I bought your product yesterday, at the recommendation of a local motorcycle shop. I was basically looking for a fuel stabilizer that could counteract the effects of the ethanol in our fuel, when we put up our bikes for winter storage. I had understood that Yamaha also had an additive (Marine Division)that could neutralize ethanol\'s effects in long-term storage of gasoline, but the shop only had your product. The parts guy knows me, and told me they felt that yours was a better product. The rest is history. I read your little brochure that night, and came away with the impression that a lot of pretty bold claims were made. But I decided to test it out the following day anyway, figuring that if it would start cleaning the fuel system, as the brochure claimed it would, we could put up the bikes for winter with cleaned out fuel systems. My wife rides a DR650 Suzuki, I ride a 2008 KLR 650. The bikes have 15,803 and 2806 miles respectively. I added 1 ounce of your product to the KLR\'s ~5 gallons of gas, and 2/3rds of an ounces to the DR\'s full tank of 3.4 gallons. We started our ride. I did not expect much, if anything to manifest itself. I have never, in my 37 years of driving (owned 29 cars) and riding (owned 11 motorcycles), gotten any noticeable results out of anything in a can or bottle of fuel additive. Nothing. Ever. And I have tested a lot of them. All I cared about now was how to mitigate the bad effects ethanol has on carbed bikes over the long winter. We started our ride. After about 5-6 miles, I thought I noticed that the bike was running smoother in a higher gear with a lower RPM (with the engine NOT shuddering, surging or bucking). I figured it was my imagination, perhaps psychologically looking for a difference that I figured would be there, just because I added a can of something-or-other to the fuel! We got to our interim destination in about 8 miles, then continued riding. After about another 10 miles, I noticed that I was using the next higher gear than was usual for the speed that I was doing! Normally, I listen to the engine revs and sense the chassis vibrations, and determine that I am in the RPM range to carry the next gear for the road conditions ahead. Then I shift. Standard operating procedure! But I found myself in 4th gear, at 2400-2500 RPM, with the bike running impossibly smooth! No bucking, shuddering or surging! This was on level pavement. I was even able to coax a small amount of acceleration (without downshifting) with a tiny bit of twist to the throttle! There is no way I have ever been able to do this before. The engine would buck, shudder and plainly let me know that it was not happy. KLR owners out there know exactly what I am talking about. (My bike is 100% bone stock). I even approached a minor grade in 5th, at the same speeds, and was able to twist the throttle a tiny bit to maintain my speed. The motor did it with no problem! I knew then that it had to be your gas additive. No doubt in my mind whatsoever. I though about asking my wife if she noticed any effect on her bike. But I figured she wouldn\'t notice any difference, not seeming mechanically minded and sensitive about an engine\'s running attributes. But I asked her about it anyway, later on. Boy was I wrong! She said that her bike was also running super smoothly in the next higher gear than she always previously used for the same speeds! In fact, in one turn, she thought she had downshifted from third gear, when she was actually downshifting from fourth! This is exactly what happened to me. I took a 105 degree corner at 20 MPH in fourth gear, with the engine pulling away with perfectly smoothness with moderate acceleration!! I had thought I was in third gear approaching that corner. Before I knew it, I was trolling some of the country dirt roads at 30 MPH in 4th gear, which I have never done before! It was quite an adjustment (read embarrassing) to have to rethink our shifting points all over again. It was that dramatic. Additionally, my hands never got numb once during the 86 mile ride! This was impossible and unthinkable. At least 5 separate times during the ride, I tried to detect the vibrations that normally come through the grips. My hands usually numb up about every 10-15 miles at higher RPMs. I was wearing non-padded leather gloves. I usually take my hand off tthe grip for about 5 seconds, and the blood flow comes back! I determined that the vibration level of the left grip was ZERO, and the right grip\'s vibrations were 98% non-existent. I was essentially blown away by all this. My wife and I were also in agreement on the issue of way more engine smoothness than usual at very high RPM\'s on the faster roads we were on. And all I wanted was an ethanol mitigator. Essentially, I still can\'t believe the change in the motor\'s smoothness, and the vibration reduction of about 90-95% in the grips. Your product has worked wonders to the extent that I am still taken aback by the fact that I need to relearn shift points! One really has to experience that to understand it. The effects were so overtly obvious! I have drag raced at the track, ridden enduros, amateur motocross, and dabbled a bit in trials riding. I know how to shift! The paradigm has now changed for me, and it is due to your product. Now let\'s hope it does the same thing with mitigating ethanol\'s nasty effects in gasoline storage! Best regards.
