Questions & Answers


Can I mount the Trask Assault Charge High-Flow Air Cleaner to a Mikuni HSR42 with this adapter?

05' FXDX(I) (converted to carb)

Yessir! That's exactly what this adapter is designed to do!

I have a mikuni carburetor, I bought the Arlen Ness big sucker stage 1 breather, it's obviously the wrong one to bolt on, Will this elevate that? Or do I need to get another breather

There’s no bolt on holes on the carburetor, and the new backing plat has about a 1/4 inch gap between the carburetor and the Arlen backplate

If the bike you have is fitted with a Mikuni HSR 42, HSR 45 or HSR 48 carburetor, then this is the kit for you since your '94 FLSTC rolled off the factory assembly line with a Keihin CV carb. With this adapter, the Big Sucker you'd previously purchased from us to fit your '94 FLSTC should fit your particular configuration without issue.

Is this strong enough to hold an S&S teardrop air intake by itself without any further mounting hardware? Thanks.

You would still want some type of support bracket that mounts to the breather bolts such as the Drag Specialties Carb Support Bracket for Mikuni HSR 42/45.
