Hyper 9 & modified NovaRossi
Since everything with "Rossi" in it's name is fast, this engine (NovaRossi N21B09 PS) was a bit of a disappointment; it had a narrow powerband, high rpm, but no real grunt. The idling was unstable too. Those are actually the characteristics of a long stroke engine. Since i have experience with tuning long stroke 2 stroke engines (1 on 1 scale) i decided to give it a go. Luckily it's a simple engine. It's not quite clearly visible on these pictures, but the sleeve is ported, the crankshaft is "scooped" and the intake is timed. The Exhaust port is left untouched. The result surprised me. Throttle respons is better, it has a wider powerband with slightly less rpm, power increased big time, better fuel economy (i don't give it full throttle so much anymore), idling is more stable and the temperature dropped. Exhaust is standard HoBao, glowplug is a HPI #5, fuel containes 16% nitromethane,clutchbell is a HoBao 13 teeth, outside temperature was 24 degr. celcius.
