WOOO HOOO! Congrats! When I still had stock internals all around I went with only two lines showing for preload in the front and only about 6mm of thread showing on the rear shock for preload. I weigh about 205lbs and ride somewhat aggressively
. The rear is too stiff stock and the front too soft. I went with .95 kg springs front and the internals kit from bitubo.
desmoworks, for fine Italian machinery Made a big difference. As far as the stuttering, go with a 14t front sprocket and all will be well. Get that slack adjusted out of the stock throttle (it is the top adjustment link by the steering head), just back it out about two or three turns and check for play. The evoluzione quick turn throttle sold by Dan Kyle (search KyleUSA), is a dream. Grip it and Rip it!
