    28.5 competition head kit

    Posted by Tom Kelly on 12th Aug 2018

    First off, the head and piston went together with ease, im not a machanic and i had no problem, I just followed the easy to understand direction that came with the kit. I broke the engine in as per the instructions, to be really honest after break in and a tank or two i was not that impressed, yes it would out perform a stock engine but i have had other engines from Rooster tail and my expectations were high and i was a bit dissapointed. I ran a few more tanks through it and then it was like a different engine, this kit on a Zenoah G 29 has a heap of power down low and up top, it has suprised me a bit, the accelerating from mid to high is impressive and the low end has plenty as well. I love the fact that with full throttle on a straight its a smooth as butter, it just sounds and performs above my expectations, you won't be disappointed. Also I'm just using a clone pipe in the dominator style.
