I diassembled the carbs and petcock on the CB160 last night, and found the anticipated dried fuel residue. As is typical, one carb was full of the stuff, and the other was much cleaner. I soaked everything in carburetor cleaner, and it all cleaned up nicely. I reassembled everything with the original gaskets, which appear to be serviceable for now. I will replace them all in the long term, but I want to get the bike running first, and see how the existing jets work at this altitude. I live at 7200 feet and most of my riding is much higher, so I often have to use smaller fuel jets and larger air jets to deal with the altitude. I'll order new gaskets and o-rings when I order the new jets. (I might do things differently if the carbs were difficult to get on and off, like on the four cylinder Hondas. The Cb160 carbs come off in a jiffy, though. This whole engine is so simple and accessible, working on it should be a breeze. I ordered new tires (trials type, since I plan to use this bike mostly on forest roads and in the Red Desert.) Also picked up new tubes yesterday, and a new chain. The old sprockets look like they were hardly used at all, (with only 4000 miles, I guess they WERE barely used) but the chain was horribly rusty. I'm surprised I didn't break the chain while rocking the bike back and forth around the garage. I'll pull the back wheel when I replace the chain, and check out the brake and bearing conditions. If the back is like the front, I will be thrilled. It amuses me that so many motortcycles wind up being used for such short distances, then parked for decades. I've done several car restorations, and the mechanical parts on old cars are nearly always worn out. On so many old bikes, the internal mechanical parts are basically unworn. This looks like another bike that will be back on the road with litle more than a new chain and new cables, and a bit of cleaning. Why do people abandon motorcycles with so few miles on them?
