I run one also ,and have the same bike , the Kouba CRF4 (1.75in) , works great , and Norm is a great guy (they make them near where i live) and if you have any issues , you can call him and he will help you with any setup issues/questions
I run my forks 6mm up in the clamps and it works fine , the only thing you have to get used to is the sag will be way different , instead of 100mm like normal it will be around 80mm
You can see how far the forks are up in the clamps
