Last few posts were great! Made me hook to the thread.
Bike at 19,000Kms, Recently started noticing a sound which comes while revving hard. Something like a metal clanking sound below engine bay, only when I revv instantly, clanks couple of times. During smooth acceleration, it seems to be absent. Service representative told there is no tapet noise as well which means no need to check valve seating and such minor clanking sound is normal.
Other than this sound, no other issues or any signs of other faults. Everything seems normal, compression test couple of thousand Kms ago seemed good. What should I be checking for identifying the source of the noise or is this really normal?
Check your belly pan clamps and bolts. A loose belly pan mount (the steel plate that mounts to the engine) if it's loose or the cowl bolts itself are loose, you'll hear mild jingling sound or clanking sound as you mentioned. Do have a check of the mounts and radiator guard.

Message received loud and clear guys - NO sealant on metal gaskets. Called the service center today for update on the head gasket and the guy told me that they've stopped manufacturing the old gasket (JY511070) and the new ones (JY511139) are compatible with the older dukes. Can someone please enquire with their nearest service center and confirm this? Or should I write to KTM ? Will they answer these kinds of questions? Just want to be absolutely sure.
Confirmed with my mechanic here. They are a direct fit. One word of caution he mentioned is to check and get the right gasket, as the 250 and 390 have almost similar gaskets, and it's easy to get confused. The part number you mentioned for the new gasket is right for the D390 and it's a direct fit for the older models i.e. 2015-2018/19.
Jokes apart, sealants can be used on paper gaskets such as clutch cover, magneto cover, valve cover gasket O rings, most of them go well with sealants if the right quantity is applied. But "NEVER" ON A METAL GASKET.
Cheers!
