The 14-year-old finished the preliminary rounds with 13 out of a possible 15 points, after taking four wins and a third placing behind Matthew Gilmore (NSW) and defending titleholder Brody Eves (Qld), before going on to comfortably win the final.
Gilmore also did well, winning three of his heats before clipping the rear wheel of local rider and current WA champion Matt Marson and being excluded from the re-run of the race.
The event also included senior solo races with Italian resident rider Paco Castagna winning all five ahead of WA titleholder Daniel Winchester.
The next day, Pinjar Park hosted the Australian under-16 125cc pairs championship where Jaimon Lidsey again took the title, teaming up with Declyn Adams to win by just one point ahead of Matthew Gilmore and Keynan Rew. The WA duo of Declan Knowles and Matt Marson came fifth.
Pinjar Park will host the 2014 King of Pinjar and Gordon Rowland Memorial event this Saturday night.
