I HAVE A X.12 I WANT TO PUT IN A NTC3 BUT THE CRANK IS BIGGER THAN ALL MY OTHER MOTORS. CAN ANYONE TELL ME WHAT TO DO TO PUT A TWO SPEED CLUTCH AND FLYWHEEL ON THIS ENGINE. THE SHAFT IS AS BIG AS A .21, AND IT HAS A PILOT SHAFT FOR THE CLUTCH TO RIDE ON. WILL THIS WORK IN A NTC3. ANY ADVICE WOULD BE HELPFUL.
I have an RB x12 in my tc3 foing on 4 years now. IT fits right in. Everyone knows me at Floyd as Charlie with the tc3. I replaced the p/s/ conrod rwice. The end of last year, I pinched the sleeve possible a little too tight. Took a long time to break in again. Last 3 times out it flies. Just does not have the topend of some of the newer engines novas (or my ps12). But with the massive bottom and mid range, it is still quite competative especially in the tc3 with no drag on the drivetrain.
