Just a little comment about inspection of parts. (It's my industry). I supect the bar risers are made of aluminum. If so, Magnaflux (a trade name for magnetic particle inspection) isn't the appropriate method. It would be best to perform liquid penetrant testing if surface defects are the suspected problem. (sometimes called Zyglo, again a trade name). Internal flaws in the material could be found with X-ray or ultrasonics but I doubt the material would be subjected to stresses that would result in failure dure to minor interior flaws that would be in billet alumnium. Liquid penetrant is the way to go and the cheapest. If I'm out to lunch and the risers are made of mild steel then magnetic particle inspection would be good. By the way liquid penetrant can be done on steel too. There are some unscrupulous companies out there that would charge higher magnetic particle rates for penetrant work to the unsuspecting public. (oh by the way it's spelled Boeing)
I bought a set of Doug's risers .... the 2nd wave that was 'recalled' by Doug. I'm sorry I sent them back. But, it was Doug's request and I respect his decision and feel very badly for him. It was not his fault that some riser bolts failed when torquing them down during installation.
Here's my problem. As I remember things, it was not the risers themselves ... which are solid aluminum ... that failed. It was the new tapered bolds that failed when some folks installed the risers and torqued the down.
I did not use a torque wrench when I installed my Doug Hine's risers. I did the nut tightening as I do most things .... tighten and then a bit more. It's not scientific who really gives a rat's ass, eh. It's always worked for lug nuts, oil filters, and such. Anyway .....
So, the tapered 'after market' bolts were the failing part. NOT the aluminum risers. And, the design was first rate. Doug did a terrific job in his design. I think the manufacturer just got a bad batch of material for the tapered bolts. Shit happens. Doug took the rap and was a stand up guy when he voluntarily 'recalled' his risers.
I had NO problem with his design or materials. My risers did not fail when I installed them, nor did they fill in the several hundred miles I used them. I am sorry that I sent them back. But, Doug asked for them and I respected his recall request.
Soooo, altho I am no expert, I would guess that the failure of the bolts has not been examined. All of them did not fail. Just a few. And, they fail at install, not in service.
I believe that Doug's design for the 2006 risers was very good (altho, they could have tilted back a bit ... which may have compromised the cables somewhat), and they were an inexpensive farkle, too. I feel bad that these deals are 'off the market'. They were pretty kewl farkles for our FJRs for sure.
