draggins10 Posted April 18, 2013 Report Share Posted April 18, 2013 I did a compression test just for the heck of it, on my banshee I recently bought and got 93 psi on both cylinders. It runs perfect and pulls hard. Should I be concerned? Quote Link to comment Share on other sites More sharing options...
draggins10 Posted April 18, 2013 Author Report Share Posted April 18, 2013 I know 125 psi is the desired pressure, but this thing runs great Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted April 18, 2013 Report Share Posted April 18, 2013 Is your gauge accurate? I had a harbor freight one that read 60psi on everything Quote Link to comment Share on other sites More sharing options...
draggins10 Posted April 18, 2013 Author Report Share Posted April 18, 2013 Idk. I hope so, I just bought it from autozone. It's an Actron with 14mm adapter Quote Link to comment Share on other sites More sharing options...
Finch Posted April 18, 2013 Report Share Posted April 18, 2013 What's your elevation 125 is good on a stock motor at sea level if your up in the clouds it may be diff. Quote Link to comment Share on other sites More sharing options...
draggins10 Posted April 18, 2013 Author Report Share Posted April 18, 2013 1,270 ft. I also just read that you are supposed to hold the throttle open while kicking, which I didn't do Quote Link to comment Share on other sites More sharing options...
special06shee Posted April 18, 2013 Report Share Posted April 18, 2013 best bet is to go to sears and buy a decent compression tester. ive had several gauges that were bad or inconcistent. one of witch i bought brand new from an autoparts store. that paticular gauge read 30ish lbs low. ive had great luck with my craftsman tester. reads within 1-2lbs compared to my father's 2 snapon testers Quote Link to comment Share on other sites More sharing options...
dozer Posted April 18, 2013 Report Share Posted April 18, 2013 My Acton wasn't full length like a spark plug and would read lower than my craftsman on every engine. Quote Link to comment Share on other sites More sharing options...
hercalmighty Posted April 18, 2013 Report Share Posted April 18, 2013 The craftsman tester is well worth the money. Great piece that should last a long time Quote Link to comment Share on other sites More sharing options...
Dalton Posted April 18, 2013 Report Share Posted April 18, 2013 Buy a snap on motorcycle tester. Best $120 I ever spent . Had the same problem with the cheap testers and low readings. Quote Link to comment Share on other sites More sharing options...
SOUTHTHIRTY Posted April 18, 2013 Report Share Posted April 18, 2013 Do u test with the throttle full open of closed ? Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted April 18, 2013 Report Share Posted April 18, 2013 Install compression tester......hold throttle WIDE OPEN.....then kick.....and CONTINUE to kick until the needle on the gauge stops moving. That will be your compression. They say that more than 10% difference is a concern.....however i believe if its more than 5% difference...there something to possibly concerned about.

draggins10 Posted April 18, 2013 Author Report Share Posted April 18, 2013 Do u test with the throttle full open of closed ? Closed, i just realized now its supposed to be open throttle. Now I have to wait 2 weeks BC I left my banshee at my house upstate Quote Link to comment Share on other sites More sharing options...
