Pre-jettted carburetor for the Yamaha SR/XT/TT 500 singles. Intended for stock, or mildly modified engines. This is the carburetor only. You may need a throttle cable, and possibly an air filter depending on your setup. This will slide into the factory carb holder, but it is a tight fit. If your stock carb holder is dried out and stiff, see our related products section for a new one.

Great carb! jetting etc all spot-on for my 1980 XT500 with Supertrapp muffler. You will need to buy a different cable adjuster - preferably one at 90 degree bend but at a pinch this one will do (SKU I-M22-10-3) and you might need to trim the frame gusset above the carb for some extra room for the cable. Niche Cycle should think about selling this unit with the correct cable adjuster but its not that hard to order the correct one at the same time.

The engine specifications appear to be the same or at least very similar to the 79-81. We did not receive the SR500 here in the US after 1981, so I am not familiar with any changes that may have been made. As for physical fitment, you will need to check for sizing at the manifold, and the airbox connector if you plan to run the stock filter system. The manifold on your engine will need to accept a 43mm OD spigot. The filter side of the carb has an OD of 62mm
We don't have any experience using these specs on a DR650, but they are fairly similar engine like you say. The TM40 typically performs very well on the DR650. Could it be that you don't have it setup right? It might be getting too much fuel from the accelerator pump, which would hurt throttle response, and would decrease MPGs. You may want to disable the accelerator pump all together, and see if it improves ridability. If it does, then I would suggest ensuring that you have the smallest accelerator pump nozzle installed.
