I've added another Invader to my shop, after deciding that the 1980 440 I bought early this year is too rusted out to resurrect. This one is a 1978 440. It was literally on my way home from work. That makes two Invaders I've bought within 15 minutes of home.
It's in decent condition and complete, definitely vintage rider material, and maybe even show ready after it gets polished up. It runs, but the previous owner informed me that there were no brakes. Looking in, it looked like the brake pads were gone. I figured they were worn down.
Today I went to putting new brake pads in. After unbolting the radiator and removing the oil tank to gain access, I found that the disk was actually bent, and someone had completely removed the brake pads. I can't figure out how this would have happened, but it did. So off came the chaincase cover, and secondary so I could remove the jackshaft and replace the disc with one from the parted out Invader. The jackshaft bearing needed to be replaced too anyway.
That's as far as I got today. I did not get any photos of the sled yet, that will have to wait until it's back outside. Here is one I tried to take of the brake disk.
