Been a while Chris. Is this a good kit for my ‘81? I know the description says it is, but those things lie a lot, lol.

Our attention gets drawn away frequently. My bike is embarrassingly still sitting. It’s been more than 10 years. I’ve ordered some new bits and it’s getting worked on as soon as they get here. It’s time. Good luck with yours.
Chris, is this why they never seem to list the rebuild kit for my carb? It's always other years. They only have gaskets and float needles for 81's. I don't think the other parts will fit. I still haven't taken my carbs apart, but hopefully the jets and hard parts just need cleaning. If not...
I just need to clean and rebuild. Haven't taken them apart yet, so I'm not sure what I'll need. I see so many rebuild kits look like junk though. If you know a good source, please let me know.
Nobody knows anything about these? I'm surprised because not a lot of places have parts for our bikes. Usually, its members here who push the companies to make things. I might end up being the guinea pig on this one.
Has anyone ever used these, or heard anything about them?

Did you change everything all at once? Hard to narrow it down. Maybe put it back to stock and make sure it runs well, then make changes one at a time. When things get bad that’s your culprit.
