Carburetor from Japan: Mikuni

There are many authentic photos showing the XR 750 with two Mikuni carburetors. "What's good for racing can't be that bad for the road," thought the bikers and successfully fitted round slide carburetors from Mikuni to their bikes. The good reputation of the Japanese carburetors on classic American iron was well founded and is also justified for the flat slide carburetors of the HS and HSR generation. These carburetors are a good alternative to worn-out original carburetors and can be adjusted without specialist knowledge.

In addition to carburetor kits in 34, 40 and 42 mm passage, we offer all jets, spare parts and gaskets. The carburetor kits come with the appropriate jetting for the intended use. With our jets and tips from the Wrecking Crew, anyone can tweak their performance.

We offer accessories for Mikuni carburetors such as air filter covers, throttle cables, carburetor and air filter supports, adjusting screws and much more.
