Compression testing question

[cline]

Prior to the beginning of 2012 I was that guy getting raped by all the quad shops that took all my money and returned me a pile of shit which is why I don't know a lot. I have recently been asking a lot of questions but trust me I have read way more in here than I have opened my mouth so I hope that I am not annoying you knowledgeable veteran guys. I read every day in here as well as use the search bar but some things I just can't seem to find the definitive answer to. Ok so I hear guys in here all the time talking about doing compression tests and have gathered that it measures psi in each cylinder but I have never seen how the compression test is accomplished or what tools are need to do one. Any descriptive outlines, tutorials, videos, links ect. would really be appreciated. Thanks for the help

Would suggest getting a quality gauge. Make sure the plug hole adapter is same length as spark plug, if it isn't you will read low, about 5 or more lbs.

The you tube one about 4 down is good.

Knowledge isn't worth a shit if it isn't passed on.

If you have an Autozone around you, they will rent a decent compression tester for 42.00. When you return the Compression tester they refund that 42 bucks back to you. Make sure that you are WOT when you do a compression test or it will not come out correctly.

 

If you need any help, there are quite a few guys that can point you in the right direction. The banshee is an extremely simple ATV with its limited computer and wiring harness. With a basic set of tools you can accomplish most of the maintenance on the bike. With a few more special tools, 32mm socket, 27 mm socket, flywheel puller, clutch basket holding tool, the rest of the jobs can be done with little effort. If you do not have a service manual you can DL the one in my sig for free.

 

In regards to compression testing, the closer you get to 100 PSI the closer you need a rebuild and if the cylinders are ever more than 5 psi it can be bad. Make sure the test is done with an engine at operating temp.
