Can someone tell me what the compression should be on a1999 Vanguard 6x6 with a 16hp Vangaurd motor.thI can't find a number anywhere. I took a reading today and got 85psi on both cylinders and that seems low to me. Most of my atv's run about 120psi. If it is to low it will just be another thing to add to my long list of thiings needed to get fixed.
