If the front is getting twitchy, you might actually be giving it too much gas. This will put the majority of the weight distribution of the bike on the rear tire, causing the front to lose some of its traction. The optimum weight distribution for cornering is 40 % percent front and 60% rear tire. The feel of this distribution is about equal to a 5th gear roll on in the power curve of any bike greater than a 600. Any more than that when you're in the apex of a turn and you could be unloading the front tire too much, causing that twitch you are describing. Plus, the 636's front suspension is already a little jittery. You need to get to a stretch of twisties, maybe a couple S turns, low speed and high speed, without people, cops, or large, solid objects on the side of the road. Take a buddy with a car and have him watch you. Now tune and test. Play with the your throttle control, your body weight distribution *Are you putting pressure on the inside footpeg? Are you strangling your clip ons? Are you looking through the turn instead of right in front of you?* and find a suspension that works for you. The more scientific you are about the process *recording numbers, times, effects* the more benefit you will get from it. Hell, if you can get your buddy to video you, it'll be a great learning experience to critique yourself afterwards. Keith Code put out a couple great books on the physics of riding "Twist of the Wrist 1 and 2" I encourage you to check these out, because you can only fix what your doing if you know whats wrong. Most important of all, WEAR ALL YOUR GEAR! Accept the fact that you are trying to put your machine on the edge of its performance, and you might just go over that edge. Good luck and have fun!
