Spot on. A few people have said it in different ways in this topic, but it doesn't matter where the engine comes from or how cheap it is to buy, riders will understandably tweak it to try & get an advantage, then the costs will spiral. The only way to cap costs is to have a standard engine with a ban on any mods (for league racing - you'd have to have more freedom for GP riders).
Ideally, each track would have a stock of engines and they'd be allocated at random at the start of a meeting. Ideally.................was that a pig that just fluttered by?
Happy new year
