| It's not that easy - depends on your springs, oil, air gap, valve changes and any other mods you've done. Then there's the back end to worry about, before even considering your own weight and the weight distribution to take into account.
Just set it at something (like in the middle) and see how it goes for your testing, then adjust from there. Sounds simple/silly/unhelpful, but that's the only thing you can adjust on the track! |
