I removed the emissions crap, and modified the design. My repair has held up for over 20,000 miles..
I ended up replacing the broken stock exhaust with an NCY, and I have another Vino in the shop where someone tried to reweld the exhaust, didn't align it right, and then decided to bolt it up anyway, breaking off an exhaust stud in the head and another in the case, and then broke off an eazyout in the head. He rode it like that for months until the original belt finally broke, because if it's running, it doesn't need any service.
