The engine also appears to lack bottom end grunt compared to say my OS Speed Spec II. I am using the Ninja pipe that came in the engine kit.
Anyone out there had one of these and how did you find the tuning and overall performance of the engine.
I am contemplating having the engine worked up to improve it's performance.. is this worth it?
