Front fork oscillation under braking

[ohiorider_imp]

Someone is going to have to explain to me how rotor warpage affects suspension compliance. Cause I don’t get it. Pulsing or shimmy I get.

Popgun, sorry if my original post was confusion. Let me try to clarify. I wasn't intending to imply that rotor warp would affect suspension compliance. I meant that, after making incremental changes to the spring weight and to the Race Tech Valve, that I now have the CB1100 suspension where it is compliant for me and my weight. However, with the .80 weight fork springs, the front end may tend to want to pogo slightly under braking. It's now up to me to determine if this is because:
- rotors have spots where brake pad deposit causes brake to pulsate.
- rotor warpage.
- the fork springs are now so light that minor issues with brakes are transmitted thru suspension.
- If the fork oil is too light, which in turn doesn't control fork rebound movement as it should. That was the opinion of Matt Wiley, an 18 year tech support individual with Race Tech.
