I recently ran in a new MR Ninja .12 that I purchased some 18 months ago. I am having heaps of trouble tuning this engine. I haven't been able to find the basic factory settings - nothing on the CD. The idle seems to stay high and then drop down, I have played around with both LSN & HSN and can't seem to get a good tune that holds.
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?
