Much of the work described under the heading of Modifications details not only what was changed but the thought processes and development progression.
The standard rear spring on the 5.7 is progressively-wound and rated 7 - 8 kg/mm. I replaced it with the softest standard Olle spring available. It is straight-would and rated 6.4 kg/mm (63N/mm).
Marzocchi Fork Transplant
The 40mm Olle forks are heavy and primitive compared to what I am used to riding. They are lightly sprung and exhibit a lot of seal stiction.
Looking at the lightweight Tech forks that come on the ePure series, they have 39mm stanchions. They also appear to have the same extra half-inch of travel exhibited by the Olles. SplatShop sells them for 882 GBP (nearly $1200 USD + shipping), so not an inexpensive upgrade. I'd also have to deal with their slightly smaller (39 vs 40mm) stanchion diameter as well.
Original Olle forks next to Marzozzhi forks shows the 17.5mm difference in length
I decided to use the Marzocchis and make up the difference in length with a simple spacer at the bottom of each fork tube where the cartridge is held in place. A longer M8 x 1.25 SHCS is also required (42.5mm versus 25mm). I achieved this by grinding 2.5mm off the length of a 45mm SHCS.

Additional Small Changes
I removed five plastic beauty covers that weighed 1.6 pounds in total (enough to offset the heavier Dunlop rear tire). Speaking of removing stuff, below is a shot of the unnecessary electrics. In addition to the original Oh-Shit! clutch switch, the map switch, mode switch box, and on/off switch have all been eliminated.
