I replaced the kits oil breather hose with a more realistic one. I had problems with it not resting in the correct position. I thought if this were a real bike, I would just use a zip-tie. And looking at some pics I found online, apparently this is an issue on the real bike. One photo I saw looked like a bunch of rubber-bands were used to hold the line. So since I couldn't find any 1/6 scale zip-ties, I made one. I started with a scrap piece of styrene, a very sharp blade, and a micro drill. About two hours (and three failed attemps) later, I had it. No, it doesn't lock in place like a real one, but it's a tight enough fit the friction holds it tight. I have not decided if it will stay there or not. It's kind-of hard to see it in this pic (it's on the top of the frame, about in the middle of the bike), but it's also visible in one of the handle bar pics.
