I would say the biggest problem with the 1st version CRF's which I have are that they are tough to tune and don't hold a tune very well. They also don't have very good throttle control from bottom to top. It's almost like an on off switch. I currently am runnning a Sirio Evo IV Sti and Picco IDM. Both those motors are very fast, are easy to tune, have very good throttle control across the entire rev range and hold their tune very well. I was just wondering if this new version of the CRF is that much better than the 1st versions and how it stacks up to what I am running now?
