    Change handlebar height

    Can I change the height of the handlebars on my Agattu B8? I know I can swivel them but I'd like to raise them vertically a couple of inches. The dealer told me it can't be raised but he was wrong about some other things.

    Has anyone had any issues using the badass box with and evo motor for Kalkhoff Intergrale?
