I wasn't happy with the way my ZX6 was tipping into corners. Went to my local bike shop and spoke to a few of the fellows there. One suggested I changed to a 65 profile front, another said to drop the forks through a bit, and the mechanic who also happens to race suggested I put some spacers in my rear shock.
I stuck 2 in, and raised the back about 4 or 5mm. Went for a ride on the weekend and the bike feels %300 better! The front's not quite as stable as it used to be, but the bike holds much better lines now.
All I need is a new front tyre and some decent warm weather to give it a proper test.
I'd recommend this upgrade to anyone. And if anyone's interested, I can do a report and stick it up with the next update. (Which I'm still working on. Been a bit busy.)
