Ok, I was able to adjust the rear shock with the help from you guys...And when i've finished i looked at some pictures of the GS bikes i have on my comp.  I know that on the tail of my '01 Suzuki stands sticker that says GS500E.While looking at the pics i saw the same looking bikes ( or i think so ) and there stands GS500 on their tails.Is there anything diferent on bikes that have "E" and those that don't?
Or is this a stupid question?  :dunno:

At least in the US it is:
'89 - '00 = GS500E
'01 - '02 = GS500 (lightly redesigned bodywork, carbs,...)
'04 + = GS500F (with fairing)

Maybe this is how they were designated in the US only, so yours is still designated as a GS500E in Serbia :dunno: (I do know the F is the F anywhere, and the GS500 continued production past '02 in many areas)
