What finish are you gonna give that alluminium/Stainless? If I may suggest... Sand blast and annodise? Or are you looking to go the powdercoat root?
Just ordered the Vapor system as well. Should get it tomorrow hopefully! Hopefully not too difficult to install?
First ever I have heard of a DRZ 650 Ha ha but I think its gonna be kick-ass!
Let Suzuki know when you are done too!
