Yes and no is the answer. If its the stock KTM pipe it should not backfire, if it has an aftermarket pipe (race pipe) there is a good chance it will. You should make sure all the exhaust joints are sealed properly as this will contribute to it. If its a race pipe, make sure the bike has had the carb rejetted to suit. Genrally, with a race pipe you will get some popping when decellerating even if it has been set up correctly.

Check for vacuum leaks the rubber or plastic line may have a hole. Distributor timming maybe off also. Cracked cap or worn comtacts in the cap. Coolant temp sensor affects fuel trim aka rich lean conditions

97 gmc seirra 2500 5.7 misses and backfires on deacceleration


Is this problem only on decel does it have a stable idle An egr that is not closing on decel could account for missing even stalling but the backfire indicates excessive fuel in the exhaust stream and egr gas is inert and is only used to dilute the fuel mixture to reduce combustion chamber temperature and control the formation of NOX gases

I have a Yamaha dragstar xvs 1100cc year 2002 as seen in Vidio , it has straight through slash pipes on it , I've had bike 2 months and now it's backfiring loads more on decel , I'm told to change the


Backfiring on throttle-closed decelleration is usually caused by cold air being sucked into a hot exhaust systen. Check for poor seal where the downpipe meets the cylinder head, and leakage at any joints beneath the engine if it has a balance pipe. Hope that helps.

Exhaust leaks near the exhaust port can draw air into pipe on deceleration and detonate any unburnt fuel leaving engine, causing backfire and high temps.
An overly lean fuel mixture on the engine can make decel backfire worse too.

2002 VTX 1800 backfires recelerating


If the bike is fuel injected, the module should fix it. If the bike is carbureted, you don't need the module but you will need to re-jet the carb to enrich the mix.
