Man what a great build. My 2c on the pipes: I like the "idea" of the Yamiya yosh pipes, but I keep coming back to the CycleX pipes.
With all the black going on, (frame motor, wheels etc) I think you might need some contrast. There is such a thing as "too much black"
Those CycleX Super sidewinders really have a good look to them. The shortness of the overall pipe still has the "race" look to them.
The only thing about that set that bugs me is the collector. Seems a bit bulky and off the frame.
The CycleX 4-2-1 race system is super sexy. I think those are going to get my vote - they have the
best of both worlds: the header pipes are black - keeping the toughness of the look intact, while the chrome/stainless megaphone keeps the vintage feel.
The collector on those seem to fit up under the frame better. The megaphone really makes that pipe - much better looking than their original version of it.
Those really are great looking pipes - those guys are really starting to churn out some great stuff.
Can't wait to see the finished bike - It's sure going to look fantastic.
I like your color choice for the bike as well.....I may be partial to orange.
