How to Check Harley Motor Mounts in 2025

To check Harley motor mounts, simply get under the bike and inspect the mount to see if the rubber isolator is making contact with the front engine mount bracket. Signs of a bad motor mount include abnormal vibrations, jolts when changing gears, and a lack of smoothness while riding.

Another way to check mounts is to lightly load the engine while keeping the foot on the brake to see if there is excessive engine movement. Using a pry bar can also help identify separated or broken mounts. It’s important to regularly inspect and replace motor mounts as needed to ensure optimal performance and safety while riding.

Signs Of Bad Motor Mounts

One of the first signs that your engine mount is going bad is abnormal vibrations. The mount absorbs most of the vibrations caused by the combustion cycle, so without them working properly, you may feel some jittering or shaking while driving – especially when you’re idling or braking. Another indicator of bad motor mounts is when the engine jolts or thumps when changing gears or at high speeds. An engine mount that needs replacing can often cause a jolt when changing gears on an attached transmission. This jolt or thump can also be noticeable when traveling at faster speeds due to the engine working harder. If your machine doesn’t feel as smooth as usual, this can often be down to a damaged engine mount.

To check the condition of your Harley motor mounts, there are a few methods you can use. One way is to visually inspect the mounts by getting under the bike and looking at the mount. Check if the rubber isolator is contacting the engine mount bracket. You can also remove the seat and examine the mount for any signs of damage or looseness. Another method is to use a pry bar to check for separated or broken mounts. Additionally, you can put the transmission into drive and lightly load the engine while keeping your foot on the brake to check for excessive engine movement. Loose or broken mounts may need to be replaced.

Visual Inspection

When it comes to checking Harley motor mounts, visual inspection is essential. Start by removing the seat and examining the mount. Look for signs of detachment or insecurity. One of the first signs that your engine mount is going bad is abnormal vibrations.

If your machine doesn’t feel as smooth as usual, this can often be down to a damaged engine mount. A pry bar can be used to check for separated or broken mounts. Another way to check mounts is to put the transmission into drive and lightly load the engine while keeping the other foot on the brake. Excessive engine movement may indicate loose or broken mounts that need to be replaced.

Physical Inspection

To check Harley motor mounts, start by getting under the bike and inspecting the rubber isolator contact. Look for any signs of the rubber isolator contacting the front engine mount bracket. This could indicate a problem with the motor mounts. Additionally, check for excessive engine movement while the bike is running. If the engine moves excessively, it could be a sign of worn or damaged motor mounts. You may also notice abnormal vibrations while driving if the motor mounts are going bad. Another way to check for separated or broken mounts is by using a pry bar or lightly loading the engine while keeping your foot on the brake. Excessive engine movement in these tests may indicate loose or broken mounts that need to be replaced.
