  1. Can anyone tell me what the racing configuration is for the Streets course? Specifically, does it include the tight esses that CSS students ride during the schools? Bill
  2. Will, I haven't been checking my differential pressures. I'll look at that and see how I go. Thanks for the input. I knew there should be an ideal pressure differential, but I didn't know what it should be. Does this value vary much from tire to tire? I put a set of Rennsports (RS2 front RS3 rear) on last Sunday with the same pressure (31 rear / 33 front). Next week I'll measure these cold and then heat them up in the corners and see what I get. I'll be at big willow on Monday the 24th and I'll check the differential again there as well. Thanks again, Bill
  3. Will, I ran the new front last weekend on mt. palomar with 2 psi higher pressure than I was using before. I decided to put off messing around with the ride height. My cold pressure for the rides were: 31 psi rear, 33 psi front. I had been running 31/31. I rode both saturday and sunday with this setup and the front tire looks much more like the rear without the extra strands of rubber hanging off. Thanks again. Bill
  4. Will, Thanks for the input. It is greatly appreciated. Front weight bias makes sense. The ride height increase I made in the back may have contributed to this. I put a fresh front on last night. I'll take it up to the mountain this weekend, ride it Saturday and photograph it. Sunday I'll clean off the hanging bits, drop the rear two mm, ride again, photograph and compare. Maybe I'll see something from this. Would it be worth my time to make a static front / rear weight bias measurement? My employer has a set of scales designed for setting up race cars that will allow me to put a separate scale under each wheel and get individual weight readouts while I sit on the bike. WHC
  5. At a recent CSS held at the Streets of Willow Springs track, I noticed that the school made some potassium and salt tablets available to the riders. I assume this is to combat dehydration and electrolyte loss. I used these and seemed to be fresher and more alert on the 170 mile drive home after the class than I expected to be after a day at the track. My question is: a) What is the potassium tablet called (I recall that the salt tablets were sea salt) and where can I get this? I remember that it wasn't just potassium, but I can't recall what it actually was. What is the recommended dosage? Please advise. Thanks, WHC
  6. Issue: Front tire appears more "shagged" than rear after canyon or track riding. Bike: 2003 R1 Tire: Metzeler M1 Setup: 35 mm front, 25 mm rear sag Springs / valving: Circuit 1 front, Penske rear (front sag was 43 mm with preload adjuster maxed out with my 210 lb. weight) Whe I was running the bike on the stock 208 ZRs and stock suspension, the rear tire would always look more abused after a quick run through the canyons or a track day. After the suspension and tire change, the front tire has consitently looked more shagged after spirited riding. The bike feels good but I can't help but wonder if I have something out of balance. Perhaps tire pressure or ride height. I did raise the rear ride height about 8mm after the suspension change because the front felt slower after reducing the sag in the front from 43 mm to 35 mm. Any comments based on experience, etc. would be appreciated. WHC
  7. I recently passed through this barrier and found that taking my mind off of dragging knee and just riding did the trick. Make sure you are confident in your tires and your overall bike setup. Gradually increase your corner speed. I also found that it was helpful to get comfortable with a specific amound of hang off and knee-out angle to use on all corners where significant lean was involved. This results in a very stable bike going around the corner because you're not moving your body relative to the bike while you're turning. Then it will just happen once your confidence and corner speed are sufficient to require enough lean angle. You will feel a light tug on your leathers and hear that puck scraping along the ground. I found that once I had my knee down on the track, it was very natural to do it on subsequent laps and sessions. You may be only 1/2" away now and not realize it. I don't recommend doing this on the street. I know many people do, but I feel that it cuts too far into your safety margin. Good Luck!
