Just finished putting on the SD Stinger Engine kit 66(80cc) on my Schwinn Del Mar 26" beach cruiser! She fired right up and no problems. I'm not very mechanically inclined, but with the right tools I got the job done in a day with the help of my friend and use of tools. Now I feel like I could slap these together no problem next time around. I also want to say thanks to everyone for making great posts and threads to help with any problems I had along the way with the build. Pics will be up soon!
