  1. About March 07, I had a set of forks built by Ed of Trackside Engineering in Wisconsin. Ed has since sold the business and the new owners haven’t returned any of my calls, emails or requests for information, so I now turn to you guys for advice. The forks were built with Racetech 1.0 springs and Racetech Gold Valves part #FMGV S2040nv CTRL# 040297 (from an old email between Ed and myself). I recall talking with Ed about some other kind of pistons, valving, etc. and honestly at the time I was on information overload (in spite of his excellent communication skills). So I’m reasonably sure the RT stuff is on compression side and he used a set of pistons he salvaged from another rider’s setup to use on my rebound side. I have no idea about the brand, weight or oil level used. He also installed new bushings and seals. During our pre-return shipping conversation, I recall him saying something about stiction but I have no recollection of what he was referring. At the time, I was still struggling with suspension vocabulary (and still do apparently) and so I didn’t retain that portion of the conversation. Possibly he was warning me to be aware of it in the future, that he solved the problem or that the problem still exists. At a local hangout I ran into Terrence, an all-around great guy, the proprietor of A&J Cycles, a former WERA racer and AMA Tech Inspector. I spoke with him about some of my handling concerns and trying to articulate the inconsistency I was experiencing. After I invited him over to my bike, he lifted on the front end and when it didn’t return to it’s original geometry he said that I should go inside the forks and find out why it has excess stiction (is this the correct term for this?). Terrence also complained that the 1.0 RT springs may be too stiff for a 233lb dressed weight on my 02 F4i. I haven’t conceded that point yet, as I’ve ridden on this setup with an Ohlins rear (properly sprung by Kyle and verified by Ohlins) since the abovementioned time. I told him that I wasn’t sure of what it feels like, but I believe I may have bottomed the forks a few times on the brakes at Summit Main, so I reasoned that I may have too little spring!?!? Further in the conversation I communicated that at times the bike seems on rails, goes where I point it, at other times it doesn’t want hold the line on exit and other times it falls mid-corner (Michelin Pilot Power tires). I have always blamed either myself for the inconsistency or blamed a recent change in rear preload from fiddling with the adjuster for 2-up rides. Now here comes the ending: Since I just had the shock serviced due to a malfunction, AND since I had this suggestion from Terrence about stiction, AND due to the fact that I’m doing some work to the bike anyhow, I want to service the forks; I want to eliminate them as a variable in my riding results, however I don’t know WHAT to do because of too many unknowns and uncertainties. I haven’t allocated money in this project budget to send the forks out, and besides, whom do I trust to do the work (???), and Terrence is too busy. So I reasoned that changing fork oil can’t be that hard, right? And while I’m doing that, I should be able to visually see if there’s something binding and causing the stiction (which I understand that some of it is normal friction from the bushings and seals). A confused mind can’t make a decision. Can someone help me get un-FusterClucked?
  2. So how is the bottom point calculated? I have asked this and have only gotten a range. I am close to being convinced that it's time to disassemble my forks (a whole other story). If I have to do it in order to find the bottom then it's +1.
  3. Yes, I'm all about the XX crew chief.
  4. I've ridden balls of foot street or track for quite awhile now and don't feel in total command otherwise. I just wondered why the Pro's don't. BTW- Stock rearsets on F4i (for now).
  5. I saw somewhere that Keith says to make up time in the fast sections and just get through the slow ones. Unfortunately, at my level my club doesn't allow lap timers. I have to get bumped for that (soon I hope). You say you're not familiar...and I didn't make it any easier describing it in reverse either (my bad). You've answered more questions than I've had the vocabulary to ask. I've been a lurker on this board for awhile, mostly reading Keith's articles. I've only recently decided to register and post. Keep up the good work-EVERYONE.
  6. The section is a downhill series of esses ending with a flat hairpin right. By being easier I meant it felt like it flowed better than the line I had been using. It's at Summit Point, Shanendoah Circuit in West Virginia. The part that I had to change was not going in so deep into the uphill right. At the crest, is a left, which then starts the ess section. It felt like it was less energy, I didn't have to get as hard on the brakes at the top of the crest.
  7. I know it's old but I had to respond to the comments about Rossi hitting Gibernau. If you go back to that last lap where Gibernau ends up off-course, you'll see that Rossi got underneath him because Sete ran wide and ran into Rossi. Rossi then came wide at the exit of the last turn on the last lap and kept pushing until Sete was in the dirt. Rossi said it was a mistake that he didn't mean to run that wide on exit, but personally I don't believe him. But IMHO, Sete did it to himself cause Rossi got in his head. I can't wait to see what'll happen when he saddles back up (this is gonna be good, now that he has an ally in Casey).
  8. So here's my question from this topic. I had a similar experience at a trackday a few months back. The cones were laid out for TP, Apex, exit and there were perhaps 2 TP cones that I thought should be deeper. Why not, I could hold throttle longer, turn and still make the corner, right? Later in the day, I decided to "try" the established line and I found that it wasn't the upcoming corner that worked better (I thought it was worse and so goofy) but it made the upcoming SECTION easier. So based on Tweek's original question and my experience, it is just an "experience is best teacher" thing with knowing where you want to put your line?
  9. No, just put that on your To Do list too. :-)
  10. I agree with you 100000 percent on the sense of speed thing Cobie. However, I had been suffering with confidence problems. And doing it this way, I could enter at a predicable speed each and every time until I was satisfied with my line and throttle control (smooth roll on, looking through corner, etc). Then I could focus on small increments of speed increases 2,3 or 5 mph and remind myself to keep the SRs in check that I was well within the limits. When the confidence picked back up and faster riders joined me...the speedo had to go and the speed climbed using sense of speed. But alas, Soft Science is on my "To Do" list.
  11. In my local area there is a section that has become somewhat of a practice area. I had realized how my poor throttle control habits were affecting SOOOO many areas of my riding and decided to change that. I used this area of sweeping turns. It takes about 2-3 mins to do the whole circuit. Over a 2-3 week period I worked this area, disciplining myself to stay in 3rd gear, not use any brakes and to stay in the gas and DRIVE the corners. I started at a well controlled speed and worked until I knew I could take each corner at a certain numbered speed as indicated on my speedo and I setup FOR THAT SPEED each time. Buddies that have ridden this with me, did not have the patience for this but I kept to my discipline. It has helped tremendously for me. Perhaps you should find a section that you could use where repetition is your ally. Keep it short and make measured progress.
  12. For the longest time, I've heard that the "proper" position is to use the balls of your foot on the foot pegs. I noticed that top level including MotoGP guys lock their heel step onto the pegs. Are they just at a level of performance where they can transcend the rules or is this no longer a "rule"?
  13. Glad I fired up this discussion: Racer- I agree with you that people should take responsibility for their own education. Nuff said about that Regarding T2, I read a thread posted by Mr. Code where he says that when he wrote T2 he didn't have the best understanding about the concept of pivot steering and promised to update it in Twist 3. That was in 2003. OFF TOPIC: Cobie, et al My only Code posessions are the Twist 1 DVD. What would be the best investment in study material for me? (I own other publications too, so I do read) Should I wait until the T2 DVD comes out and purchase it and risk redundancy by purchasing it AND the T2 book? Or do they not cove the same information? ---- I suppose for that matter I could ask the same question about T1 Book vs DVD--- (hey I did, but never got an answer) PS- Cobie, you're in the T1 DVD credits, but I can't spot you. Where are you?
  14. I'll give it a shot, sir. Thanks for the swift response.
  15. I have never had a bike with much. I would look at everything to make sure it is straight(axle, tree, triple clamp). One thing I do is with one tube tight and one loose I use the front axle to set the height (when it spins free in both legs). All forks are not the same and a little tention on this dimention could bind the fork up. Will I also have a issue with stiction and a local guy suggested that the forks will need to be torn apart. No mention of front end misalignment (which I have a slight misalignment). I had my forks revalvled and sprung about a year ago. He suggested that it may be time for oil and or could be another issue. Since I'm now doing this on my own, should I invest the time tearing them down or other more important things? The stiction wasn't even noticable until he pointed it out.
  16. This is a very interesting topic and I'm glad I found it. I too am having a similar issue. I have about 4 trackdays under my belt and I'm finding it tough to kick those street riding habits (trailbraking). My best trackday was when I instructor convinced me to stop trailing and to quick flick the bike. The street has brought that habit back. Now that I have a new street riding partner (a more advanced rider who's also a track rider) we're working on my cornering confidence which showed how and why trailing has been a limitation for me. I guess what I'd like to know is: is there something that can be done to accelerate my habit breaking and help reinforce it and to show me WHEN it's appropriate to use the trailing technique (like Squirrels)?
  17. A couple of years ago, I purchased the DVD of A Twist of the Wrist. I had long heard of the books Vol 1 & 2 and thought this to be a great way for me to visualize the lessons. In reading some of the forums, members make references to either Vol1 or 2 or sometimes the "Soft Science" book. Should I still purchase the Twist of the Wrist books or do I have all of the content in my DVD?
