Speed/Ninja crank
I have a Speed and what they said about the speed crank with tung weights is correct, it also has the black coating, not sure how to tell about the timing. Our speed motor is great, it is blaistic, off on power, thats why we tried the ninja, it has smooth power, but inconsistent tuning. I ended up puting our backup V-Spec in just before the main,its been in the box for 3 months, I just leaned it out 1 hr on top after the warm up, and after the main it came off at 230, OS solid consistent motor, but I'mstill gonna try just swapping the cranks and I'll let you guys know how it does
