Robert,
regardless of the fact that the qoute was posted somewhat out of context time wise the bikes definitely had a problem at Las Vegas. Three of twelve contests were not decided by the tree over the first two round and you can't put that many down to bad riders. As mentioned in another reply there appeared to be something awry at The Strip as regards the bikes. I spent quite a while with Jeff Foster in the tower at Indy early one morning during the Nats and learned just how delicate the situation is with the bikes regarding timing.
On the reaction time 'tron is right about the quicker reaction of the hand re the foot. It is a lot easier to unclench a fist than move your leg. Fuel cars are a totally different situation but pro stock cars have a lot more options in the area of air gap, pedal geometry etc to avoid red lighting versus the bikes.
As long as some of these riders have been doing this do you not think that they should be a little more consistent. The fact remains that it does not take a guess to bulb on a bike,

I didn't say wait for green, I mean wait longer on yellow, if leaving as soon as it turns on is too soon.

Now that is an interesting concept. How would you propose the driver do that? If anything the LEDs have eliminated any chance of changing the driving style. The old bulbs, if you were dialed to the tree, you could see the filiment getting brighter and then dimming but now you can't. So it has to be done mechanically.
I thought that was a pretty good suggestion about the hydrulic clutch and the tuneability. Sounds a lot like adjusting the cannon on a Nitro clutch.

Why not just have the yellow and green come on at the same time for PSB? Take a poll. If the majority of the riders wanted it, give it to them. I realize this is probably way too simple and effective for NHRA.

It's not the LEDs, the PSBs are guessing when the light comes on, if they would quit doing that there wouldn't be hardly any redlights.

That's a joke, right?
I have not looked at the data, but I am guessing that most of the bulbs are between -.010 and -.030, is that reasonably accurate? If so, how could anyone guess within 10 or 30 hundredths of a second when the starter is going to flip the switch, also taking into account the random delay between the switch and the tree. if the lights were -.200, or before the tree was activated, I would buy the "guessing" theory. As is, no way.

Look at the race results over the season, it's clear that the problem is more about gambling than set-up. The vast majority of the red bulbs are by covered bikes.

Hey Tim, you better look at the stats from Vegas before you say no way.

I agree Keith that they have a problem. So have I. So have you. What do we do? We fix it.
I don't expect the rider to try and adjust. That would be a poor solution. They need to quit whining and fix the problem. Somebody out there knows how to do that.

Vegas results...Avg. 'bad' bulb .051. 10 out of 11 redlights were by the slower bike. I'd offer Angelle/Stoffer and the Tonglet/Gann race were more legitimate bulbs. The reality that the bikes react quicker and, hand-eye coordination is faster than foot-eye, an .030 red bulb is a LOT worse (more of a gamble) on a bike than in a car.

Man there is alot of ignorance being expressed in this thread...................I also have a feeling that if the quote came from Andrew Hines, it would be concieved as valid instead of whining. Roo, Dunlap and a few others offer constructive solutions to the problem. others offer what????????
There is a problem with the bikes, it has effected the whole class this season, not just the Army camp..................
Personally, I think that there has to ba a solution right on the handlebars, with the fulcrum point of the clutch lever. Or perhaps run the cable through adjustable pulleys that can be tuned. I would think that someone smarter than me could come up with a way to tune the clutch lever.....................

here we go again. please somebody call in the wambulance. when nhra went to the led set up a lot of people were going red , including myself. after a couple of red lights i got out my 1/2 inch wrench and moved the pivot point on the clutch linkage one hole back making the travel farther on the pedal and SHAZAMM! the red lights went from .390 to .430-.450 green. and i didn't even break a sweat.

Screw it...this could go on and on for 500 posts, just like before.
Just go back to what was said on post #7, replace them with pro mods.
The only 2 reasons the stands are even half full when they run anyways is becasue #1 the people want to have a good seat for when the fuel cars run, and #2 Harley fans.

Lance, you're repeating what I already posted.
