[QUOTE="SPEAKERMAN, post: 95159, member: 120"] So here's the low-down on these devices: 1. If you bike is jetted poorly, has an old plug, has old plug wires, adding a spark booster or a power now will show an improvement in how your bike runs. 2. The devices are not snake-oil, they are not scams, they are not bogus. They are just not needed, if your bike is jetted correctly! 3. Making a hotter or longer spark has NO EFFECT on how the gases burn. The spark is not part of the combustion, ONCE THE COMBUSTION BEGINS. But, if your plug is whack, your gas is crappy, or your valves leak, it would show and improvement. 4. The powernow device is designed to MAKE YOUR CARB VENTURI SMALLER so the intake velocity inside the carb speeds up. This gives you improved throttle response at low rpms, making it SEEM like you have more power. Unfortunately, if your carb is properly jetted, the accelerator pump is tuned to perfection, the powernow will make the bike run WORSE. It will also mask carb issues, which may get worse on the trail. The bottom line is, short-cuts don't solve problems, they mask them. Fix the problems and move on. [/QUOTE]
