Really hoping one of you knowledgeable folk on here can help as I'm having issues with the bike popping on tickover (tickover problems seem common for the nx650 by the looks of things). Sometimes the revs will hang high after small throttle input and other times the revs will drop and die but on the occasions that it does tickover there is an erratic popping coming from the exhaust.
I've tried to take a video to show what I mean if anyone can help.

The current setup is an iridium spark plug, direct mount Ram Air pod filter, stubby 2 into 1 scorpion exhaust (no baffle), 60 pilot jet with pilot screw around 1.5 turns out and a 170 main jet fitted after the carb was cleaned. There are no air leaks around the inlet manifold that I can find (squirted while running with WD40) and the bike runs fine other than the tickover issue. I'm guessing I need to replace the pilot jet again but without a gas sensor I don't know which way to go.
Other work already done in case it makes a difference. New CDI unit and coil pack fitted by previous owner.
I haven't yet shimmed the needle but I'm not sure that would that really affect tickover as I always thought that was controlled by the pilot jet and adjustment screw?
Cheers.
