tarmacsti Posted January 20, 2012 Report Share Posted January 20, 2012 Hi guys, I would like to buy this Engine Compression Tester but would like to know if its the right thing to do a test on my banshee with. I know I can go to a dealer and they can do it for me but for the price I would rather just buy one. http://www.ebay.com/itm/5pcs-Gas-Engine-Compression-Tester-Testing-Gauge-Kit-Test-Cylinder-Tester-/120810352894?pt=Motors_Automotive_Tools&vxp=mtr&hash=item1c20dbb0fe Quote Link to comment Share on other sites More sharing options...
J.J. Posted January 20, 2012 Report Share Posted January 20, 2012 That should work. However: 1) You have to use the M14 adapter and this could interfere with the tank, meaning you have to remove the tank to do the test. 2) The adapter will likely increase the volume of the combustion chamber (when compared to the volume when the sparkplug is in place) Should still be good for baseline comparisons though. 3) Typically the range of compression in banshees will be between 100psi to 180psi, the graduations on the gauge in the pic are too large imo, making it difficult to see small variations. I bought a similar one from an autoparts shop and fitted a proper gauge. Was not expensive. Quote Link to comment Share on other sites More sharing options...

jbooker82 Posted January 20, 2012 Report Share Posted January 20, 2012 (edited) This is about as good as your going to get for around $50-60 bucks http://www.craftsman.com/shc/s/p_10155_12602_00947089000P?keyword=compression+tester&prdNo=1&blockNo=1&blockType=L1 The one you posted has an adaptor that threads on to the main hose. So the scrader valve is in the hose. So any volume you add (adaptor with open space) before the valve will be volume added to the combustion chamber. Now look at noss's table that shows what compression his different domes should have at a given elevation. It doesnt take very much volume to affect compression or your compression gauges reading.
