    98 polaris sltx (red) compression

    The middle cylinder is showing 90 and the two outer cylinders (MAG and PTO?) are reading at 120. I'm not sure how to troubleshoot the loss. Are there any recommendations on proceeding?

    Some model years had an offset of compression. They had a lower CEN cyl compression VS. the other 2.

    Pretty sure Casey may know which years had this.

    Only the 97 1050 domestics had lower middle compression. And that was about 15psi lower.
