I'd give some benefit of the doubt on that. We've developed adhesives that live through orbital shots and reentry. My bigger concern would be using any adhesive on pieces that might come apart and come up the primary chain when it's up to all of us at home to recognize then do the requisite prep for the adhesive to work well long term.

Exactly! There are adhesives these days that will basically last as long as a good weld, so if the correct adhesive is specified that won't be the problem. The problem comes from prepping and applying the adhesive and parts outside of a strictly controlled process. Just telling someone to clean the cover, slap on some adhesive, and press the parts in place is a recipe for disaster. I'll be very interested in reading the actual instructions that come with this latest money maker for Harley. And you can bet if those deflectors come loose and jam in the primary good ol' H-D will disavow all responsibility.
Funny how the guy who invented the idea bolts his parts into the primary, but the folks who stole the idea decided to glue the parts to the cover. Was that an attempt to avoid litigation, or just the typical Harley cheapness coming through? I wonder how they will do this when it becomes the regular production version of the compensator?
This entire compensator deal is like one of those never ending soap opera's.
