makes a great screen saver too.February 3, 2010 at 11:46 am in reply to: Whats the best wayto come to a stop at an intersection/stop sign? #24380TrialsRiderParticipantIt’s not strictly legal???
..full stop feet up sounds perfectly legit by me. Wonder what that cop would say to stopped waiting for the light to change, feet upTrialsRiderParticipantRan out of space to ride Enduro and Motocross due to urban sprawl and was familiar with Trials through the interests of an older brother and a few close friends. I started riding CVMG competition 15 years ago, enjoyed it, excelled at it and modern trials became a natural transition. …you don’t get hurt as much on modern machines and can ride much bigger stuff Once you reach a point where you can drop the clutch and leap up a 3 or 4 foot vertical rock face with only a 6 foot run, the whole time feet on the pegs, you really get hooked on the sport.
Also helps that all the competitors are really great people, always willing to help and encourage you, unlike motocross where they are generally trying to kill you with rock spray. I’m not real big on violent confrontation! …unless you threaten my dog that is.February 3, 2010 at 2:16 am in reply to: Whats the best wayto come to a stop at an intersection/stop sign? #24365TrialsRiderParticipantBoth brakes must be applied correctly to keep you in a straight line. While the front brake does provide ~80% of your effective brake force, that is NOT to say you should haul it on harder!!! doing so will get you in big trouble real fast unless you have ASBS (and you don’t) Never exceed the traction available to your front tire and in my experience engine braking is nearly as important as the rear brake itself. I rely on engine braking a lot to sluff off speed, especially from high speed. When I’m stopped at an intersection light, I go for neutral, unless someone is approaching from any direction or sitting on my ass, then I agree with jcwhite; I’m in gear, watching my mirror, everything around me and ready for anything!
…You are going to take a course I trust!TrialsRiderParticipantNot wanting to complicate things, but after reading articles like the following along with several more published by the major tire manufacturers, they have me seriously considering nitrogen fills for my street ride from now on!

…you can make your own decision if it’s worth the effort.
On the subject of tire trouble in very remote areas; my K100 came equipped with a really handy little tubeless tire emergency repair kit / CO2 cartridge tire inflater. Similar kits are available aftermarket and a highly recommended toolkit accessory.TrialsRiderParticipant30 front / 34 rear sounds about right, manufacturers generally recommend higher values at higher speeds, …would be interesting to see if it changes much with high altitude, you could test that better than most of us For comparison, I ride a much heavier BMW K100RS and the one up numbers are 33/36, two up 36/42 and two up riding above 180 kph calls for 39/42. In my experience too high pressure results in your suspension over reacting to even the smallest road ripple, and on gravel roads it feels unstable owing to the reduced foot print, very low pressure is most noticeable in the rear first when it starts to squirm, even traveling in a straight line. I encountered a rear flat at high speed once, riding two up! …couldn’t figure out why it was under-steering and felt like the bike had a hinge in the middle, until I stopped and looked down to see the rear tire totally flat. Thankfully it was the rear tire, we were both very light weight riders, both very experienced, so nothing bad happened.
Now for something completely different; on my competition trials bike I ride 5.5 psi in the front and 4 psi in the 2 ply tubeless rear, but then in trials you seldom ride faster than 30 kph and you want only enough air pressure to keep the tire on and not dent the rim when you hit the big sharp rocksJanuary 31, 2010 at 12:43 am in reply to: Building a beginner-oriented streetbike, need help… #24296TrialsRiderParticipantSeeing as you plan to use the engine as a stressed frame member, I’m curious what 450cc engine you plan to use???
