I desire all the K0-unique parts.
I am willing to settle for repro parts as long as they are IDENTICAL to the originals. airboxes and sidecovers are already made, and there is even the place in Japan that sells smooth oil filter covers, wrinkle tanks, ducktail seats (on a metal pan I hope) and other K0 stuff. Problem is, most repros aren't identical to the originals.
However, I am REALLY serious about wanting the recessed ignition and black kill switch. I've seen LOTS of SWEET K0s that were restored and they have red kill switches and the wrong ignition. The ignition alone is more than 700 bucks if you can find them because no one wants to repro them. Same with the right-side controls.
I would prefer, and pay a premium for, a totally original bike, but I would take one that had some wrong parts as long as they were parts that could easily be replaced with correct ones. Problem is, when they ARE missing parts, it's the hard-to-get ones like the ignition and kill-switch.
