Through an epic battle with bearing races, my final weapon being a dremel rotary tool, I spent six hours of cutting time (probably 8-10 hours total) cutting out the bearing races!
The remover tool I purchased was completely useless, it wouldn't reach the bottom bearing race, and couldn't get enough bite on the top. I guess the only tool for it is the official Kawaski tool. However, the installation tool from Tusk worked pretty well! Worth the $120 to accomplish the installation in only about 15 or 20 minutes total, including figuring out how to use the tool.
Once I got the races in, I got to work re-assembling the front end - worked until 0130 on the 4th! Finished up the morning of the 4th with Dad's help (thanks!) and got to leave for a ride around 1230pm. We did about 110 miles and things ran pretty smooth, except for a squishy front brake - need to work on that yet.
I don't know that I'd mentioned it yet, but the replacement forks I bought came with Progressive springs already installed! Found that while changing the oil (who knows how old it might have been, so I put in fresh).
I was a bit disappointed to find that the coolant thermocouple didn't fit in the Tusk replacement radiator, so I had to rig up a switch until I can find a correctly sized thermocouple. Fortunately, if a KLR is moving more than 15-20mph, it doesn't need the fan, so it's easy to deal with just turning it on when stopped or going through slow terrain.
