I did a compression check and ended up with 200 psi on #1, and 205 on the other three cylinders. This seems to me to be high. I have 400km on a rebuilt motor with 8.5:1 pistons, an HKS 1.6mm mhg, and a decked head and block. My build calculations put the compression ratio near the stock 8.8:1, but I'm beginning to doubt this now.
So, is this compression too high? Will it drop after I log some more miles? What do other people have for compression?
