Set your static sag, to your situation rather than to a generic spacer recommendation. This will take up the softer portion of the spring and put you into the stiffer coils, and it's a modification that you can reverse and reset when you get around to rebuilding.
Another thing is that these are old, narrow forks. Without the TRAC system in good working order you are going to have dive under braking, end of story. Even with the TRAC system they are going to dive more than a lot of modern forks will. It doesn't automatically indicate that the bike isn't safe, just that you need to ride with that in mind and not hammer on the brakes unless you really, really need to. -Kurt On Thu, Apr 23, 2015 at 11:25 PM, Allen Thomas <[email protected]> wrote: > If you still don't think they are dampening enough mix the ATF with > straight 30wt Dino say 50/50 mix that will stiffen things up and it is > easy/cheap to do.
