Keep going the way you are, as long as the static sag is still some? The 1" may mot be valid either? No set up specs for the TTR, please do not tell me all trail bikes, are not given these basic suspension set up specs? Shop manual? If not, its on you, or someone thats been there done that, and all sorts of variables? How about a TTR hop up site? I believe you can do it! take notes, crank the spring till NORMALLY aggressive riding bottoms it out, keep the dampening in the middle if you have it. Severe and bad landing bottom outs do not count. Changes to the rear, change the front the same each time. Got to keep it even. Vintage Bob
