on a 02 zrcc 600 efi i replaced one side,, when i checked compression one side was 114 ( old side ) and new side is 130 with a new piston and sleeve. the sled has aprox 3k mi and the crank case seems solid..

is 15 lbs acceptable or do i need to do both sides ?

any help is appreciated thanks...

you should probably do both sides, to be safe, it shouldnt be more then 10psi difference
