The dragon v, is a pre broken-in, 3 port engine designed by 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 and; 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.
