Performance Tool W80579 Flex Drive Compression Tester Kit - Professional Automotive Engine Diagnostic Tool for Cars, Trucks & Motorcycles (Use for Engine Performance Testing, Maintenance & Troubleshooting)

I bought this to use on my Harbor freight leak down tester because it did not come with anything that would work with my boat these attached to it perfectly and I was able to perform a leak town test on my boatI would have given these 5 stars if it weren't for the fact that a couple of the adapters do not have wrenching flats. It makes them hard to remove.Los use para el reloj de verificar la compresión de los Pistones y como todo vehículo es diferente tube q comprarlos...had the fitting for ford 5.4 engineI like it and although it’s the only one I have been able to find while shopping ,I recommend it.✅Gives my snap on compression tester the capability of testing small engines on like a 1972 Honda CL100SL. Highly Recommend if you need to test small engines compression ratios, and need the adapters to make it a happen.ExcelenteTwo of the adapters in the package of four adapters do not have a hex shape that will accept a socket. So, the problem with this is if they come undone way down inside of a sparkplug recess it will be a task to get them back out without damaging them.Needed a 10 mm adapter and nobody locally had one. Prime had it to me faster than local suppliers.A little priceyAppear to good qualitySomething that all compression testers should come withI thought it worked great on my motorcycle, checked the compression all good.Fits the Honda ATC's
