Compression on engin

Post by Draco »

Can someone clarify, I checked my compression as well as Freddys sx and both of us measure between 700 and 750 kpa per piston.

The manual says it must be 980 kpa at least, I redid my engin in feb and Freddys engin doesn't give any problems so, why only 700-750 kpa on both?

you did keep the accelerator wide open like the manual says didnt you? not doing so would also result in low readings.

Jay_boy, it is a brand new meter I "invested" in at Midas so I don't see why it would not work properly. If anybody can proove my meter wrong please do, so I can shuv the "investment" back into Midasas a-hole.

I still don't think the meter is problamatic.

Worst compression wins - so that the winner can use the money to fix it :-)
