.91 cu in. Compression chamber type Dome + Squish. Could you advise on how to get the compression ratio up to a more respectable level? Thanks, and cheers.
Have you tried rosin core solder instead of solid core? It's softer and easier to squish.
Can you make a video of what the right clearance is for maximum reliable power on pump and race gas
man i cant wait anymore to see this banshee running
Thank you.
How to calculate the right squish for the motor? Or is there a standard that you work from?
What is a good squish for a 4cvl 2stroke. I’m building my merc 4cyl2syroke. And I want to create the best squish. But I can’t find any reliable info. Im doin full rebuild full porting and balancing everything. One thing in serious question is the correct squish? I premix 50:1 with premium pump gas. I do run better fuel here an there but I want it set for pump gas as I run that more often.seems like you know your stuff so maybe you could help? Thank you. 1999 merc120hp 4cyl2stroke 1,800cc
What’s the squish for a stock cylinder with stock head?
hey Michael what are you using to edit your videos if you don't mind me asking and where did you learn to edit I really want to learn how to edit my videos and i like the way you edit yours please let me know if you can thank you.
I got a question. If your squish is incorrect on a single cylinder 2 stroke, what symptoms would occur? How much difference would it take to create an issue. My squish on my Tx300 was supposed to be .10mm and my measurement is .30. My KTM tech buddy said it's not enough to make a noticeable difference. Just don't want positive squish.
Clever idea. Love it. But now, how to adjust a difference? And more importantly, what would be an acceptable tolerance?
I thought I had in there that you can adjust the gap by switching out base gaskets, domes or machining. As far as tolerances; I did a fair amount of research and I got conflicting information from different sites. However the clearance I measured in my Banshee is in the safe zone as far as I know lol.
@@MichaelSabo Switching out the base gaskets with what?
Is it possible to completely build a banshee engine from scratch with aftermarket parts?
When you cut solder run a file on it so no sharp edges
What type of solder?
I’ve got a rm250 2 stroke it pings and detnates sort of revs it self. Happens right when I start it some people said it’s a air leak so I redone the hole motor with new seals and gaskets also replaced the cranks seals twice. I check the squish and it was 1.40 mm. Any idea what it could be. Thanks
Did you leak test to confirm?
Yes I found the problem had to much compression got a thicker gasket all fixed now
Do you need to do the squish, what is the purpose of it? I'm building mine and still confused
10,000 hell yeah
I wonder how many times the word squish was said... 🤔
182 times
Car person here. You cant make small changes with different head gaskets?
Is there "squish" on a 4 stroke too? Or is it just 2 strokes that you need to worry about?
Yes many four strokes have a squish band but by commonly is not measured or altered
👍👍👍👍

Primary job of the squish band is to cool the piston

Okay when you do your squish or squash you are supposed to lay your lead on both sides of the wrist pin at the same time and only squash it one time not two and three times. Every time you smash the led it will make the LED thinner. The squash on a gasoline motor it's supposed to be about .060 to .065 stock.
.050 is about as low as you want to go because you have a chance to take your rod bearing out.
I was just tell you the right way to do it.
I'm mixed on this. I have learned both way and also seen ways of using modeling clay. Each method has its pros and cons but personally this method works for me and it's the easiest in my opinion. As far as the gap range; depending in what the motor is used for or the type of fuel you're running; you'll get people arguing over answers. I'm not a pro this is just what I've learned from manuals, forums and other videos.

I don't know if you have a case splitter or a crank puller. I wish I could send you the link on eBay. It's a tusk case splitter ,crank puller for a $100.
Best 2 tools you can buy
Cr250 case splitter
Add 2 stroke to your title so it pops in more searches.

So the Chinese wrist pin didn't have nothing to do with the destination then 😉
Squish and combustion rate are 2 different things. A lot of guys dont know the difference.
