Hi, I dont know if the sv650 is the same as the sv1000, I have a 03 sv1000 and it used to pop on the overun the whole time even after fitting the power commander and getting her dyno’d.
The problem on a lot of bikes, mine and probably yours is what’s called a P.A.I.R system or pulsed air injection which is strictly there for emmisions laws and has no effect on performance whatsoever, because with the aftermarket exhaust your bikes gas flow is different, this system is designed to send more air to the cylinders to help ignite any unburnt fuel so it does’nt kill us all when spat out yer exhaust, this is what causes the popping.
I got really pissed off with it after a while and so ripped out the whole pair system, the solenoid, everything, and blanked off the plates on top of the cylinder heads, problem 100% solved and bike runs smooth as.
Hope this helps you out a bit mate, oh, and sorry if it’s all seemed a bit long winded:w00t:
