i know its different on a 2 stroke. isn't there a formula you have to use if you use a standard compression tester? what should compression of a banshee be.

 

take out one of the spark plugs..put the compression tester in...hold throttle at WOT(wide open throttle)...kick her over and over really fast...but make sure you have the key turned off..not to sure on compression though..

 

Stock is 130 Lbs. in each cylinder. You should refresh your top-end if the compression is under 100 Lbs. , or if there is more than a 10 Lb. difference between the two cylinders. I bought my compression tester from Sears for like $24.
