Harada #1101

The Harada page shows it using the "New A12" bolt pattern

But see some drilled with center hole (dual pattern) to fit the old A12 and the New A12/A13/A14/A15 heads

The flange will also cover the water ports so it can run on unmodified 1980s heads

Looks like it has two vacuum bosses, one already drilled & tapped for a fitting, the other one not

OOPS, won't fit the 1200's cylinder head unless you drill a center hole in each flange
Open in new window


will it fit with the stock cast iron exhaust manifold? Or will it require tubular headers/extractors


eBay $665 dual-pattern version, including all the small parts so no scrounging, no accepting "kinda works" -- everything just works, including insulator gaskets linkage, fasteners

Jeeze Louise...I'd love to have this brand spankin' new oval port intake/linkage to replace my baling wire & duct taped old one, but my Mikuni carbs (40s) are not the identical twin versions that work with this intake/linkage, but rather the rarer mirror image carbs where the throttle shafts exit on opposite ends of each carburetor. Dang. Foiled again.
