  1. Wet Vs Dry riding

    I'm planning to ride dirtbikes with my son today so I can sample some of the reduced traction you speak about. Ciao! (please keep the thread going)
  2. Wet Vs Dry riding

    Inspired by the mystery of what to do and not do that is involved in wet riding, I thought I'd start a collaborative list of differences and limitations in riding in the two environments. To start what we know: You cannot Quick Turn the same You cannot brake as hard You cannot accelerate as hard mid-corner Anything else?
  3. Wet Vs Dry riding

    Great list and write-up! Wrote any good books lately? (LoL) I'm very much interested in asking about #3 above. I recently reviewed the chapters on steering in TOTW2 and had not before paid as much attention to one of the drawings comparing lines. In one drawing the rider made a smooth arc through the corner but in the other, the rider made a sharp hook at the steering input and it seemed as if Keith was advocating the hook. I'd think that a rain rider might also prefer a hook as they are on the side of the tire less. If this is the case, why use the far side of the track for entry since it will put you in the same place anyhow with "midcorner" being a geometric line (instead of a curve)?
  4. Crash test dummy

    Yep, can't wait (LOLOLOL)
  5. What happened- My Highside Crash

    I will study it with vigor!
  6. What happened- My Highside Crash

    I'm looking for clues, analyses and helpful information. I am not hurt and the bike (hopefully) can be rideable again in short order using a few bolts and copious quantity of duct tape to get me through the remainder of the year, then I'll properly rebuild over the winter. I should also make it known that the crash sequence has been edited and isn't gory or graphic. The raw footage wasn't gory either, but I edited it to purposely take some of the potentially emotional impact away from viewers, so we can focus on forensics.
  7. What happened- My Highside Crash

    I think my answer is in Ch 13 TOTW-2. Recently I attended Cornerspeed and one of the takeaways that restates the sentiment in Ch13 is to think of the motorcycle not as a bicycle with an engine but think of it as a unicycle with an engine. For me this means that I asked too much of the rear on a compromised surface. It's the only logical choice.
  8. Leaning on straight

    Not only am I also looking at that chapter I'm also looking at the subsequent chapters with a fresh perspective.
  9. Another SAG question...

    My stab at it is that Keith works with so many riders and so many bikes that giving a percentage is more workable than giving numbers due to the range of available travel on different models of bikes. You could always do the reverse math and would derive to the same. SAG numbers aren't set it stone, but they give you a starting point to work from with other adjustments and you actually may end up changing preload settings while tuning, which is what Dave Moss did with my bike- he checked sag first (I initially had no free sag making the rear too stiff) and after a couple sessions on track, preload was taken out by a few turns in the front. Although you'd want to be precise in your measurement of sag it's still a ballpark figure based on percentage range of travel, which is what the manufacturers provide- a range.
  10. What happened- My Highside Crash

    Many of the people I've asked to review the video have said that it's a greedy right hand causing the crash. I'm not convinced this is the case here. And here's why: The video doesn't show the moment the rear end comes around thereby ejecting me from the bike. It's difficult to ascertain if the rise in RPM came from my throttle hand or the loss of traction allowed the engine to spin more freely, thereby causing the rise in RPM but I believe the latter. This bike doesn't have data log capability, otherwise it would be easy to download the data and look at TPS log. and compare with RPM log. Turn 14 has a very slight rise to it, which SHOULD have contributed to improved traction and I wasn't in the standing water in the curbing. From the video is looks like the turning had been completed and attention was on the exit phase when a roll-on would have been appropriate. It is during the roll-on that there was a sudden and marked change in RPM and I believe that I held the throttle steady during the sequence with the hope that traction would return same as other slides experienced (okay, okay, I admit...my hand and arm was frozen like a butterball turkey on November 20th when the rear came around and when I realized, my mind was then commanding: "Relax"). From viewing footage of other prior turns, it doesn't indicate a habitual abuser of the throttle. That's my case and I'm seriously looking for answers, I know this is the rider's fault, IT'S ALWAYS THE RIDER'S FAULT. And this rider is looking to make corrections.
  11. What happened- My Highside Crash

    What I know sofar: The limit of rear traction was exceeded and continued to be exceeded throughout the crash sequence. I'd experienced a lot of little slides in various places around the track. Traction seemed to be better when the rain was steady and harder than it was with the light precipitation. In many of the curbings, including this final turn there was standing water. Professional races are not conducted when there is standing water on the track surface, which means that perhaps discretion was better than valor this day? What the video doesn't show: The rear end coming around before I was ejected What is yet unknown Was the throttle rolled on to make RPM go from 6500-8000 or was it the loss of traction?
  12. Where can I get Heavy Duty Hangars to hang my leathers? I thought I had a good one until it snapped in half this weekend.
  13. Crash test dummy

    I just posted a video clip of my crash and I've got no permanent bodily injury. My finger tips feel a little singed but that's about it. I got zapped on my elbow by the hook on my trailer packing up (go figure).
  14. Hangars for Leathers

    Thank you. While I wrap my mind around spending so much on hangars, I happened to stop in Cycle Gear and the guy there was happy to give me as many as I wanted. I took 4 home.
  15. What happened- My Highside Crash

    @Playersnoopy- I don't know if we've met but I'm open to it if we haven't. I'm going BACK to NJMP on 28-29th if that matters to you. From my recollection and from what I can ascertain from the video the RPM rise occurred when the tire broke loose. I felt the rear end come around and I intended to hold steady throttle, but when I got launched, all control had been lost. I've let others view the video and they've said it's a greedy right hand that caused the break in traction. Although I'd been working on improving my exit drive I'm an extra cautious guy...heck I might post a dry video just to show how "genteel" I usually get on the gas.
  16. I heart level 4

    Wow!!!! Congratulations to you AND your coach!
  17. That’s pretty cool. I’ll have to watch that again later!
  18. How did YOUR weekend go?

    I just bought a dirt bike and I didn’t believe it before but it’s same same! I’ll be riding that A LOT over the winter, etc.
  19. This past weekend, my bride and I took our new enclosed trailer on its maiden voyage to Virginia International Raceway to participate in a trackday with Aaron Stevenson's Cornerspeed riding school. I've wanted to do his school for about as long as I've wanted to do CSS- just that I committed to CSS first. To add to my sense of urgency, Dave Moss was scheduled to be there and since I had already been watching his videos, etc and corresponding with him about a problem with the forks I'd upgraded I decided HECK YEAH! Little did I know that an additional bonus would be that Tom Kipp would be there. I didn't know much about him, so after I got home I looked into his racing career to discover that he has 4 AMA Supersport crowns on his resume; he's now retired from racing and according to what I read is now a preacher. During one of the classroom sessions, Tom offered to tow me around the circuit. Unfortunately we got separated by Tom getting around a slower rider and it took me a bit longer to catch up...and then he turned up the pace a little...a little too soon for me as I didn't have enough attention for my RPs and watching Tom's lines. I also had an opportunity to ride 2-up on the back of Aaron's prepped GSXR with a passenger hold on the tank. THAT was a HOOT! I haven't been on the back of a motorcycle since I was 5 and I'm a long ways from 5 years old. We took off and Aaron immediately pulls a power wheelie from pit road getting onto the front straight to join T1. What's notable for me was that I could really feel each time when the front wheel wasn't in contact with the pavement and also when he set it back down and it wasn't in-line with our direction of travel. Aaron was braking in places where I could only dream of doing the same. He knows ViR very intimately. One of the hallmarks of his teaching is NO COASTING. He believes in either being on the gas (hard) or on the brakes (hard) and it shows in the time it took us to get around the circuit 3 times. On the 2nd lap I thought my arms were give out from braking into T1. I got through the agreed 3 laps then tapped out from the flood of emotion and kinesthetic overload. I've got the video I took on my Sena 10C, but I'll have to review it first and see if I can remove the swear words before I post it. Did I mention that I got Dave to tweak my knobs!!!? I generally don't like people tweaking my knobs, it's rude and uncivilized but in Dave's case not only did I LET him, I PAID HIM to do it and couldn't give up the money fast enough. He gave me a few things to feel for NEXT WEEKEND when I head to NJMP Lightning (smile). Lastly, I'd like to say that I hope I don't take as much time between CSS and my next trackday EVER AGAIN. I was last at CSS in May @ ViR and I found it a steep hill to climb. I think my visual skills are much better and I like that. I still need to work on my ability to get the bike steered, into and out of the corners faster.
  20. Leaning on straight

    I guess that only leaves 2 options: 1- a previously unnoticed camber or line change 2- the nut connecting the seat and handlebars 😀
  21. Leaning on straight

    2 weekends ago I was at a session with Dave Moss and he talked about buying former race bikes and the new owner failing to adjust the bike to themselves, believing the bike to be best “as-is”. Dave believes this to be in error and almost implied that the bike should be gone over with a fine tooth comb. He did say all the settings should be removed and baselined for the new owner.
  22. Leaning on straight

    Has the bike been crashed? How about the installation of the wheels? Some bikes have a specific procedure regarding which bolts should be torqued in which order (you do use a torque wrench, right?). Also, where is your weight centered when coming off the final corner? Do you stand the bike up swiftly or gently bring it up in sync with the power? Just a few possibilities. That’s the best of what I have of value to help.
  23. Leaning on straight

    Does the bike go straight during other straights?
  24. Hello everyone

  25. How did YOUR weekend go?

    Oh! and the biggest thing (I almost forgot).... I might have the back pain problem solved. Focusing on screwdriver on my inside hand forced me to keep my elbows up and I think that helped a lot!
