Don't let missing the alignment marks get you down. I've owned and been wrenching Shadows since 2002 or earlier, perhaps 2000. I've known about these marks probably 2 or 3 years myself, and then only for certain about the front one since a few days back when I took the camera out mid-message to check on it (although since the brakes were in alignment, I probably did spot it last time I had that bit off, though I could also have fluked it). Now that we're talking about it, I do remember some years back struggling to get all the bits into an alignment that gave me room on the adjustor and a comfortable pedal position, while also having the brakes work without too much travel. While memory says it was half an hour or more of extreme frustration, it was probably only 5 minutes, but it was annoying getting them right. Those alignment marks should have big flashing neon indicators or something!I've got the brakes working I never even realized there was alignment marks I had put it on way off and it's average 65° around here
At 65°F your bike should start happily without choke.
