What is the proper idle RPM?
Wrong Idle Speed – Most cars have a proper idle speed, usually between 600 and 1000 RPMs. Idle car speed can change due to wear and tear. Fortunately, an adequate tune-up can restore the correct idle speed.
How do you adjust the idle on a Yamaha tw200?
Idle speed is adjusted via knob located on left side of float bowl; it is attached to a cable that runs under carb to a throttle stop on the right side. Knob twists by hand, crack throttle a bit to make it easier to turn. Clockwise to increase idle speed, counterclockwise to lower idle speed.
What should idle be on a Yamaha XS650?
Re-set the idle to 1200, check again, and do a final sync screw adjustment if necessary. NOTES: This should take about 30 seconds once you’ve done it a couple of times.

How to adjust the idle mixture on a motorcycle?
The idle mixture screw is only one facet of overall carburetor jetting, however it is one of the first places to start when diagnosing a poorly running bike (motorcycle) or ATV (quad). Follow the tips in this video to be on your way to being a jetting pro! Now this video shows a generalized procedure for adjusting the idle speed air/fuel mixture.
What’s the correct mix screw setting on a Yamaha?
The correct mix screw setting is exactly half-way between the two spots where the engine just begins to start running poorer. Then back the mix screw out an additional 1/8th to 1/4 turner to make sure that you are slightly rich, and not slightly lean. Running lean harms the engine.
How to adjust the CARB mixture on a Yamaha?
Set idle to an RPM that is low but still steady — about 1000 RPM if you have a smooth-running bike. Now go to the right-side carb and screw the mixture screw in in half-turn increments until the engine starts running slower. Now, turn the mix screw out in half turn increments.
