It's been a while since I updated on this. I’ve been too busy to wrench for a while, and when I did have spare time I was out riding my 400f and 350 twin.
It's taken me seven months, but I've finally gotten a couple of days to finally take on the "NYC Slo-Mo Abandoned Death Watch" bike that I rescued from the trash man back in February. Turns out that under the bird#$%* and grime is a pretty nice Honda. After installing a new ignition switch and battery, then cleaning up all the electrical contacts and control switches, everything lit up -- it has working blinkers, starter, lights, etc. It also sparks on all four. I went over the whole bike with compressed air and had a ton of leaves, dead bugs, trash, nutshells (squirrels?) and other debris come off. I haven't fully scrubbed it, but it’s at a point where I can get it working.
I had an old 350f tank which I took to a radiator shop to boil out and coat the inside. For $100 it was definitely worth it to not have to go through all the steps in a liner kit, and it's a thick bright red coating on the inside. Unfortunately, it left the old paint intact and I was hoping it would come back completely bare outside -- I'll probably have it painted when I sort out the mechanicals. I took off the carbs and cleaned them out and finally got them back on (son of a b*tch). Rebuilt the petcock with a kit. Pumped lubricant into all the cables to free them up. Rebult the front brake caliper and bled the system and freed up the caliper arm.
The old oil was grimy but didn’t have water or gas in it. I went to drain it and….no drain plug on the bottom. WTF? So I pulled off the pan and found that the PO had completely (and very sloppily) welded the hole shut. Not sure why, and not sure I want to know. The pan gasket was in very nice shape so I guess he just pulled the pan every time he wanted to change the oil. Luckily, the owner of the garage where I keep my bikes had an old 400f engine in the back and sold the oil pan off it for $50 (excellent deal, considering I had it in my hands in the time it took to loosen the 11 bolts that hold it on).
I squirted some oil in the pistons and the valve adjusters, but had to call it quits for the day. Tomorrow I’ll pick up a gallon of gas and head over and try and start it. I promise to take some pictures and video if it does run, or even if it doesn’t.
