compression ques

[banshee2]

ok so i wanna check my compression check but need some help on how to do it right like how many kicks to get the right reading? thanks

Usually i do it cold first, hold it WOT and kick it untill the needle stops moving, usually 20-30 kicks for me then i warm it up to full temp and do it again.

hey will it give the correct reading with the throtlle wide open?and how close should the psi be with each cylinder?

yeah it wont give the right if they are closed, and IDK about the compression i have one that is like 10-15 off and its fine.
