CYLINDER SQUISH BAND CLEARANCE CHECK

A proper squish clearance can give your motor 10% more power. Most aftermarket cylinder kits are not made to this close tolerance of 0.6-0.8mm proper piston clearance. We check the squish band clearance and usually have to close the gap from .18 -.13mm down to .8mm gap for proper squish band function to work properly.

Why not somehow place the solder on both sides simultaneously, to prevent erroneous readings from the slight rocking of the piston.. What I used to do was to place small balls of modeling clay in two or three points around it, and measure them. I found that on 80 to 125 CC motors I wanted .020 to .030 squish. But anytime I got smaller than .020, my top end power would sag, but low end and midrange was still good. A little more on bigger bores. I would adjust by cutting the head gasket surf.

@hillclimber62 That is an excellent point. I believe the book states to put the solder in a straight line with the Gungeon pin to avoid this. I had not thought about piston rocking before and I just learned something new. Thanks, RH DSD

you sound like Kevin Costner

@MCRmechanic KEVIN COSTNER IS COOL, BUT I AM COOLER...

squish cant give power to the engine!!!!

[DIOSpeedDemon]

@paul39man39yo NO, YOUR RIGHT!!! WE NEED MORE COWBELL!!!!!!

Could you please supress the music?

@kronfuss I have the fastest moped in my entire state. I took supreme olympic moped speed trials held in july of 2009. SO SUCK IT.

[hillclimber62]

I said top end power, but what I meant was top end RPM.. I would lose power at the top of the RPM when the squish got too tight. I have a theory why, but not too sure.

Great info!!! Thank you!!!

[paul39man39yo]

@DIOSpeedDemon haha.if i was speaking corectly english i was capable to explain you why. the squish only eliminate spontaneous ignition and yeah, can you have more power like you say in the video but not changing the geometry of the squish but reducing the volume of the ignition chamber. however nice guide to mesure the squish..
