If the throttle on your 1994 Virago motorcycle is sticking and not retracting even after greasing the cable, there are a few steps you can take to try and resolve the issue:
Check the throttle cable routing: Ensure that the throttle cable is routed correctly and is not pinched, kinked, or caught on any part of the motorcycle's frame or components. Make sure the cable is free to move smoothly without any obstructions.
Inspect the throttle tube and housing: Remove the throttle grip and inspect the throttle tube and housing for any signs of damage, wear, or debris. Clean the throttle tube and housing thoroughly to remove any dirt, grime, or sticky residue that may be causing the throttle to stick.
Lubricate the throttle tube and housing: Apply a suitable lubricant, such as a silicone-based or graphite-based lubricant, to the inside of the throttle tube and housing. Rotate the throttle tube back and forth to distribute the lubricant evenly. This should help facilitate smoother movement and improve the throttle's retraction.
Check the return spring: Verify that the throttle assembly's return spring is properly connected and functioning. If the spring is damaged or disconnected, it may not provide sufficient tension to retract the throttle. In such cases, the spring may need to be replaced.
Seek professional assistance: If the above steps do not resolve the issue, it is advisable to consult a qualified motorcycle mechanic or technician who specializes in Yamaha or Virago motorcycles. They will have the expertise and experience to diagnose the problem accurately and perform any necessary repairs or adjustments.
Remember, it is essential to ensure proper throttle operation for your safety while riding. If the throttle is not returning to its idle position reliably, it can affect your control over the motorcycle. Therefore, addressing the sticking throttle promptly is crucial.
