Torini Gearing for South Australia
This is recommended starting gearing for Clubmaxx medium, or Supermaxx Heavy.
Lighter drivers may prefer to remove one tooth and heavier drivers may choose to add one tooth.
Gearing in 4ss can be a personal preference and is a balance between corner exit speed and straight line speed.
Compromising straight line speed by adding more teeth is often effective in this class for overall lap time.
Looking after your Torini Engine
Always Oil your air filter using quality air filter oil such as Maxima Fab1 or Motul.
We recommend spraying the inner (main) and outer (foam) filters with oil. Be careful not to overoil as this can block airflow to the engine. When the filter needs cleaning you can wash out with degreaser and allow to dry thoughly before re-oiling.
Failure to oil your filter WILL shorten your engine life.
Run Genuine Torini Racing Oil, To ensure the best life for your engine and warranty coverage we sell and recommend genuine Torini Racing oil. Change oil regularly, every 2 hours for Supermaxx every 5 hours for Clubmaxx.
Keep Head temp to a maximum of 200 degrees,
Whilst the engine will be fine for brief periods of hotter running, a 200 degree maximum will make the most of your engine life. If you do not have a head temperature gauge, running a 95 Jet will always be safe (with the 21' spec emulsion tube)
Make sure Chain is aligned carefully, and ideally with a laser system. If running DSK system, align sprocket carrier without the guides fitted at first to ensure a perfect alignment. Chain tension should be free enough that the rear axle spins freely and there is no resistance from chain. This will be looser than on many 2 stroke karts.
Gear the engine to hit the limiter at the end of the longest straight on the track for a brief time, Running the engine on the limiter for a prolonged time can lead to premature engine wear/ failure.
Tyre Pressure for Vega VAH?
12.5PSI Cold (or between 7 and 20 PSI)
Start with 12.5 PSI cold and work from there
I personally use 10.5 PSI cold almost every session!
Depending on track conditions, driver preference and chassis setup this tyre can be competitive from 7 PSI through to 20 PSI. Low pressures work the sidewall of the tyre more and provide more bite, while higher pressures heat the tread surface quicker and provide faster straight line speeds. What works for someone else may not work for you so test and find what does!
Fitting a Torini Engine
T4 Specialise in fitting 4 Stroke engines, but if you are giving it a go, you will need to know that the standard Torini engine plate does not provide enough offset for most karts on the market. Karting Australia have provided an approved method of drilling additional holes to make it work well. please see the following link
Alternatively T4 Can provide a fully adjustable Odenthal engine mount that makes fitting a breeze.
