Sorry Silverone I disagree strongly with even the suggestion of this. In my opinion time has already told. The 103 was/is by far the better motor combination with more mileage on them before they fail or start to fail. 110= a 20-35k motor 103= 85k and still counting. Many people if asked would have bought their 110's with 103's given the choice especially after the first few years of delivery.
The '05 SEEG (PC III, K&N, stock pipes/mufflers) will smoke the '09 SERG (FuelPak, ThrottlePak, K&N, V&H PowerDuals, RSD mufflers).
The 110 is all low end and falls on its face around 3,800rpm.
'Just did the 50k service on the '05 SEEG, tensioner kit installed under warranty around 40k as preventive maint. (no failure). The drive train has been zero drama.
10k on the '09 SERG, no drama with the drive train yet... have had tire drama (F&R), handling drama.
The '09 SERG is in process of SE Stage III Pro Kit and Cartridge Forks. (Maybe then, it will run and handle as good as the stock '05 SEEG
)
My good friend just had to split the cases on his Skunk at 16k (probably rods)
I have a feeling that I will get a lot of use of the ESP on the '09...
