guys, I'm really not sure if I explained the technique properly, so I'll try again...
I never rode a dirt bike and anything with less than perfect friction coefficient asphalt scares me a lot. I'm talking about good road conditions, dry weather, on a hairpin (those tight Z curves going up or down a mountain side, like
this). I am talking about that moment between braking into the curve and going on the gas to accelerate out of it. When you brake, the weight is on the front, and when you accelerate it is on the rear wheel. That transition, that weight transference and the pitch change, is the aspect in which the C14 doesn't score very high. It is heavy, the drive train has backlash and the injection is not as refined as it could. It is easy to experience if you close and open the throttle quickly. Cable play magnifies this. It's like those SUVs that roll a lot and between curves they have to change the roll angle before tire contact patches find their grip, slip angle and so on.
Front brake has just been released and my right hand is on the gas now. So, in order to tame that weight transfer and do it less abrupt when the power finally goes from the right hand to the rear contact patch and starts shifting the attitude of the bike, I apply a bit of rear brake. That tames the way in which power goes to the rear wheel. As soon as the bike is [now smoothly] planted on the rear wheel and the rear suspension sag has been used, I release the brake. The whole thing probably happens within a second.
