Suzuki 2 Strokes

My bike is running crappy. It sounds like it's way out of time, but the timing is spot on. I am trying to test the coils. The book says it should read 4 - 6 ohms between each pair of wires coming from the corresponding coil. I am getting a reading of 39.2 ohms on all three. My meter only has a K ohm setting. Am I actually seeing 3.92 ohms? My meter is a very old (like 30 years) Radio Shack digital meter (Micronta).
It sounds like and feels like it's only running on 2 cylinders. But after a 2 mile test run, all 3 pipes are hot. I am 99.99% sure its not a carb related issue. I had them apart about a month ago to clean the gunk from the pilot jets. Thanks ethanol fuel . After that, it ran great. This just started a few days ago.

Edit: Who is a good source for plug caps?

My son brought his meter over. It has a straight ohm setting. All three checked 4.8 ohms - right in spec. I think my meter is toast. I tried to show him that my meter was reading 39.2. Now it is reading 13.9. Time to upgrade.

Chris, Suzuki still have those plug caps so you can get them. I bought some last month and the price isnt bad; your dealers cost will vary.

Coyote, it might be worth checking the battery in your meter.

What the???????????????????? This morning I get a reading 5.9, 6 and 6.1 ohms.

Really sounds like the caps are bad. I have seen several have the resistors fail like that, when cold very hard to start, but hot was fine. On a pressure washer had to put a non -resistor plug in to start it, run for a minute, swap back to original plug and go. Changed plug cap, now starts with OEM plug fine. It also sounds like your meter is bad too......

Chris, was the temperature the same each time you tested? Resistance goes up as temperature rises.
