I was just throwing this out. I had bought a bottle of Lucas fuel system treatment for my truck. The label says Injector Cleaner, but also says it works with any gas engine, even small engines. Just cause I was bored, I threw 1 oz. of Lucas into 5 gallons of motorcycle gas. First thing I noticed was the pilot adjustment was a bit off. I had to richen it up by 1/2 turn. Not sure why, other than maybe the Lucas is slightly harder to atomize into the air. After running around initially, I didn't notice much. But, now I'm on my second tank of fuel with the Lucas in it, and my pig seems to idle smoother, has slightly less hessitation, and starts easier cold. My spark plug looks very clean, and the jetting is dead on. Not sure what you guys think, but it's pretty cheap stuff. A 5 oz. bottle is 3.99 and will treat 10 stock tanks of fuel, (25 Gal). I am undecided on whether to run this stuff full-time.
