If you take it from the front or rear only in a bore that large then the piston can rock over to one side under pressure of the solder and may give you a wider value than it actually is, you might want to shove 2 bits of wire in facing opposite sides of the piston and measure both.
I actually measured it at the side, where the piston can’t rock significantly. When I have the engine back together I’ll try at the front, one time with just one piece of solder and a second time with two pieces (front and rear) of solder to see how much the difference is
Brad Hilaire - With an RK Tek head approximately 1mm. I measured 1.08mm and don’t plan on changing that when I rebuild the engine. I’ll use the same base gasket thickness as now...
Ok sweet I have taken 0.5mm from my stock head but added a small amount to the base and have come up with 1.34mm now has a bit more torque and by lifting the base it seams to have retained the top end maybe a tad more ??? Cheers Brado

Me encanta como explicas las cosas, tomas tu tiempo y procesos correctos y profesionales, nos ayudas mucho, te mereces un 11. Saludos desde España!!
Wow, so simple. I had no clue how to do this. I am going to check my 250 now. Thanks for the video!

AuMechanic I usually do that And remove the head to measure squish

Yep in line with the wrist pin is better, small end has minimal clearance.
Absolutely
great video
can you do a video on raising or lowering compression (who what where when why and how)?
I have KTM EXC 300 2017, I installed PK TEK. It says 13.4 what's the difference with 14.1. Squish 0.94 / 0.96 I'm sorry for my bad English
Hi chap
What is a good amount of squish for the ktm 250
Great videos by the way 👍👍🤘🤘
