        Description

        Features:

        • The Mikuni RS Series Carburetors were designed and built in response to the needs of the worlds top motorcycle road race and drag race teams.
        • They required carburetors which could satisfy the precise fuel metering demands and high flow volume required by highly modified race engines.
        • And yet, also provide the smooth, controllable throttle response that is needed by any rider pushing his motorcycle to its limits on the race track and under any high performance applications.
        • The carburetors need to meter fuel correctly under a wide range of atmospheric conditions and engine tuning modifications while being easily accessible for trackside tuning changes which need to be made quickly.
        • Designed for in-line four cylinder performance motorcycle applications, the Mikuni RS Series Radial Flat Slide Carburetors offer superior horsepower gains with their maximum flowing smoothbore induction tract and radial flat slide design.
        • An adjustable accelerator pump system helps to provide instant throttle response, particularly in the lower RPM range.
        • The RS Series Carburetors feature a compact design which is 25 percent lighter than other performance carburetors and uses readily available Mikuni jets.
        • Available in 34, 36, 38, and 40mm sizes.
        • IMPORTANT: Mikuni RS Series Carburetors are legal in California ONLY FOR RACING VEHICLES WHICH MAY NEVER BE USED UPON A PUBLIC STREET OR HIGHWAY. In other locations check for similar laws which may apply.

        Rated 5 out of 5 by from Awesome on old school GSXR! Replaced the BST40 original carbs on my 1991 GSX-R1100M with this. As my bike is a Canadian market bike I had to source new rubber intake boots from a MK1 Bandit 1200 which are still available through dealers. The original GSXR boots are too big, which I knew before ordering. I Installed as per instructions and after some minor adjustments they flat out rock. Good idle, clean low speed fueling, insane mid to top power gains. Worth every penny. Interestingly after I placed my order but before shipping, Fortnine contacted me to say these may not fit my bike as is. They were right, because of the intake boot situation mentioned above. I appreciate their diligence with this. I explained that I knew this and had the situation under control so they sent them out to me. As always, Fortnine rocks.

        Rated 5 out of 5 by from Best carbs My son wanted to pull my old 86 gsxr out of the garage and see if we could get it back to its glory days. The old RS36 were seized from decades of sitting. Installed a new set and the bike fired up immediately. Theses things really liven up an old bike.
