How can I get involved in motorcycle and kart racing in Thailand after moving from the UK?

A user has recently moved to Nonthaburi, Thailand, seeking advice on how to engage in motorcycle and kart racing after a successful 40-year karting career in the UK. They expressed interest in contributing to a race team with knowledge in tuning and building two-stroke engines, without seeking paid work. Additionally, they are looking for clay pigeon shooting activities at reasonable prices. Several comments suggest looking for racing groups on social media, visiting local circuits like Bira, and even starting a personal project involving engine development due to potential challenges in sourcing parts for existing two-stroke engines.
