  1. Your observation is correct. Lowering the front end increases the instability of the bike. Part of stability is the bike acting neutral while leaned over, a phenomenon that you described. Neutral means that it leans only when the rider countersteers and that it requires little or no effort from the rider to remain leaned over. As the geometry is created by the full suspension it behooves us to consider the shock. A good suspension tuner will create an ideal height for the shock. Depending on the model of the bike they can many times add a few millimeters to the stock height. That raises t
  2. Everyone is allowed to post so do not worry! Cobie may be checking on your specific knowledge and what skills you may have been exposed to, for example if you had attended the school.
  3. Hey John,

    Not sure I responded to your report, but thanks for doing that...the moderator got it down pretty quickly.



  4. "Racing" could refer to racing techniques, but I think it means discussions of races and riders. If so, I would use this opportunity to rename it to something more meaningful like "Racing League", or "Professional & Amateur Racing Leagues", or such. I do not feel strongly about the whole naming list. The Techniques forum is the big one for me to revisit and search. I will be ecstatic with any improvement in research capability.
  5. I do not see the "sort" option until after I do a search. It would be nice to set the sort up front rather than as a second step (I could be missing something here.) If there are choices for the default sorting of search results then I would prefer oldest posts to newest posts. Many searches today prioritize the relevance of the results. However, if you can accurately group posts by topic and return a high percentage of relevant results, the "relevant" part may already be taken care of. Also, the built in forum search engines tend to be terrible. When I search this site today I many
  6. Perhaps separate expendable bike hardware such as tires, brakes, and fluids.
  7. "Welcome to Pages" still shows up for me. Thanks for the effort. If this forum software has the capability of article categories or meta tags, those tools might help group existing articles with minimal effort.
  8. Can you delete or hide the "Welcome to Pages" article? I have no security access to enter it and so it will show in perpetuity to us users as an unread article. As new content appears I navigate via the "unread content" link. So for brand new content, the organization is moot for me. To your point about using the site as a reference, I revisit content just like periodically reading TOTW. I would love to have the entire history of technique articles organized into categories such as throttle, braking steering, road conditions, etc. so that there would be an inherent helpf
  9. You must believe me when I say that I was extremely cautious before asking about this, painfully aware of how the topic of steering has generated an infinite volume of counterproductive babble. Jaybird, I do have potential riding conditions. I might even test this today. I have tried the push-pull method. In my initial attempts I inadvertently generated excessive grip/tension in the pulling hand. I find that feeling the pressure of pulling on the throttle was particularly disconcerting and made me question if I was altering the throttle (I do not think I was, I think it was a ment
  10. Dylan, I have only found fleeting statements in TOTW where Keith writes that one can use pulling of the bar when steering. Can you expound a little on the topic? Is there a need to become skilled at push-pull steering, particularly if pivot steering is working well?
  11. Is there a vacuum synchronization on this bike and has it been performed regularly? An imbalance in vacuum between the two cylinders will exaggerate the V-engine's poor off-idle response.
  12. I did not think much about the fact that you were perfectly attached still, but should have. Here is a scenario: You are turning left but now countersteering up and come across the spring. It nails the outside of the front tire, perhaps lodging underneath, forcing the wheel to go hard left. That would countersteer you into the ground on the right. You would have perceived the sensation of a severe steering jerk methinks. Does this sound plausible? Is there any evidence of impact damage on that front tire or wheel?
  13. I am no expert, just a rider. Since no one has responded as of this writing, I will happily chime in. If the rear slides out and continues sliding unabated, this will result in a relatively slow lowside, the same that you expected. If the rear begins to slide even for a moment, then regains traction, that can generate a rotational torque that flips the bike outward in a couple of milliseconds, resulting in a highside. That event is so fast and powerful that once it is initiated there is no recovery. You pointed out several traction hazards from that day. If too much throttle exceeds
  14. The question is difficult because the problems are not obvious to me, some of the riders appear steady on the controls, and also some of these appear to be going uphill (although that could be the camera perspective) which would add helpful load to the rear wheel. This has me thinking about the bicycle coasting question. Are several of these riders coasting from too little throttle? You asked for force nomenclature, the rear would be unloaded, generating less friction than the centripetal force of the turn. The front wheel would have excess weight and thus adequate traction.
