KBO2,
Your project is awesome. Everytime I reread it, it makes me want to run up to my garage and lock away the outside world! Look at all you learned over these years, and be nothing but proud - even your "mistakes" were a huge learning experiance. As for the seat, get the RCC seat up and running, and use the bike come Spring. When you are ready for another new project, try your hand again at the seat you want. Regardless of a bought seat, you still MADE this bike from SCRATCH!!!!!!
I can't wait to see vids of you ripping this Beast through the mountain passes this Summer!
