The guage is nice. It holds the max compression reading and has a release valve to reset the dial. The tubes with rubber tips will not fit in the spark plug wells with the gauge attached. The bent tube will drop in but no way are getting the gauge on there in the center cylinders. The gauge hits the side of the air box when you try to press the tip down in the spark plug hole. The only way the rubber tipped tube will work on the 14 is maybe if you attach a hose with an elbow coupler between the tube and the gauge. Seems like this might work but they don't include that extra part so I don't know.

The hose with screw in adapter is tough to get the threads started. You have to work the hose like a flexible shaft and it will go in. A solid tube with an elbow coupler on the end would be better if you wanted to use a screw in adapter (this is how they show the process in the SM).

Do I recommend the Pit Posse compression tester for the 14? Well, it works, it's not expensive but has a few pitfalls for a 14. There's gotta be better setups available. One horrible problem with the Pit Posse, the screw in adapter with orings screws onto the hose (no coupler). If you tighten theadapter into the spark plug hole more than finger tight, you may well screw the hose out of the adapter leaving the adapter screwed in at the bottom of the spark plug hole. This happened to me and caused me a moment of messing my drawers. I LokTited the threads on the hose and dropped it down the hole to screw back into the adapter. Thankfully, a couple hours later, the Loktight held tighter than the oring pressed between the adapter and the bottom of the well. It screwed out all in one piece like I orinally put it in. I HIGHLY recommend you LockTite the adapter to the hose threads and don't try to twist the adapter in very tight. BUT...does the oring seal with just a little pressure? I didn't get very high marks on my compression test so maybe the seal was not so great.

Maybe I will try to pick up some couplers at the hardware store and get this thing to work right.

One more drawback, if the adapter does get stuck in the spark plug hole, forget about using a socket down the well to remove it. It is not magnetic so you would have to reltrieve it with a grabber or long forceps or something. I'm starting to dislike this tool more. It's good for a cruiser with external plugs but is not all set to go for the 14.

Here's the adapter. What would be required to snug the adapter in nice and snug would be a solid tube. Then attach the hose to an elbow coupler on the top of the tube.

As you see, I have the hose dropped down the well. I had to tighten the adapter into the spark plug hole by twisting the hose like a flexible shaft.
