I have a Rev-Tech DFO installed with no instructions. I used the instructions from Dobecks web sight that where intended for the Gen 3 I think.This unit was made by Dobeck so every thing seems to be working out find. Is it unreasonable to think that the Rev-Tech DFO would help stop some of the popping on decel? The bike runs cooler. The oil tempt is cooler. The over all feel of the engine's performance seems to have improved. I have searched these forums to I'm cross eyed and tried a lot of different things but to no avail. I think that maybe changing out the mufflers & header pipes to a one piece unit might be the next step.Does the decel popping hurt anything ?
