High Performance Plus markets two products: an oil additive and a fuel additive . So far, we've treated six bikes…a 1994 Honda VFR750 with a Two Brothers pipe and a Factory jet kit; a 1995 Yamaha YZF600R, totally stock; a 1994 Kawasaki ZX-7, also stock; a jetted and piped 1989 Yamaha FZR600; a stock 1979 Honda CBX; and finally, a 1993 KTM 250 dirtbike. All except the VFR and the FZR showed a substantial 'increase in power as seen on a Dyno-Jet 150 dynamometer. All bikes were warmed up in preparation for a baseline run. Next, a half-ounce* of oil additive was added to the crankcase of each bike. The engine was run through the gears and re-tested. Then a *half-ounce of fuel additive was put into the tank and the bike was again run through the gears. After the additives were thoroughly distributed, we did fourth-gear roll-ons to measure rear wheel horsepower.

The increase was startling for the " ZX-7. The Kawi made 97 horse power at the rear wheel in stock condition. After treating both oil and fuel, peak power rose to 102 bhp. The increase wasn't just at the top of the rpm band, but throughout the operating range, with the greatest increase seen at 7000 rpm. The ZX had shown a definite dip in its powerband. but after treatment the dip turned into a peak and horsepower went up by six. Owner Chris Lypka said his bike felt stronger particularly in the 7000-rpm range-as the dyno had shown. 

The next largest increase came from the American Roadracing test YZF600R, which has always been less than a stellar performer. The YZF has been on the dyno many times, and the best it has ever done is 79 bhp quite a bit lower than the 84-85 bhp that we've seen from other YZF60ORs. Seat-of-the-pants testing verified that this Yamaha is simply not in the 90th percentile of its class. After treatment, the 600 climbed to an all-time high of 84 bhp. Riding confirms that this is definitely a happier motor, more willing to rev and making better power throughout the entire rev range.

Finally, the venerable CBX. This bike has had very little maintenance over the years, largely because it never seems to need any. With 37,000 miles on the odometer, the big Six put out 80 horsepower to the rear wheel. We chose the CBX primarily to test the oil additive, because few motors have as many moving parts and bearing surfaces. Also, the "X" has proven to be sensitive to the fuel it uses. After treatment, the 24-valve mill made five more ponies from idle to redline. Riding confirmed that it did seem to run slightly better. . . . . .As an avid Supersport fan and competitor, I'd be overjoyed to pour something in my tank that would give me an edge (particularly if it was legal!). . . . . -Michael Ross

* The MMI treatment ratio was only 1/2 ounce of oil treatment per bike and 1/2 ounce of gas additive per bike. The treatment ratios are not the the treatment ration recommended by High Performance Plus. The recommended treatment ratio is 1 ounce of oil additive per engine and only 1cc of gas additive per gallon of gas. (added with an eye dropper!).

He said "this is KICK ASS GAS AND IT REALLY WORKS" . Our friend Chris was listening and broke into a story about he and Mike the night before and how his acceleration was out of sight on fourth gear. "It'll give you four extra horsepower guaranteed I heard as I started my bike.

Yeah, I nodded and smiled and headed for the gas station to top off thinking I'd take a short ride for shits and grins just to please Mike.By the time I got to the Cactus and 32nd St. intersection, a quite busy one, the motor was running perceivably smooth with a snappy note and it didn't try to kill at the light. I snapped it and began climbing through 3rd gear when pop, pop, pop - the system seemed to be dying - yet it was only momentary and I shifted to fourth - rolled on it and WOW - I had power I hadn't felt since three years before with 120+ octane aviation fuel. I turned around and made like a drag racer between 36th St. & 32nd St. on Cactus, actually wondering when an EVO might wander by so I could  race 'em. With little traffic, I screamed through the gears feeling torque, power, and a crisp note humming from my drag pipes 

The approach to the Cactus and 32nd St. intersection caught me off guard - I was accelerating - hit 60 and shifted to fourth gear - the crescendo building as no hesitation interrupted this powerful roll on to fourth - the unworldly horsepower in fourth caused me momentarily to not want to stop at the   intersection. A wicked tickle drove my being as I for one instant felt like just not stopping. I had to fight for my senses and decelerating – found my way home.

First thing I did was call Mike at the shop - he said, "I know--it happened  to us and I wanted you to share the experience." I asked if this were legal - like slanimin' your bike fulla crystal - lie said, "Yup and I got it here at the shop and I got the oil treatment for you that'll  give an extra two horsepower”Well I’ll tell you the rest of the story:

I got the oil changed the next day - Mike added the stuff and I did notice  instant improvement over the horsepower I'd already picked up. And you  can do it yourself! With an EYE DROPPER! Very potent – very cheep – hell how can a shovel head do without it!
