1. Set the Zero Point - While viewing the file on the Bottoming Screen go to the “Set Zero Point” section, select “Manual Zero” and click on the “Zero” button.
2. To keep this “Offset” for future recordings, particularly for Street and Road Race bikes go to Edit, Preferences, Select your Vehicle Type (or set one up), and select Setup. Go to the “Rear Settings” (or “Front Settings”) section, uncheck the “Smart Zero?” box and input the “Manual Offset”. Using “Manual Zero” is particularly good for pavement use where the suspension may not get to full extension on each run. This “Manual Offset” should be good until you move the transducer mounting.
3. To calculate Sag, go to the “Waveform Analysis” screen, select “Dual Cursors”. Find the point where you pushed the suspension down, let it up, and it stopped. Drag the “In Cursor” (green) to this point.
4. Out Cursor - Next, find the point where you pulled the suspension up, let it down, and it stopped. Place the “Out Cursor” (red) at this point. Half way between these two travel numbers is the Sag. Read Sag from the field marked “Avg of in point and out point”.
5. Stiction Zone - The difference between the travel at the “In Cursor” and the “Out Cursor” is caused by friction (or stiction). Read the “Stiction Zone” from the field marked “Diff”. The greater this number, the stickier the suspension is. 6. Free Sag - Repeat this procedure with the Free Sag portion of the recording. Note: Free Sag means nothing unless Static Sag is set correctly. - Notice the Diff (Stiction Zone) is about the same for Sag and Free Sag (6.99 vs. 4.11). This is as it should be. If it is much different the suspension could have more friction at different points in the travel or your procedure of pushing up and down might not be consistent.
8. See 7.4 Sag Guidelines. If your numbers are off from these adjust the spring preload.
9. Save the numbers - Input this data in Notes, Clicker Settings. |
