Knocking noises; vibrations in the handlebar; oil sipping at valve lid gasket

[rdprdp01]

Good morning. We have great tuners and mechanics on the Forum. I am certain we can help you identify root causes.

Here are a couple of areas I encourage you to investigate.

Wheels which are not balanced or tires which are out-of-round or under-inflated can cause the vibration you described in your post.

Incorrect bar weights and worn suspension components can also be a contributing factor to vibrations reaching your hands on the handlebar.

Incorrect torque settings for tightened bolts (too tight or too loose) can also cause stress that can lead to vibrations.

I recall reading about a balancer backlash adjustment that may be relevant for the knocking noise. Check out this Thread and consider searching for others:

Peterbaron, pdedse, and many others are better tuners than me. I am sure they can augment or correct my post when they have some time to consider the possible causes more thoughtfully than my off the cuff reactions.

Hope this helps. David
