The Dragon V, is a pre broken-in, 3 port engine designed to our engineers very highest specification. The Dragon V continues with the Dragon IV’s benefit of being easy to tune and within 2-4 tanks, be ready to race due to the out of the box pre broken-in advantages.
With rigorous testing of the new engine, we have been able to improve the following key items of the engine:-
Piston: The lightweight full-milled piston provides the engine power acceleration, which allows for greater torque and better fuel efficiency.
Sleeve: The hand made cylinder liner sleeve improves the scavenging and exhaust efficiency, the effect is that this further increases the engine's acceleration and provides a higher speed when compared to our previous versions, while retaining the smooth and linear throttle feel. (Note – Scavenging efficiency is the ratio of the amount of fresh air compared to gas left in the cylinder after a combustion cycle)
Head Button: An O-ring is added to the new head button to ensure the engine has a lower and more constant temperature performance.
Backplate: The new backplate improves the scavenging efficiency of the engine.
Crankshaft: The crankshaft has had its timing adjusts to further suit the efficiency of the new sleeve.
Carburetor: A new 8mm bore carburetor has been developed which is easier to tune and able to provide more power depending on the venturi inserts used. 6mm, 6.5mm & 7mm Venturis are supplied with the engine. 7.5mm and 8mm as options.
Crankcase and Cooling head: New V logos have been added to the crankcase to match the new bright red cooling head.
Recommended exhaust is the Alpha 2159, and P6 plug.
