I've taken the 79cc pred off of my bike. I ordered a happytime kit from ebay that should be here before friday. I'm not entirely giving up on the project, I just don't get enough money coming in to finish the pred project. It's very costly. The HT will be bolt on and go! I'm far more experienced with the 2 strokes anyway, and I think they look more "stylish" on a bike. The HF build is delayed. But hey, 2-strokes are still fun and it sure beats pedaling! I will post pictures, after I finish. A happytime will have no problem living in harmony on the frame.
