f4i backfires?
i recently installed the o2 sensor eliminator and have a D&D slip-on exhaust. with the D&D i noticed at higher rpm's it will create a popping or backfiring type sound, im talking like 10+rpm and letting the throttle go. is this normal for F4I's? I know with the stock exhaust it didnt do this, but is it normal to change out to a louder exhaust and hear this?
if this is a problem what are the effects on the bike's health? and how to fix? thanks. |
Re-map needed. Some here may tell you that it's normal... but it's not.
|
Yeah, I've heard the sound too, but my bike is sitting for the winter, so I'll see next season.
|
Its a lean condition and its quite bad on the engine.
|
yep it's lean
lean means it'll rev a little bit faster and may idle a little high otherwise you'll get the popping sounds, possibly foul plugs if it's bad enough, and your motor will run hotter |
aite thanks for the responses, after riding it a bit more and paying closer attention to it, it seems to happen on upshifts when i push it hard and do a quick up shift or during deceleration and i let it engine brake. how would i make it run less lean?
edit: im sure it aint actual backfire with flames and all, its just popping quite a bit |
power commander
then download the closest map to the mods on your bike (not sure if a D&D is one of the maps, but if not just pick another slip on brand and it'll be really close) |
^ +1, worked for me as expected
|
any one with a power commander for sale? lol
|
Mine backfires to and at night flames bubble out on deceleration. I have a Jardine RT-1 exhaust.
