Where can I find a compression tester?

What kind of compression tester do I need for my new back in 1996 GSX and where can I find one?

The gauge from Harbor Freight works OK. You can get it on sale for less than $20.

My buddy picked up a cheap one from an auto parts store and it sux. I get a different reading everytime. The seal setup on it SUX!!!

I perfer my old school push down type from the 70s. No threading in and out, and it surprises me everytime how accurate it is.

I'm about to get a snap on though...I got too many machines coming in these days to be using a cheap one.

I have a snap-on truck that comes by work every week. Let me know if the one you ordered is good.

I have one of those old push in gauges in the tool box. They were great for a quick check on older engines. I think it got retired because it won't reach down into most modern 4-stroke engines. (especially on Motorcycles)


You are right about about the crappy seals.

Regardless of how good of a tool you have... ALWAYS CHECK THE O-RING ON THE TOOL !!!!! Over on "G r e e n h u l k" there was a guy who pulled the top end apart of his engine because it was running bad, and his "Known Good" compression tool said it only had 60~70 psi. After getting it apart... he didn't find anything wrong... and after 2 or 3 days of making posts... he found the O-ring was split on his coupler. (on his compression gauge) :rofl::lols: After putting it all back together, we figured out that he still had Tempo fuel lines, and his carbs were plugged up.

The Snap-On gauge is a great tool... but it's $300. It's a nice Jeweled gauge... so, once you drop it... kiss $300 good by. I have a good MAC gauge... but I use my HF gauge for "Day to Day" operations. If you buy a cheap gauge, and think it isn't right... just hook it up to an air compressor and see if it matches the pressure on the regulator gauge.
