![]() ![]() The big HP is easy to get for any tuner that knows a little bit. ![]() I will not release any tuning program to anyone until it passes my personal picky standards. Throttle response needs to be smooth and predictable. and at all throttle positions, including max power at full throttle. The rest is your riding skill.Ī street rider or road racer on the other hand, needs everything to be as perfect as you can get it. If it runs just ok at part throttle, this is good enough. You just need the wide open throttle to be fine tuned and not much else. If your primary riding is just at the dragstrip, you don't need an engine that runs perfect at all throttle positions. Ivan himself on his website even says this.Īdding a free intake will result in the most HP, exhaust adds about 2 to 3 HP. The Flash was never about horsepower, that is a huge misconception in the internet world. After the flash you have to re-learn the bike because it is completely different in a great way. The Ivan' flash is the best mod you can get for a V Star or any of the fuel injected bikes he works on. Allows the radiator fan to come on at a lower temp to promote better cooling during stop and go. This causes hard deceleration, backfiring and popping when using less restrictive exhaust.ĥ. Disables "fuel cut" Fuel cut is an EPA mandate to have the fuel injectors turn of every time you let off the throttle above a certain RPM (Idle). Results in more power in the lower RPM range and runs the A/F at the correct range instead of the over lean factory condition.Ĥ. Enriches and leans the fuel tables/maps as needed. Adjusts the throttle mapping for a smoother roll on instead of the ON/OFF behavior of the throttleģ. This also allows the engine to run cooler and produces less heat and vibration.Ģ. This helps eliminate the surging and lack of torque at lower RPM's. Advances the ignition timing throughout the power band. A open air intake and exhaust is where you will see the increase in power. Ivan's flash is not for power like most mistakenly assume, it is for smoothness and ride-ability.
