Performance ToolW80579 Flex Drive Compression Tester

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.

Very nice low profile adapter worked great. So much better than buying another tester ..... I worried needlessly these adapters wouldn't work with my different brand tester. But they did the trick !!!

Very nice product they work very well

Los use para el reloj de verificar la compresión de los Pistones y como todo vehículo es diferente tube q comprarlos...

Used this for an old Honda motorcycle that turns out to have low compression, very handy set of adapters.

I like the item very much

I like it and although it’s the only one I have been able to find while shopping ,I recommend it.

Hell ya it did! I bought it mostly for the Ford 3valve adapter. Which is the first one. The price is great! Any other adapter started at $20.00. Just for one. And got more expensive. Definitely a hell of a great buy!

Two 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.

I thought it worked great on my motorcycle, checked the compression all good.

A little priceyAppear to good qualitySomething that all compression testers should come with

Fits the Honda ATC's
