Flipped the eccentric shock mount - wow!

This made more of a change than I was expecting. The bike is imminently flickable now without any stability issues. Enters, holds, and finishes turns much better. Very happy.

What exactly does it do to geometry that makes it so advantageous?

Did you change your front heighth at all?

Ride height: Consider your bike as just a frame and subframe hanging in space. Ride height is a measure of how high the steering head (front) and subframe (rear) are above the ground, and juggling front and rear ride heights will change your bike's geometry. Tipping the bike forward with less front ride height will reduce rake and, more importantly, trail. This will quicken your bike's steering, but reduce stability.

It's the top mount where your shock attaches. You can loosen/remove the bolt, take out the insert and flip it... put the bolt back in tighten down the shock and you have just increased your rear ride height.

How easily does the eccentric adjuster come out once you've removed the bolt?
Do you have to take weight off the shock by lifting the bike first?
Step by step instructions would be great as I want to try this mod
Cheers

The swingarm needs to be unweighted. I used a 3/8" (I think) steel rod from Home Depot & slid it though the swingarm pivot point & secured it with jack stands. With the bike on its rear stand, I lowered it onto the stands. Undo the bolt (helps to have someone lift up on the wheel to slide out the shock bolt. Reverse the eccentric cam position, reinsert bolt and voila. Whole thing took ~15 mins.
