All should be over 135psi as a general rule with no more than a 10% variation.

Hello Willfen57,
I checked the compression of my engine last weekend and was looking for the figures to measure against hence the 135psi that was supplied dingg1 as I could not find on google. My figures came in at around 130psi but not sure due to the kit I used but not far off.

I will make a note of your engine for future requirements

Thanks

If they are all around the 130 all is well 👍
