You mentioned in another post that you used to live in Colorado. When I was in Wyoming couple of years ago, I was getting 45 mpg @ 75 mph, with a completely stock intake, but only around 40 at sea level. The BARO sensor on these systems has quite a bit to do with mileage..more than in a car, since these are not feedback loop systems. When I was in the mountains of Georgia, last July, with my modified intake, I was getting over 52, but "only" 45 back at sea level...Last I looked, Florida was at or even slightly below, sea level...I'm thinking that might be your problem...

I recently changed over to the Spector air cleaner assy, this is the one with the round red top filter and red open element around. I run stock ignition and I'm getting ready to install NGK plugs that are 2 heat ranges cooler  than stock as the ceramics on the stock are quite white. After all, this is hot South Florida.

Agree that plug wires will not effect gas mileage unless the engine is misfiring.  I'd also check the air cleaner.  A clogged filter will cause it to suck more gas.

Try running some seafoam through the old girl.  I'm not arguing the plug wires don't need replaced - but plug wires are more likely to cause an engine miss than poor mileage.

Yes, thanks for that Troll!   Since the Drifter is an '04 that makes the wires 10 yrs old, even with only 19,000 miles, it's gotta time for replacement. Drifter runs good but for some reason gas mileage has dropped significantly in the past 3 years.

Here's a diagram from Partszilla... I don't know if the wires are removable   http://www.partzilla.com/parts/search/Kawasaki/Motorcycle/2004/VN1500-R4+Vulcan+1500+Drifter/IGNITION+SYSTEM/parts.html
Time for more research. This pic. seems to indicate the wires would be removable...
