Front End Klunk

After reading about the problem on this site, it got increasingly annoying as I went over bumps.
I ordered a pair of Top Hats and changed the Fork Oil to a 20wt Synthetic (not Yamaha because I hear it tends to foam).

The Klunk is gone. Thanks to all who contributed comments to this topic.

I considered changing to progressive springs.
Since I almost always ride solo I decided to stay with the stock springs.

The ride is a bit more firm with the heavier oil - pleasantly so.
