KLX 250 FI + FMF Q4 backfiring!!!

Enjoy some cool "fireworks" made in Kawasaki!!
This happens only in very cold weather (below zero celtius) and with the bike just started. After a minute of riding no more flames, but still some rifle shot here and there!! :)

So this is just a slip on?

[namphu]

[SoLaDoRoS]

hello, i would like to ask something about your system, is it full ? and if not, what do u got, powerbomb or megabomb??? have u changed anything in your filter system or any kind of program? plz let me know, thx.

[namphu]

@SoLaDoRoS

No, only silencer, and no other changes to the engine or injection (as i say at the end of the video...)

@namphu

Good, thx for info, i got a KLX250S and i am looking forward on buying one... In order to remove the silencer is it easy thing to do? And one last thing, what about spark arrestor? have u removed it in order to get those fireworks???

PS: so its a slip on Q4 with default mid-pipe and removed silencer, right? Sorry for asking that much but i wanna know exactly...

@SoLaDoRoS

How many questions dude!!! Just buy it ;)

Anyway yes the header is the original one and the q4 is a slip on.

To take off the baffle it takes 30 seconds. Is just a nut and the inner silencer comes out.

What is the tail light you have installed ?

@SoLaDoRoS FMF POWERCORE 4 + MEGAMBOMB is ther brutal combination...grab it now...

i thought that the Q4 had a spark arrester so it couldn't shoot fire?
