So, since I've got some work to do, and some time to do it, I figure I'd create this as a place to show what I'm doing, and to keep a log to myself of what I do to it.
Current plans:
-Is missing a mirror. And the stock ones are kind of ugly. So I have Chrome rectangular mirrors that should be in soon.
-Front brake is spongy; master reservoir has a screw that's snapped inside it (to hold the cover on). Bidding on a master cylinder right now, so I can steal the reservoir and cap off it. Will go on asap. If that's not it, then it's likely that it's the front brake pads. At which point I'll replace those before next week then.
-Need a cover yet. Integra fills garage, so I'll work on the bike in my driveway. Don't want this to get messed up by being rained on. Or isn't it a big deal?
-Have a Windjammer SS fairing, but the wrong bracket - 1972 CB750 bracket. Need to sell this to buy one for mine. Or find someone looking for a trade... It does have something on the bracket, I'll get the number off it tonight. Also need to make a wiring harness for it, and put a new cigarette adapter into it.
-Plan to do the valve adjustment asap. My dad's back from Florida on the 29th and I want this baby wrapped up by then.
-Going to pick up some chain lube tonight, and check the slack/adjust it, clean it, and lube it tomorrow. I remember seeing that this is best done when warm, after a ride, so I'm going to adjust it before riding, ride, then do the lube before calling it a night. Won't be warm, but it'll have ran a bit at least.
-Need to adjust something - Dealer said the chain is hitting the center stand. Is one or the other adjustable so it doesn't hit? I need to look at it yet to see what's going on precisely. I haven't heard it at all though.
I'm going to clean the carbs sometime, but not sure when. For now, I need to get on the thing and ride it! I'd say I'm excited to own a bike finally, but that's an understatement. Slight understatement. When I do clean 'em, I will probably use this kit:

He's on vacation, so he took down his usual for-sale page. But that shows what I'm looking at. Since it was mentioned that my air pump may be bad, this guy includes the stuff to fix it. And a complete tear down/rebuild guide.
I also need to track down a headlight/turn signal switch. Mine's cracked straight through, and looks like crap. It does work, but would rather just swap it out if possible. Anyone have any leads? I've searched some, but haven't found anything.
I'll get video up tonight of the bike.

Turbos, Hondas, 4-bangers, what could go wrong?
