Here's what I use and they work really well.







Years ago I had a set of these (below) and they were crap; very inaccurate as readings were not at all consistent!

Warren, that is clever and balls on accurate, no pun, ha. I used to do a lot of footers and retaining walls years ago, had all the lasers for different directions. But.. if going around a blind corner used the ole clear tube filled with Gatorade trick. Perfect in simplistic design and 100 percent accurate.

This is from another member. Not sure where he bought it but look similar to the eBay sold dial your talking about. These might have just had a gorilla for a mailman but still be wary of cheap eBay items. The ol’ Saying goes you get what you pay for.

I use the Morgan Carbtune.

Cannot people waste their money on those cheap individual analog gauges on a blue tin plate?? Biggest POS ever made. i and everyone could just as well do it by ear. The only redeeming fact is they come with the adaptors for Suzuki and some Hondas. I have an unused Mercury carb stik somewhere but no Mercury. Can you even buy Mercury anymore??? Or would a person need a special permit and background check?

Are the cheap dial gauges not adjustable?. Can you hook all gauges to a 5 port fitting, run them to one carburetor and adjust all 4 to match. It makes no difference if they read vacuum accurately, as long as they are consistent.

You can do that, they have valve in the vacuum tube similar to the sort of thing used in aquarium air supply or the ones I saw did, only trouble is next time you use them they will need syncing again. You can connect dial 1 to carb 1, take reading, disconnect, reconnect to the same carb and get a different reading. They are a total waste of money.

Yes but you would need to remove the face caps and calibrate at the range of functional operation. I think those are superglued on. I had a set i had gotten from ww grainger and those you could calibrate from a single vacuum source so they all matched at a certain range.

Kaylinator is the member I pulled the picture from. He said like asphalt900 mentioned, he would have had to pull the needles off to try to calibrate.

The problem I had with the cheap gauges was that the reading on one of them was WAY off and fluctuated badly. That gauge was not usable at all. Of course that then made me question whether or not the readings on other gauges were consistent or accurate enough to be useful. I have not had that or any other problems with the better set of gauges. I've hooked them up to different carbs on the bike to check them out and they seem to be very consistent. Ed

Asphalt900, I’m sure you could get Mercury if you claimed you needed it for a peaceful protest.

Some places were still selling mercury as available, but it doesn't last long.

Just had a read on Your attached KZ550 Valve Train precautionary measures loudhvx, Very Informative, Thank-You! I don't see a lot of the small bore Kawi's but Now i Know where to go to gainer info if needed!
