This weekend I installed the new battery. I heard those stock batteries require a heaping amount of snot and force to get them out, but jeez. I was yanking and pulling and trying to find any which angle I could. Finally got her out after removing the subframe bolts. I wonder if that battery might’ve actually been slightly off from the stock size.
Also changed the fluid—driveshaft was nearly dry. Final drive was dark. Transmission was darker, and the engine oil was…water, for about half a liter. Pulled the spark plugs and peered inside with a flashlight—saw *some* spots of surface rust; didn’t look terrible, but I’m not sure what actually amounts to “terrible”. Squirted some WD40 into the holes and closed them back up.
Removed the airbox to reveal what we all might have expected, but nonetheless, it was a first for any of my previously owned 70s bikes:
Little stinkers had nearly the whole intake packed with insulation, cotton, and acorns. I imagine this is quite common on forgotten airheads. Thankfully the filter hadn’t been chewed through, so it didn’t appear that anything got down into the carbs. Good thing the seller gave me the wrong key, because I might’ve tried to start the bike up with all that junk stashed inside.
Next on the to-do list: drain that gas and drop those bowls. So far, it feels fun going back to an old, carbureted bike after 8 years of fuel injection. Any wagers how long that fun lasts?
