Now, the following is just an assumption, but it could explain your missing 1.1L of oil�
You say you changed the oil and added 2.6 litres. When you drained it, did you also drain the sump? If you didn�t then 2.6L would have been too much oil by about 0.6 litres (which is approximately the sump capacity). This excess oil would then have been blown out through the crankcase breather into the airbox, some will be inhaled by the engine and the rest (in fact most of it) will collect in the bottom of the airbox and its drain tube.
When you drained the oil (after 600 miles) 0.6L would have disappeared in the airbox (as above) making your original 2.6L now approximately 2.0L. Then, if you didn�t drain the sump the second time either, there would be an additional 0.6L in there too, bringing your original 2.6L down to roughly the 1.5L you ended up with.
Is your airbox full of oil? Did you drain the sump? Did you follow the add 1.9L, start and rev the engine a few of times, then top up with the remaining 0.7L rule?
Also, are you measuring your oil level on the dipstick after the engine has been running or a few minutes or after a ride, or are you doing it on a cold engine? If it�s the latter, you won�t see anything on the dipstick at all as a quarter of the total oil volume will be sitting in the sump waiting to be scavenged back up to the tank.

Very interesting reply there. Thanks for the input however the air box is bone dry. oil Im using is 10w 40 fully synthetic by the way.
Did the oil change exactly to the manual.
Original oil check again was done shortly after purchasing the bike. Did it to the manual..... Leave bike on tick over for 10 minutes on flat level ground before checking the dipstick. Could not work out why I wasn't getting any level on the stick. Then did the oil & filter change so I could then be certain how much oil I had in the bike (again following the manual)
600 miles later followed the procedure for checking the level and got nothing like before. Then worried I drained it all again (except for the filter which I believe holds approx 0.1L ) as I was so confused as to why there appeared to be very little oil.
Was then I measured only 1.5 liters that came out of both drain plugs.
The spark plug is very clean and shows no sign of burning excess oil.
The only thing that seems logical is I monumentally screwed up the quantity when refilling the oil after the change. I'm convinced I did the correct quantities. 1.9 liters in.. start the bike, blip the throttle a few times then fill the remaining 0.7 liters or so.
Also would the very sooty exhaust be any tail tail ( Doesn't agree with the spark plug) As far as I'm aware, allowing the engine to breath better with after market exhausts should allow the engine to run leaner. Could this build up of soot be from the AIS before I blocked it off with the blanking plate? The Kev fuel mod makes the bike run even richer (I don't have the fuel mod installed)
Appreciate the reply. This is all a big learning curve but just come at a bad time just before a trip!
