I've heard people complain about wearing through woodcraft pucks in a day, I've read magazine articles that claim they last forever, It's all a matter of how you as a rider use the knee puck,
The OEM sliders on my Dainese suit have lasted me at least 50 track days, and I JUST flipped them to start wearing them the other direction, so probably another years worth of use before I replace them. I touch my knee down a lot, but I rarely drag or grind it into the pavement, just light pressure and let it skim along, or a slight reach out to kiss the pavement to confirm my lean angle

Sometimes we hear a rider using one pressure for the street (substantially higher) and another for the track. I don't quite get that. Well, I do, but I wouldn't personally do it. Unless riding with a passenger, or otherwise heavily loaded.
It's entirely possible that running track pressures while street riding could result in improper wear on your tires and cupping, you don't exactly do a lot of miles bolt upright on the track so the tire wear pattern's would be considerably different.
I also think Cobie would give me a stern talking too if he saw my used tires when I pull them off my commuter bike

I've had a few cups from the Water Cooler Labeled Skratch when I was extremely parched following some spirited lunch sessions, it seemed to work pretty good.

At a CSS school day you should be riding below your limit and working on drills and techniques, its not the place to set a fast time, and due to the mix of riders on track odd's are you'll never get a good clean traffic free lap if your going to try and set a personal best time anyway. If you show up for a lvl 4 school and say you just wanna set some fast lap times, I'm fairly sure they will refer you to the CODE Race school for that. For that reason its rather difficult to compare lap times from a CSS school to anything else.
That said, I believe the data in this thread is a little outdated, the most recent record I can find is Jeremy Toye on a CRB1000RR @ 1:14.271,
IMO the CSS chicanes track configuration add's about 2-3 seconds to your lap time. Your Results May Vary

I'm not 100% familiar with the WSBK rules, but I'm gonna say the H2 and H2R wont be allowed because they are supercharged, I also don't really think it's going to make the best track weapon out there, but it will definitely change the game at the drag strips for stock classes

Your right on that Spaghetti,
Lower pressure = More Carcass Deformation and Flex = more heat, adjusting your pressures can help compensate for extreme weather conditions, lower pressure when its cold for more heat generation , higher pressure when its hot for less,
you also run lower pressure at the track for the larger contact patch that is generated by the additional deformation of the tire at lean

the new KTM production MotoGP bike would be awfully fun to ride around Laguna Seca for 8 hours, Assuming the noise monitoring station isn't listening,

Someone posted pic's of the Attack Kawasaki CRT bike a few years back and all the DAQ stuff it had, it included 3 IR temp sensors on the rear tire, each side and the middle. I'm going to guess the most effective use of that kind of information is really tire compound choice and pressure, you're not going to really look at the tire temp mid lap and adjust your pace, but after a practice session you can review the data and adjust the pressure or compound your running based on the recorded data.
If you happen to have a DAQ system with open Analog or Digital inputs, you can probably add that functionality for considerably less than the cost of that system, although it might not be as sleek and pretty a addition to your cockpit

honestly I've found I'm more likely to shift into neutral by mistake clutch-less than with the clutch
On a 600 and a tight track, 2nd is pretty much a necessity, and while I wont use 1st all that much I do occasionally use it coming out of the chicane at Streets, if I'm behind rather slow traffic, or trying to pass a student on one of the school's bikes that likes straight line speed

I'd be good with this really

I do enjoy waving to riders as I pass them on the freeway with my right hand

yeah, but its not 300 Hp .....

I have read at 155mph we are traveling faster than we can actually process information (hence the 155 limiters on many European cars).
I'm not sure I believe that, for one I have defiantly met people who were unable to process information traveling at 25 mph, and pilots seem perfectly capable of processing information at considerably faster speeds than 155, so I don't think the actual speed has anything to do with it. I think you just have to adjust your frame of reference depending on the speed, for example a 3 second following distance varies from 220 feet at 50 Mph to 660 feet at 150.
I would agree that at those kinds of speed we are unable to process all the superfluous information around us, which could help enable the zen like focus that you describe

I can attest to having real cruise control on a motorcycle as supper awesome !!! but cornering at perfectly flat cruise control regulated throttle is a bit unnatural feeling if you're used to using proper throttle technique in corners.
-
I'd be interested in a sensor that would let me know what the bikes physical and effective lean angles were so I could quantify the effectiveness of my body position in a particular corner

Not to mention the manpower required to put on and remove warmers from a fleet of 20-30 bikes , and the need for the additional sets of stands for every bike, that's a logistical nightmare
-
That's a pretty sweet video, but like KTK said its not quite as hard as you would initially think, I'd bet money any one of the schools coaches could do the same thing, they regularly reach out and drag fingers along the curbing and track edges for the "Reference Points" drill

Hey welcome to the forums,
Your friends advice is probably spot on, and I'm sure your going to have a great time doing levels 1 + 2 in October. The weather here in California has been a bit hotter than usual, so its hard to guess exactly what the weather will be like out there, but normally October is pretty nice reasonable weather out at the track. Though I'm betting your probably well acclimated to the heat living that close to the equator.
What is the traffic and road conditions like where you live ? Everything I can recall seeing on TV that involved driving in that part of the world looked a bit on the hectic side, I'd venture to guess its a dangerous place to be a motorcyclist ?

Really great stuff man, awesome to see you back at it so soon after your injury !!!

Everyone always say's the new guy is doing it wrong, up until he starts winning

the gauge at the top will unscrew from the hose, you can totally replace it with any brand of pressure gauge, should just be standard 1/4 NPT Threads, if you want the gauge REALLY checked out, you could just mail it too me and I can test it at work
-
send me a picture of it
-
What kind of gauge do you have ? If it has a removable pressure gauge you can simply buy a high accuracy gauge from a manufacturer like Ashcroft or U.S.G. and replace it,
For example you can get a Dwyer DPGA-07, 50 PSI Digital Gauge, 1% F.S. Accuracy ( +/- 0.5 PSI ) and 0.02 PSI Resolution for about 65$.
That's better accuracy and 5x the resolution of the Motion pro gauge

I get 10 track days and another 8000 freeway miles out of a Q3 front tire, It's hard to beat those kind of numbers
