Hm, is anything holding the AFM? Or is it just resting there with the air filter? Seems like it's twisting the heck out of the rubber intake hose. One could easily make a bracket to hold the AFM from a 1" wide piece of steel bent to an 'L' shape. Dril two holes on the bottom to bolt to the former aircleaner studs, and 2 bolts toward to top to bolt the AFM to.
