My 2012 was sitting in some showroom in Australia. manuf year 2011. No Aussies wanted the poor thing. So some dealer from Malaysia bought it and I am the 1st owner of a brand new bike, bought in 2015. Tires were made in 2010. All together 4 years sitting.
Issues found: None. No leaks whatsoever. Front tire eventually started showing signs of cracks sometime in late 2016, very minor. I had it changed in March 2017 right before a major trip, and I had put it 11k km on it. Metzeler Tourance EXP. Rear is still good, so will wear it out normally. Even the battery is still good till today.
The very first thing I did to the bike was to run it hard Motoman style, then go for a oil change. I am pleased to say, the bike doesn't consume oil (10W40) after the 1400km trip recently. (Mileage was 11k km before the trip) I did find some traces of oil in the air box (very little), which I believe comes from the crankcase vent, which I never noticed before for the 1st 10k km (because I haven't rode at a maintained speed of 130 to 160kph for hours). I also noticed traces of oil at the throttle body barbs when I was TB sync'ing. I cleaned it with Carb cleaner, shoot into the barbs to clear up any grime.
Oil change, measured 3.4L or 3.6 Quart of new oil. Drain out all oil from the 2 drain holes, change filter. Pour in 3.4L and done. This dry sump thing has a magical show on the sight glass.
I had the clutch and brake fluids and coolant changed at 10k km. Brake fluid was amber which had me concerned that it is old and no good but it is untrue (there are DOT4 amber fluids available), as it never gave me any issues. But changed it anyway ASAP if you can because of the nature of the fluid to absorb O2 and deteriorate over time. I dare not touch the brake fluids because of the ABS system which I wasn't familiar with and I don't trust workshop mechanics with it (ABS system and also they don't quickly wipe off the leaked fluids off painted parts). some research allowed me to cast away all fears and a DIY sorted it out. Just remember to Cycle the ABS pump via a certain procedure, and then change fluids one last time.
Don't have to worry about lubing the chain. I had the pumpkin oil changed twice, first at 1k km with a mineral gear oil, and at 2500km, with fully synthetic gear oil, API GL5. Does makes the pumpkin quieter.
