  1. I'll be down to NOLA as soon as possible. Bit busy this summer though. I have big changes in my life I'm about to make so budgets are being adjusted accordingly. And yeah $500 is steep, but it's just money and there is always another client with an emergency that'll pay what I charge to fix it.
  2. The RideSmart event was nearly flawless. Hopefully this will lead to COTA unclinching their sphincter and allow other orgs to hold amatuer events like this. We'll find out soon. I've ridden Mid Ohio, Barber, Oak Hill, Motorsports Ranch and Eagles Canyon. I've also been to Mugello. As a facility COTA is in a league of its own, 4 star all the way. I'll be taking the family to an event there as soon as I see something worth the drive down. The track layout compared to the tracks I've riden is really different. I couldnt make it flow for me and I never got comfortable or went 'fast'. Turn
  3. All good points about the reasons not to go to COTA. RideSmart charged me $500+ a day for the opportunity and I bought both days without hesitation. They sold out the entire allotment in 30 minutes. I would have happily paid $1000 a day for CSS instruction and track day and CSS would probably have sold out in 20 minutes. How often do you get the opportunity to ride on a track like COTA? Also consider all the drama that followed after w/ the dooshbags canceling all events that didn't have deposits already paid. I recently received the email from COTA about the $50K/day track renta
  4. I searched and didn't see anything so I had to ask: when?????? I get to ride COTA the first weekend of June with RideSmart so I'm really looking forward to that. But I'd love to get to work with Keith and crew again. Based on what I've seen COTA would be a great place to teach. Maybe 2014?
  5. Well - turns out that the left fork had developed a small leak that I somehow missed! So all of this worry was...not entirely a waste: I did learn some new skills. Anyway - bike has been in the shop getting all the suspension stuff freshened up. We are also going to raise the bike a bike to see if that helps me. The Duc is set up much taller than the zx6 and I really like how it handles. Hopefully all of this will get me back to my happy place so I can get on with the getting the knee down.
  6. Had an off in 2010 so had to lay low w/ the wife and kids for a bit then business got busy....life happened. The upside - I'm back. Turns out 99% of the problem is that one of the forks had developed a small leak which I had not noticed. So the ZX6 is having the suspension redone. Should have it back Tuesday (3/27). In the mean time I'm back from a 4 day break in Northwest Arkansas where me and my new Duc spent some quality time in the hills. I've gotten to know her much better. If business keeps going well I'd like to get another 848 to dedicate to the track.
  7. To me this is all about where you are looking. The whole way through. As I'm warming up I'll come up on corners and get excited so I brake too much because I think I'm going to fast. Then I'm too slow and have to add more throttle, but by then the good stuff is already over. Later in the day when I'm warmed up and I'm working right I'll approach those same corners much faster and get mildly uncomfortable, but instead of over breaking I tend to shift my vision further down (in) to the corner and find that my entrance speed is about right. I might trail out the brakes a hair longer, but t
  8. Had one occation that really should have been videod and posted: End of a great track day. I mean spectacular. We're loading up trucks and my friend borrows my ramp. I made it myself and being somewhat paranoid it is pretty wide. My friend tosses it up on his truck and gets ready to load his bike. While getting ready he comments about how wide the ramp is, jumps on his bike and says "watch this". He didnt really have the speed and about half way up the ramp his courage fails him. fump! He bailed off the bike and the bike bailed off the ramp. No injuries, just a good story to tell.
  9. Funny you mention this. I've had friends and co-workers ask me to teach them. Given my relationship with gravity I always teach them by directing them elsewhere. I'd prefer not to provide too much fodder for these videos.
  10. This stinks... I'm all setup to go to the track tomorrow but the temps are going to be in the 40s (F). Last week they had forecasted 60s. Oh well. Looking forward to getting back to this: and this:
  11. Turns out that using the stands wasnt as brilliant as I thought. The front stand is lower than the rear stand so the bike was leaning forward adding weight to the front. Lesson learned. So now I get to do it all over again.
  12. Just did the front suspension today - zoinks! The bike was previously setup perfectly for me. Or at least I was really comfortable riding it and had the confidence to ride it at my ability level. Now...not even close. Under breaking the front end feels like it is all over the place and then once I lean the bike over it felt like the back end was trying to slide out. I basically backed all the way off b/c I wasnt comfortable. Difference - I've put on 10lbs - joys of being a hot shot software developer. Anyway - I took the measurements. Unfortunately I didnt have a metric tape s
  13. I've searched and not seen an answer to this yet so... I need to resetup my ZX6. Don't have anyone around to help me. I do have stands though. Rear stand and both a stem stand and a fork stand. Can I use these to do the sage settings? I would assume the stem stand along with the rear stand will let me measure the fork extension. Then the fork stand will let me get the static sag and sag with me on the bike using a zip tie to measure the travel. Not sure how to do the rear though. i need a way to raise the bike until the rear tire starts to lift, get that measurement and the u
  14. Thanks. The tires on now are going to be pulled off anyway. I hate wasting anything but the mental aspect of not being confident in my tire makes buying another set worth the investment. The other set will go on and we'll see how they do.
  15. I have two sets of pirelli diablo rosso corsas mounted on wheels. Both were purchased in July of 2010. One set was used until August '10 for about 2 or 3 days. I then took some time off and started back in July of 2011 but only managed 2 or 3 more track days. The tires appear fine and have tons of rubber left. The other set has just sat in the garage the whole time and not been used. My question is this: does it matter that the tires are over a year old? Does that affect grip? I'm fine with tossing the used tires. But are the 'new' tires ok?
  16. Cool. Is that a book and is it still available? I've Mr. Trevott's book "Sportbike Suspension Tuning" and a few various posts around the internet. I'll probably start putting theory to practice this week as I get my ZX6's suspension set back to where it should be (it's the poor victim of my stupidity). I've also heard that Traxxion has a good DVD that I'll order. However, it's kinda like learning karate by reading a book - it just doesnt quite work. Having an experienced master showing you how and then watching you do it while providing feedback can be worth reading an entire li
  17. Do you have an open pitlane policy over there then? We have the odd day like that here, but Novices are told to stay away. Generally though the format is 3 groups, novices, intermediates and the fast group, each getting 20 minutes of the hour. That way you don't tend to get such massive speed differentials and by the time you get into the fast group, your lines are good and even if you're getting blitzed by the racers sneaking in some practice, you'll be confident enough to deal with it. It was a member day so the groups are cars, bikes and karts. We don't usually have a problem with c
  18. Tweek I'm not sure I understand this. Is he ahead at corner entry? Gus Depends - I was entering turn 1 when he was entering turn 3. I closed the gap and demonstrated what happens when a front tire touches a back tire (among other things, target fixate much?) between turn 3 and 4. I didnt seem him enter the turn so had no idea he was on the other side or what his speed was. Completely my fault and the point I'm trying to make - Get an idea of what the slowest pace on track is for the day and be on the look out. Usually I'll spend a few laps trailing the slowest rider to see what l
  19. Funny - I was going to offer up trail braking. But that appears to have been well addressed. Personally I think that CSS through the 4 levels covers everything needed except for one thing it cant really cover: experience. After doing any of the levels or all of them you have to get out and just do it. One thing I will mention - as you practice you will get faster. Be mindful of this because you'll go from being the guy that provides passing practice for the racers to suddenly having to get around other riders and making the racers passing practice more 'real'. Then one day some %^#
  20. I'm not certain that you have to be at 45 degrees in order to pull 1G. I know that I can get the bike to 45 degrees going pretty slowly and not pulling anywhere near 1G. I do it all the time on turn 11 going in to the pits. Just one last knee drag to say good bye. I wonder: given a really huge skid pad, say 5 miles in radius, if you went really fast, pretend we're on a light cycle, but were turning in an arc that was really wide if you could go fast enough to pull 1G with only 15 degrees of lean angle.
  21. We'll see. Most of the CSS coaches could probably easily qualify midpack of an AMA superbike race. I'm sure I'll be real entertaining. But....I just cut 2 seconds off my best time around ECR (2:10 now - lap record is 1:45 & front CMRA racers are in the high 1:50s). Building off of the 'Drive Plan' from soft science, I've changed the way I enter several of the turn by taking a wider entrance. I use less lean angle and carry more speed and the engine stays right in its sweet spot to blast back out. Not as much knee dragging, but easily several seconds faster without doing anything '
  22. I've never noticed that it takes that much effort to turn the bike. It isnt a brute force afair. In fact I'd say that if you try to brute force the bike it will toss you on your butt for the trouble. After a really good track day its my brain and thighs that are tired. My wrists are usually sore too because I use them too much to hold myself up under braking (having one pinned and glued together doesnt help). But the big deal is the brain, after a full day of riding (usually get 6 30 minutes sessions) in 90+ heat, I'm more zombie than human. Luckily the trailer is easy to load, the drive
  23. I'm not really too concerned with how much effort I have to put in to turning the bike. Good body position puts you in position so that you are pushing perpendicular to the bars so all the effort acts to turn the wheel. If you are still on the brakes when you start your turn then absolutely it will require a little more strength which makes perfect sense: At that point in time there is more weight on the front tire than the back. You'll also perceive more weight because you are having to hold yourself up against the forces trying to send you over the handle bars. Good fun. To address t
  24. I skimmed through a lot of this discussion and didnt notice anybody mention the suspension's affect on the radius of your turn. If you roll on the throttle the forks changes the bikes geometry. Longer forks tubes mean slower turning for a given lean angle. Conversly the brakes compress the front increasing the rate at which the bike turns for a given lean angle. All of which comes together somehow to explain what Keith is trying to teach us. For instance, on the way in to a turn you are deaccelerating so the forks are compressed helping you tighten the line without adding lean angle.
