When I have problems like that I am so mad at myself it takes awhile to move on. My condolences. We are all our own worst critics, especially in these kinds of projects.
Experience always costs.
The bike is beautiful, I love all three original colors, candy blue green is my favorite and I rank gold and red both after that. Great bike.
In some ways I think the K1's are maybe the best just because of the carb rack.
