Compression Tester

[Tekime]

I'd like to replace my compression tester but not very keen on spending $100-200+ on an infrequently used tool.

Was checking out this Lisle tester and the Pit Posse. For $40 on Amazon the Pit Posse seems like it might be the way to go.

Any other recommendations?

I think I got mine at Autozone?

[jasnmar]

Yeah, like less than $40ish seems right.
Of course I don't know why you'd want to replace one.
Just test the one you have. If it works, keep using it.

Have an old HF one that I only used a handful of times, but tried on multiple running bikes and only ever hits 35-40psi.

Try replacing the Schrader valve in the hose first. It should be the same as any tire valve stem.

I like my OTC Deluxe. Can be had for $66ish, or the basic one for $55ish.

You get better results if the bike isn't running
The Schrader valve in the hose may be either hanging open or clogged with crud. They're a special low spring pressure design so the compression pushes it open. NOT a tire valve core.
I use an OTC 5604, but they're closer to $95 than $40. No experience with the Pit Posse. Lisle is generally good, but the attached hose and extra purchase adapters are weird.

*scooped by chicken while looking for the part number.

yeah $40ish is what I spent too...just went on amazon and got the one with the best blend of reviews/price for the 2-smokah

I just put my thumb over the hole, if it pushes it off, good to go.

Yeah, I bought one at autozone as well.

I also have an OTC kit. And it works well.

Be ware that for bikes you want the OTC 5604 kit Doug mentions. Not the OTC 5605, like I bought. The 05 kit has different adapters and doesn't work as well with deeply recessed plug holes.. like those you find on OHV engines.. which almost all motorcycles are. I make the 05 kit work, but get the 04 kit instead.

I spent closer to $70.

Calling BS. We all know you just rented it for a day.

Well now you tell me, you know how hard it was to get that reading?

That OTC looks like a nice little setup, a bit pricey but not terrible.

I became suspicious of the Pit Posse when I noticed they sell my $10 Harbor Freight digital calipers for $35.

i have a brand new, unused, INNOVA 3612 comp tester i can't use due to space issues on the RR. the adapter is too long, i can't fit it under frame.

if you're interested, let me know. i'd be good with shipping + 2 bucks for a roadie in return (?)

[Tekime]

Actually I pulled the trigger on that OTC 5604. Looks pretty solid, exactly what I need, and hoping I'll have it in the toolkit for a lot of years.

Thanks guys

Put it in the go-kart and the next time you're blasting through at mach 1.5 along 195 stop in and I'll provide enough roadies to make your final approach questionable.

[Tekime]

wth is a roadie anyway? Asking for a friend

Man I should have...used twice in 4 years

I fix cars for a living and I've only used mine one more time than you have in the past 4 years.

[Tekime]

Satisfied! Nice little setup.
