- 프리 브레이크 인 3포트 엔진 +8만원 상당 4점식 클러치 세트 +전용 공구 들어 있는 세트
In celebration of the release of the Dragon IV, a limited edition combo set is to be available.
Released as product code “21-Dragon IV E72”, this package will contain the following:
-A Dragon IV engine with 3no carburetor venturi (6mm, 6.5mm & 7.0mm) and P3 Glow Plug.
And a 4 shoe clutches combo set, complete with the 4 shoe clutches tool.
With the new engine, we are able to improve the following items.
The crankcase has been redesigned to improve the efficiency of intake and exhaust, the flow of fuel from the carburetor
to the combustion chamber, and this results in less losses and greater fuel efficiency, furthermore,
an increase in engine power .
Ceramic bearings: Reduced friction, lower weight, improved longevity.
The high quality material ceramic bearings are fitted as standard to the Dragon IV, and with less drag,
more energy can be applied to the wheels. It’s reduced friction, lower weight for reducing the drag,
and increasing the engine power and the speed-up function.
DEC Crankshaft: Reduced engine vibration, resist wear, good lubricity.
The new version of DEC Crankshaft, has the Alpha Patent – Dynamic Equilibrium,
which can efficiently balance the inertial force from piston pin, from conrod, and from crankshaft rotation,
to reduce the vibration of engine and to increase the engine power.
The timing on the crankshaft has been altered for more power and a more linear power delivery has been achieved
when combined with the new piston and liner.
Redesign air intake can provide the fuel efficiency, more power and a more linear power been delivered.
The piston pin improves the hardness surface and the durability in order to reduce the possibility of bending,
also made very light.
the new cooling head adds one more layer, but has been lowered for improved center of gravity
in order to handling of the car, whilst keeping good natural cooling effects when positioned in car.
