Welcome Tim to the forum
not as big as the old forum but its growing
has your MT had a full service since you've owned it plugs air filter not much point in my view of buying a power commander as they don't kick in until 3.500 rpm by which time the MT at its best if only the cans have been swapped it shouldn't make any difference to the fuelling unless the exup valve has been removed might be worth a good Dyno run see if that picks any thing up
Enjoy the MT and the forum don't forget we like photos as well

PS we have a few Aussie members on here who will chime in
Heres one of them. Hi Tim. At 20000 as Ash points out first service is due which is mainly plugs. There are a number of points to look at, can you spare a moment?
Air filter, if its standard then at 20000 it needs replacing. K&N is good.
Dam mufflers, wont make any problem with standard everything.
EXUP, on left near footpeg, has chrome cover. Remove the chrome cover and you will see the push pull cables. It may have been wired open, if not it should be. With that cover off and assuming it hasnt been wired then drop the cable that closes it and with bike running (dont burn fingers) open and close the exup, you will hear the difference. Its not causing any issue standard except it sounds like a 350

, wire it open and leave cables disconnected.
This next is important because you dont know the bikes history. When you start the bike cold does it start easy and does it turn over twice and almost seem to fail or does it start after a single turn? The answer here will give a clue as whether ecu has been flashed.
That will do for now
