You know, I have had and still have profiles w/.82's and 1.00's and I have them with 2strks. I just love the throttle response, power and simplicity of the 2strks with a Macs header and my own Mousse can pipes!!!!! The two strokes can be smacked time and time again and will usually keep right on going without any probs. One of my favorites is the TT .46Pro with the above setup and an APC 12x4 spinning @ 15,000rpm[>:] This was my fav. setup for a Mojo .40. Let us know what you decide to do and how it goes.
