Glad you like it! You'll like it even more with a 3spd and turbo button, but it will wheelie a whole lot more with them-I'm fighting that problem, if you can call it a problem, right now. I have a 19t CB on order, so maybe that will help keep the front wheels down. Yes the engine will need to be retuned with the turbo button....no big deal though. Just put the LSN and HSN back to the factory settings and go from there. Enjoy that Axial...looks like you are having fun with it.
