24 Sep 2008 14:32

Anyone know what is the acceptable compression for a 1978 KZ650 D1? I just tested mine and got the following numbers and I'm wondering if they look ok?

Dry:
#1 - 160
#2 - 160
#3 - 165
#4 - 170

Wet:
#1 - 170
#2 - 170
#3 - 170
#4 - 170

Thanks

Those are pretty good numbers. Your rings are good, that's for sure.
