Honda Rebel makes a grinding noise when decelerating

Hey Rebel Riders, I’m in a bit of a bind here. My 2006 Honda Rebel has started making this worrying grinding noise whenever I let off the throttle. It’s like something’s rubbing or grinding especially when I’m slowing down. I’m not super mechanically inclined, so any advice or fixes would be very much appreciated.

Response

Hey there, I had a similar scare with my Rebel a while back. Turned out to be a chain tension issue. It’s a pretty common thing and not too hard to fix. Have you checked your chain and sprockets lately?

Solutions That Worked for Users:

SolutionUsers Who Found SuccessApprox. Cost (USD)Approx. Time Needed (Minutes)
Chain and Sprocket Check1$20 (if new parts needed)45-60
Braking Technique1$0Immediate (practice required)
Chain Tension1$020-30

Symptoms:

  • Grinding or rubbing noise during deceleration
  • Noise more noticeable at lower speeds
  • Sound seems to originate from the chain or rear wheel area

Possible Causes:

  • Loose or overly tight chain
  • Worn out sprockets
  • Inadequate braking technique causing undue stress on the drivetrain
  • Lack of chain lubrication or maintenance

Solutions That Worked:

  1. Chain and Sprocket Check
    • What I Did: Inspected and adjusted the chain and sprockets for wear and proper tension.
    • Outcome: Replacing a worn sprocket and adjusting the chain tension resolved the grinding noise.
    • Personal Experience: I noticed significant wear on the sprockets and the chain was quite loose. After replacing the sprockets and adjusting the chain, the bike ran smoothly without any grinding noise.
    • Estimated Cost: $20 (if new parts needed)
    • Time Needed: 45-60 minutes
    • Detailed Steps:
      1. Place the bike on a stand to elevate the rear wheel.
      2. Inspect the chain for looseness and the sprockets for signs of wear.
      3. Use a chain tension gauge to measure the chain slack, adjusting it to the manufacturer’s recommended specifications.
      4. If the sprockets are worn, remove and replace them, ensuring they are properly aligned.
      5. Test ride the bike to ensure the noise is resolved.
    • Handy Tips: Regularly clean and lubricate the chain to extend its life. Always use the correct tools for sprocket replacement.
    • Expert Tip: When replacing sprockets, it’s often a good idea to replace the chain as well to ensure even wear and optimal performance.
  2. Braking Technique
    • What I Did: Improved my braking technique to balance engine braking with active braking.
    • Outcome: The adjustment in braking technique led to smoother deceleration and eliminated the grinding noise.
    • Personal Experience: I realized I was relying too much on the clutch and brakes, which put extra strain on the drivetrain. By adjusting my technique, the noise disappeared.
    • Estimated Cost: $0
    • Time Needed: Immediate (practice required)
    • Detailed Steps:
      1. Practice gradual deceleration using engine braking before applying the brakes.
      2. Adjust the timing of clutch engagement to avoid abrupt deceleration.
      3. Practice in a safe area to get a feel for smoother braking.
    • Handy Tips: Pay attention to how your bike responds during different braking techniques. Adjust your style accordingly for a smoother ride.
    • Expert Tip: Proper braking technique not only prevents mechanical issues but also enhances riding safety and control.
  3. Chain Tension
    • What I Did: Checked and adjusted the chain tension to the correct specifications.
    • Outcome: Proper chain tension eliminated the grinding noise.
    • Personal Experience: After adjusting the chain to have the correct amount of slack, the grinding noise during deceleration stopped.
    • Estimated Cost: $0
    • Time Needed: 20-30 minutes
    • Detailed Steps:
      1. Measure the chain slack at the midpoint between the sprockets.
      2. Adjust the chain tensioners on either side of the rear wheel to achieve the recommended slack.
      3. Ensure the rear wheel remains aligned during the adjustment.
      4. Re-check the chain tension and wheel alignment after a test ride.
    • Handy Tips: Always check the chain tension in multiple spots to ensure even tension throughout.
    • Expert Tip: A well-maintained chain not only reduces noise but also improves overall drivetrain efficiency.
