  1. Hi From Nz

    in Introduce Yourself

    Posted

    Gday Iain,

    Welcome to the TC community.

    Where abouts in the Sth are you. I see Nelson has quite a strong trials following.

    I was born in Seddon, living at bottom of Aus mainland at the mo'. Look forward to riding trials in NZ down the track.

    Cheers

  2. What Were Your Most Common Mistakes When You First Started Trialing?

    in Trials Training And Technique

    Posted

    Don't underestimate the bike. I fived a section 3 times this last weekend before I stopped thinking I needed to powerblast my way up a long climb (thinking I needed lots of momentum). I watched some little kid ride up the steepest part sitting down. So I stopped trying to race with momentum and just rode up nice and easy feathering the clutch for grip and life was much easier.

    less speed with a feathered clutch = LOTS more grip than moving fast and applying lots of power. I kept sliding out ont he cross hill. Oh well I won't forget next time.

    Too right. I find small pulses of throttle helps too, not enough to throw your balance, but just helps let the wheel speed match the ground speed and bite the terrain.

  7. Balance Training

    I am sure this has been mentioned on this site before and i am no expert having just got back into trials after a number of years road racing but i will let you know how i practice.

    1 Use the tyre pressures that you would use in competition.

    2 Place you bars half way between straight ahead and full lock (i point mine to the left)

    3 Place your feet on the pegs and if the bike starts to fall to the left turn left slightly on the bars and if it starts to fall to the right move the bars a little to the right.

    I have a trials pushbike but find this of little use regarding balance (just my opinion)

    I find that if the engine is running that it is easier to ballance the bike,could it be the gyroscopic effect of the crank? or purely physcological?

    let me know what you think.

    And of course if you have your engine running make sure you are in a well ventilated area ie

    outside :closedeyes:

    IMO this is good advice.

    Just remember to also keep the brakes locked when balancing.

    Work the front under brakes, to get some purchase at rest.

    Keep your feet out on the pegs, end of the peg should be in the middle of your foot.

    Knees bowed wide, to allow the bike to move independently of your body and lower your centre of gravity.

    I use the same technique on my trials pushy, with a bit more pedal rocking. Not the same feel but similar.

    I think it all helps, even the Wii. Riding more is the best though.

  11. Track Stand

    I thought a track stand was slightly rolling forwards and backwards on an incline? You will soon get a big fat 5 doing that in a trial :D

    If you want to balance on the spot, turn your bars halfway between straight ahead and full lock to start with. Stand on the pegs and instead of using your weight, nudge the bars to the right if you're falling right and to the left if you're falling left.

    For practice, on hard ground let your tyres down but don't have them flat. It's easier on soft ground, stick the front wheel in a rut and you will be able to balance all day long...

    Yep do what Kinell said. Pushy uses more body the Moto uses more subtle bar movements. Let the bike fall slightly to the side you are turning to get the front edge biting into the ground more. Keeping your feet on the pegs/controls is best, extra movement (swinging the leg) just has to be reeled back in to move. I'm sure you'll get it sussed soon with your pushy balance skills.

    Yep good fun going to get the milk from the shops, another great aussie invention.

    The speed wobbles can spit you down the road in a second though.

    Here's another fun ride,

    This is called the Dirtsurfer, it's unpowered but more stable.

    Powering it up.

  16. Practice Courses?

    You only have to level under the tires. Slope it slightly back into the slope. Select tires of a similar size.

    Put a few stakes down through the wall for extra support and you can also tie-wire the tires together. Pack each level tight into the edges of the tires to keep it even.

    The dirt fill brings it up to level. This terrace took 11m of packing sand. Heaps cheaper than any other terrace wall. The coach bolts in a conventional wall were going to cost the same as all the fill and a retaining wall still needs infill.

    I got the idea from Earthship buiders in America. Plus it re-uses a wasted resource.

  22. Have A Guess What A Rev 3 250 Rebuild Will Cost?

    in Beta

    Posted · Edited by Betabro

    Hi All,

    Well the Beta rattle got unbearable, so I dropped it in for diagnosis before a catastrophic failure.

    Result, Bottom end bearing nearly siezed, Crank bearing was rough rolling. Piston had a small blow past the ring.

    Turns out it already has a 270 bore.

    So it's getting a rebuild. Any guesses on what it will cost?

    Cheers
