Novarossi 367 Buggy .21 PLUS 2 engine!
Novarossi have 3 new engines for 2007 production which will be available by this March. But we only going to cover the off road buggy engine here. 
The 367 Buggy .21 Plus 2 engine. Its a completely different engine with new carburettor and new patented front bearing. Made for buggy drivers who demands an engine with a lot of low RPM power and long runtime.
Interesting to note, it has SG crankshaft with grinded thread!!! Now whats that??? Combustion chamber with O-ring???
Crankshaft: The crankshaft is grinded to increase the mixture flow and has a special shape to reduce turbulences inside the crankcase. The balancing is done by two inserts made of tungsten alloy and the inlet has a silicon filling to reduce the weight of the crankshaft to improve acceleration. The ball bearing was lowered to5mm. The front part was extended to improve the seal against fuel leaking.
Combustion chamber: The combustion chamber is supported by a O-Ring which is placed between the combustion chamber and the crankcase to reduce the vibrations of the combustion chamber.
Typical ‘PLUS 2′ differences are:
- Lightweight cooling head
- New carter backplate
- O-Ring supported combustion chamberThe name is actually a code: the first number is for the amount of crankcase ports, the second number for the thicknes of the front bearing and the last number stands for the amount of transfer ports in the sleeve.
Available from March, and only be sold in the ’special PLUS 2 edition’ package.
more information about the special PLUS 2 Edition package will be online soon
