Can anyone recommend a decent compression tester that works with our trucks. I want to check mine and I just wanted to see if there was a tester out there that I can just pick up at autozone or somewhere like that. thanks

 

I race jetskis, yamaha GPR's to be specific. Measuring compression on a 2-stroke race engine is super critical. Having used every one out there, I recommend shelling out the money for a Snap On gauge. They're the most accurate and repeatable compression gauges known to man. They're about $225, but you can find them on Ebay for as little as $100.

 

I have used a Snap On gauge for a few years. It was in the 220.00 range also. Never had an issue with it.
