Hello folks, questions from a noob.

[Samaha]

Good day to you all. I've just acquired my first bike, an FZS600 '02. The bikes ready to go but it would appear it was previously owned by a dwarf!? The seat has been shaved and is pretty uncomfortable, but I was wondering if anything may have been changed to lower the rear of the bike, I can stand over it comfortably with space between me and the seat? I'm 6'3 but surely there shouldn't be that much of a gap? Any advice or tips would be much appreciated. Cheers
