I Ride: '09 ZX6R
Video from earlier today from a couple of the afternoon sessions. The little hill crest at the end of the straight when you go by that wall is called Alpha, or Turn 0. It is probably the most dangerous part of any track that I've been too so far. Wouldn't be so bad in a race, but at a track day, you have to worry about people coming onto the track in that same spot at a much slower speed. It is THE most critical place to really respect the blend line. There have been cases of people going like 40-50 mph crossed the blend line into oncoming traffic from over that hill and got rear ended by people going 130-140 mph.

On a different note, I think I went too much on the fork spring stiffness. Apparently going up 1 size on both made them too stiff now. Even under the hardest braking, my zip-tie was still around 25-30 mm from the bottom. I might replace just one of them and end up with 10.25 N/mm instead of the 10.5 I have now. Before, both were 10 N/mm and it felt too soft with a lot of preload on. Now I don't even have any preload on them. I just don't see how going up 1 size made such a huge difference.

Easiest way to fix that is to gain some weight
