Heres the link to that Remus BMC flapper door mod. Remus exhaust + BMC filter = holy SHI....!
Is that flapper mod just letting more air in? Which would mean you need more fuel, right? |
Yeah the throttle adjustment is an 8mm and 10mm nut on the throttle cable near the grip. Break the 10mm locknut loose then turn the 8mm nut to adjust. Turning it to expose more thread tightens the cable.
Regarding the flapper door on the airbox--At low RPM, the flapper door is supposed to be closed. This ensures slightly higher air velocity into the airbox which is helps boost torque by a marginal amount as well as increase throttle response (which might not be a good thing). Think of it as a miniature faux-ram-air effect.
At higher RPM, the flapper door opens because the engine is actually able to use the potentially higher volume of air entering the airbox. Plus, the extra noise generated is kind of nice. One thing to keep in mind is that the flapper door is not a "throttle valve"--it does not
limit the amount of air entering the engine at low RPM... if anything it helps boost the amount of air, if only by a small amount..
If memory serves, the flapper door is supposed to open at somewhere just over 5000 RPM.
Disabling the valve would probably result in a reduction of power/torque at low RPM on a dyno, but it might tame the throttle response at low RPM? I don't know...
