I have the VH big radius pipes and bike ran great. I just put on the spike air intake from Big Dog. Now the bike stutters during accelerating and pops during deceleration. Do I need to change the jets? Also what would the recommended jets be for my setup? The VH pipes with the spike intake. 07 Mastiff with 117 ci.


It should already be jetted for the big radius, try turning the air mix screw counter clock wis a little at a time while riding until decel pop stops, idle may drop just adjust if necessary
