Ielasi Tuned have introduced the IDT.21-4CQ 4-port “square” engine. The company’s most powerful off-road engine so far is designed to offer great power at both low and high RPM while the 4-port setup makes for a linear power output and low fuel consumption. The engine comes with a R7 conrod which is machined from light aluminium and ultrasonic-checked for improved reliability. Other features include a selected and matched piston/liner assembly for best possible compression and durability while the carburettor used is a reverse-type Novarossi offering to provide high idle stability, precise tuning and higher mid to top range power. The package is rounded out by a new cooling head with etched Ielasi Tuned logo.
