So I've fixed my previously discussed vacuum leak, but while I had the bike completely apart, I noticed two things:
1. There is an oil leak on the stator side, coming right out from where I know on scooters and mopeds to be the alternator/stator. It looks like the stator grommet is leaking. I have not found any pictorials for this. If someone has one somewhere, can you link me to it? I could not find via forum search and the pictures in the Honda service manual are not very clear. If one has not been made, I will be glad to take pictures next weekend when I do this after the Hondabond HT and some more degreaser arrive.
2. There was a rusty pencil eraser head-sized hole in the frame, about an inch from where it meets itself at a weld. I used a welder and 3/16 in steel for the weld and sealed tight over that entire area with a 3" piece of it, almost wrapped around the frame bar with it. There did not seem to be any other aberrations or rust on the frame, so I think I'm good with that. Does anyone foresee this being an issue in the future? I did automotive welding in high school, so this isn't my first rodeo with frame repair, but I've never had to do it on a motorcycle frame- it looks like this may have been from when the bike was laid down, judging by the damage.
The bike runs an insane amount better after replacing the throttle body, I took it to the mountains yesterday after it just sitting for the last two weeks, and it took my gf and I all over the Idaho Springs/Genesee Park region with no performance issues. Thanks for everyone that helped with that project!
