Mk 1 carb replacement - SV650.org

Can anyone tell me what carbs are compatible with mk1?

Looking to replace mine and noticed a shed ton of 2003> carbs online

The 2003 onwards SV650 are fuel injected so they would have throttle bodies/injectors not carbs.

The 99-02 SV uses a (semi) downdraught type of carb (Mikuni BDSR39) and the only replacements I've heard of are for racing purposes, maybe someone else has experience...

The 96-99 SRAD GSXR750 uses the same carb

There are rebuild kits for the stock carbs and there are a few sets of carbs on ebay at the moment. The usual problems are stuck choke plungers, damaged screw heads (they have a JIS screw which are a bit soft) and blocked jets through being stood. The inlet rubbers can split with age causing air leaks.

Looking at the part numbers for the carb they don't appear to be shared by other bikes, though I would expect some internal parts may span models. The GSXR example above might well share things like the slide or piston valve according to Suzuki but do not expect a direct replacement of the entire mechanism.

To answer the question Keihin FCR39 and FCR41 carbs are used the SV650 though will require other modifications so are not a direct replacement, though I've not done this with either myself yet.

However the bigger questions is why do you want to replace the carbs? Are you experiencing a problem?

Thanks fellas. Replacing due to leaking fuel through one of the seals.
