So the key is in the gas???

So if you want to go fast, you gotta use the gas.
If you want to lower your lap times, leave the gas open longer.
If your not on the brakes, your on the gas.
If the rear slides, you need to stay in the gas.
If the front slides, you need to stay on the gas to move weight to the rear.
To get a good drive out of a corner, get on the gas sooner.
When you enter the corner, get on the gas to stabilize or load the chassis.

Drucker always tells me to "pin it." Everywhere. Just "Pin It."

So I guess I'm just going to need better gas.......

If you look at telemetry data from cars and bikes on the track, the fastest drivers/riders throttle graphs look like stairs, damn near on/off. That's not to say that aren't superhumanly smooth on the inputs, but there is no on/off/on/off the gas in the corners. They know exactly when to shutdown and exactly when to apply WOT throttle.

I saw something comparing Mladin's throttle input during a race to other rides and he spent a few more percentage of time (like 3%) at 100% throttle than the rest of the field, and he won. Go figure.

I find this interesting, since i find myself in a scary, yet saveable, front tire slide about once every track day.

The events leading up to this usually go as follows:

Begin trackday, get comfortable with the track and the line, work the bike up to speed.
Realize im carrying good cornerspeed everywhere but corner x.
attempt to brake a little less on the entry.... still to slow...
repeat until im frustrated with myself.

On the next attempt, forcibly remove my fingers from the brake lever way, way too early.

Shrug off the 'shit im going way to fast now' feeling, and throw the bike at the apex.

The front starts to slide. immediately i un-countersteer (to get more contact patch on the front) which of course makes me run wide. I make the corner, usually with a few inches to spare of running off the outside.
This whole 'saving the bike process' is a automated response. Honestly i dunno what i do with the throttle. I think i just keep it in maintenance position until its all over.

Then i change my underwear.

It seems to me if i opened up the throttle i would run more wide and off the track.
should i leave the steering alone and just use more gas?

Usually front end slides the front tire turns in toward the turn what should happen is knee down applying pressure ',gas on a little more than maintence throttle this is usually enough sometimes alittle picking up of the bike with body leaning more inside combined with above works too.Sometimes nothing works at all daaaannnngggggit.

A related truism is: you aren't riding when you aren't on the bike.

Actually..... giving up on the brake completely is causing your trouble.

When you take your hand off the brake it UNLOADS the front end and
reduces fron grip as you are adding speed which needs MORE grip.
THis is heading to a front end slide

At the end of the braking zone fade the brakes to about 2% - 5 % and
keep them on until you are happy with your direction change. Then, transition to maintenance throttle for mid corner, then stand up and drive off.


Amazing how much more grip a loaded tire offers.

Yet it's just as amazing how quickly a slightly over loaded tire loses grip.
cough cough, Putnam turn 4......

Such a fine line. It's sucks when you end up draggin both knees in the corner, then your ass, then your back, then your head......

Now greg, I'm not going to be there this weekend so maybe you will brake your crashing theme that you are getting into. Just remember to listen to your tires, and when in doubt get some new rubber on the way by.

or an overloaded footpeg (on the asphalt) leads to underloading/unweighting your rear tire
