I SCORED these 2 weeks ago. It took the seller a while to get them to me, but it was worth every dime (about 200 of them with shipping).
I appreciate how someone dispensed with precision and simply blew a hole through them with a torch. Workmanship is so overrated.
The friction ridges have been omitted allowing for "on the fly" position adjustment. Is it two bars-or one??
This "custom" slot is for the internal throttle cable and slider. Without going into a detailed explaination on how it's works, lets just say, it won't.
The Ebay pic was blurry and too far away and the description in the auction weird, if not vague. I bought them on a gamble as vintage Honda bars are like hens teeth. At least I got a good laugh.
