with a back pack you cannot expect anything more than 210kmh...
try in "perfect" conditions (i.e. tucked behing the fairing, leather suit, perfectly tuned engine, 20 deg.C, correct tyre pressure, etc etc) and in a good run you should see a little bit more.
To do the "in theory" declared MAX SPEED of 230Km/h with a 31/62 primery gear, 15/40 secondary gear (the standard) and a 170/60-17" tyre, the engine must rev over 8750rpm in 6th gear (28/24) which I see it to be quite difficult.
With the 15/39 the gearing is even too high and it is unlikely the engine can pull it.
I found that the 15/42 works much (MUCH) better, but I use the bike 99.99% on twisty roads (the Alps)
As for the OIL Leak, there are some oil passages in the Cilinders and the seal is made through a small OR wich sometimes leaks; I had the same on mune, and the only solution is Stripping the rear Cilinder and replace the sals making sure that during assemply the OR is correctly fitted; In any case mine has never beed very clean, not dripping oil but not dry neither...
But the Italian correction will give max 220 km/h for real.
