Ich spreche kein Deutsch

My Name is Atli and i am from Iceland and i just moved to Hamburg, Germany, 6 months ago.
I bought a Suzuki GSX-R 750 2010 -3 months ago and i was testing the bike in Almeria, Spain,for the first time last weekend. What i found out is that the Suspension is not set up for me and it dose not work well for my weight (89kg), the previous owner had the suspension set up for him and he was maybe 75kg. He had the inner springs changed on the front, so when i was braking very hard i was bottoming out the suspension. The bike is setup for track riding only.
Also the was something wrong with the Power commander V (i think) and i need to have that looked at as well.
Do you guys know of any suspension company / Guy here in Hamburg that i can take my bike to and have it fixed?
Or maybe a Dyno-shop to check out the PC V
Thanks guy´s
