I made more rubber spacers (about 11mm tall, I think) to go on top of the air cleaner after it was mounted, so it would be sandwiched and allow for vibration to be absorbed in both directions. I cut down some M6 1.0 joint connector nuts (which I had to order on eBay from Lithuania) to about 7mm tall to thread down over the rubber, until the ends of the bolts bottomed out inside of the nuts right after slightly compressing the rubber. Blue threadlocker was used to keep them from loosening.


It all fits together nicely and the new mounts I made cannot just rip apart in the center like the original design, yet they still absorb vibration just as well, if not better.


The stock air filter still fits.


Here is the air cleaner all put back together. I will have peace of mind knowing that I won't suddenly hear clunking, only to find that the air cleaner has broken loose from the engine again.
