  1. It certainly should be a slicker process but your opinion might be different if you were on the other end of such a situation.  A pal was once grateful for the thoroughness of DVLA over a bike he owned when someone who had come across an old mudguard at a jumble was trying to use possession of that old number plate as the basis for claiming ownership of the bike.

  2. I've had two (inexpensive) - neither lasted long enough to be of any practical use.

    I'm not convinced time alone means much on a trials bike.  i prefer to look back on what events I have done and assess how they may have, for instance, affected the oil.  Two hours putting round a field doing sections is not the same as two hours spent blasting over the moors.

    I'm also curious whether the back of the front mudguard might foul on the exhaust on full compression, time will tell. At least I can revert back to original clamps if it doesn't work out (expensive exercise however), a frame cut and shut cannot be so easily reversed.

    During your hot spell take the chance to remove the springs and find out if the mudguard catches on the pipe.  Better than discovering in a more dramatic fashion.

  4. You tune from rich to weak.  Set a tickover with the throttle stop screw. Turn the mixture screw in (out if it is an air screw, I'm not familiar with the Keihin).  As you weaken the mixture the tickover speeds up.  Turn very slowly until you reach the fastest it will go then turn the throttle stop screw out to reach the tickover speed you want.  You can fine tune from there.  I would start at 1/2 turn out on the air screw if you have no approximate figure.

    The general principle is outlined here http://www.amr-of-tucson.com/idle_adj.html

    There is a good Amal pdf that can be downloaded showing the various stages of the operation of a carb - can be applied to any similar carb.

     

  5. Am I correct in thinking that the TY has a crankcase drain screw? My monoshock TY did and when I put it in to semi permanent storage I filled the crankcase with oil and drained it years later - all seemed fine. You could even fill the bore too.

    A wee bit smokey on initial start up but no harm in that.

  6. Basically you can forget trials gear - it's all designed for romping in Spanish sunshine.  SSDT riders seem to get satisfactory results using "outdoor" jackets.  Those who bother with waterproof trousers seem to use what might be your farmer's leggings.

    Never having ridden it I get the impression that Scott competitors don't bother too much - they are certainly working hard enough to stay warm, but something carried in case of breakdown could save a hypothermia attack.

    In a short circuit trial it has to be really bad before I bother but over my trials gear use an old cycling jacket and stretchy PVC overtrousers kindly provided by my old employer. That's only once every few years though.

    If you get the right camo though you might conceal a few dabs☺

  7. Are you perhaps expecting two stroke smoothness from a four stroke?  They are a bit harsher off the bottom - eased by having what may feel like too high a tickover.

    In comparison with a TY 175 it will seem particularly bad as the TY has a very smooth power output, not least due to gearing and low power (compared to a typical 250 for instance).

    Got to any mountain bike area and check out how much is being spent, not sure this is as much of a problem as access and image.

    Indeed, and have you seen the entry fees for a mountain bike event?  I'd like to see what they're spent on. The insurance can't be more than for a motor sport event surely.

  9. Whilst it only takes a moment to remove the seat I'd follow the advice to tighten the throttle cable before doing anythng else.  Your massive wrist movement is spent taking up the slack so you're not getting the revs.
