I've seen those, and I'm sure they work well. But the look is not even close to OEM. And for that kind of money you could probably buy a complete set of manifolds with good rubbers. Maybe two
1978 custom GL1000
1977 custom with 1200 engine
1985 gl1200
Rob, what are the numbers on those new manifold rubbers? Please let me know all of them. Either here or in a PM. Thanks
1976 Goldwing Super Sport
1985 Honda Elite
1976 KZ900 Dragbike
1992 ZX7 Dragbike (KZ900 style motor w/NOS)
and a rotation of various purchases
