Thanks again, Cruiser. I guess the red engine does go OK with the rest of the bike. I was thinking about all black, but black and red is a nice combo. This whole project went together smoothly. I took my time over a 3 day period working on and off. Now I can customize and fine tune and modify without worrying about voiding warranties - just have fun. I wonder if anyone else with this motor kit has tried a 36 tooth sprocket...... I wonder how many other members even are running this kit.
