Novarossi Vir-Tus .21 offroad & .12 onroad engines

Novarossi have introduced their new engine line for 2014, headed by their new Vir-Tus .21 off road and .12 onroad engines, joining last year’s .21 onroad engine release. The key development of the Vir-Tus over their previous engines is the patented shifted carburetor which sees the carburetor opening mounted to the crankcase off centre to the crankshaft which helps create a better mixture flow inside the engine which in turn improves the fuel efficiency. Other updates seen on both motors are the new main bearing that reduces the inertia of the rotating masses and increase scavenging, new cooling head mounted with 6 screws for a better seal and new balanced crankshafts with the .12 sporting a larger diameter connecting pin. The .21 offroad has 7 ports while the .12 is a 3 port engine, both coming with ceramic main bearing and steel front bearing as standard.
