It has been a while since I visited this thread (or rode my XL), and I am very impressed with how it all turned out! I really like the orange around the number panels; I think it really ties everything together. I look forward to seeing what you come up with for the seat cover.
Now I'm motivated to get my XL out to do some riding, even though it doesn't look anywhere near as good as yours.
