Results: Nomads Trial June 2018 - Welgelegen Farm

The trial was a huge success.  The weather was cool but the predicted rain held off until after the sections were cleared and the results announced.

This trial had 9 sections, the extra section being a hill-climb.  Since access to the hill-climb was via a narrow single-track, and Sean the organiser wanted us all to do it together for safety's sake, we all went there on the first lap and each did it the required 4 times.

How do you avoid spark plug failure during a trial?

  1. Never leave your bike's fuel tap on when you are not riding.  This is especially important for the journey to a trial - the vibrations cause fuel to leak into the cylinder and wet the plug, and it becomes difficult or even impossible to start the bike.
  2. Use a new spark plug at the trial.  Nothing beats the ease of starting, the reluctance to stall, and the pure performance of a new spark plug.  Since plugs are about R35 each, it is worth it to have a new one every monthly trial.  One strategy is to fit a new plug for the trial, then swap it out

What oil/fuel mix should I use?

In a two-stroke trials bike, we generally use 15ml of two-stroke oil to 1l of petrol (i.e. in a 5 liter fuel can, add 75ml of oil, and in a 10l can add 150ml.

Follow the instructions in the bike's User Manual.

Also, be aware that not all two-stroke oils can operate at such low concentrations.  For example, Castrol Power1 Racing synthetic oil is not rated at such low concentrations.  I use Ravenol synthetic.  Be especially wary of cheap oils, but check whether an expensive oil is rated at 1:66 mix ratios.

What tyre pressures should a trials bike have?

Front: 0.5bar (50kPa)

Rear: 0.3bar (33kPa)

Naturally, this is average.  If you are riding on sand, mud or low traction surfaces, you can go lower than that.  If you are quite heavy, riding rocks and hard edges, or generally hard (aka a bit clumsy) on a trials bike, increase the pressure slightly to protect the rims.

Yet another brilliant trial.  Thanks to Brian Barson for clearing and setting the sections.  The weather was clear, and became a bit warm toward midday.

Results: KPR Fun Trial at Zonnebloem - Feb 2018

On the 18th of February 2018, we held the KPR Fun Trial at Zonnebloem.

The weather was cool, with a soft breeze, and started overcast but cleared up later.  The piste was dry - perfect trials weather.

The sections had been set all around the lower field, which made for short, quick laps.  There were only 11 riders, and although we took our time on the walk-throughs, we completed the first lap by 12, and the remaining 3 laps by 1pm.
