Maybe they compressed the stock spring, put on a shorter spring, or just cut the stock spring to lower it. Did they also cut the kickstand? I ask because my cousin just had her GSXR 600 lowered (with dogbone), but they had to cut a few inches off the kickstand so it would lean properly.
The kickstand is intact. The spring isn't cut. A friend of mine lowered the spring all of the way and it didn't move a bit. I have talked to quite a few people and so far no one seems to know what has happened to the bike. My next shot, is take it to a shop to have them figure it out, but of course I would rather not.
