[Gas gas newby]

hey all, i am new to gas gas ,i just bought a 2006 ec 250, ive got to say i love this bike it feels so light and nibble , and the suspension is awesome , the only problem I have is I am quite short and would like to lower the bike about an inch but dont want to go down the road of altering steering and suspension geometry . My first thought was to shave some foam of the seat as i have done this before many times on other bikes , the problem is although it look like there is a good three inches of foam on the seat , because of the seat design there just isnt enough foam thickness to play around with.

Does anybody know of anywhere that makes a lower seat for the gas gas i can find them online for the newer models but not for the 2006 or will the later model seat still fit ? Any help would be greatly appreciated
