Small sha and big kit mean too rich an idle when your top is right, you can mod your slide and it will help. Shave the bottom with more angle as discussed here: https://www.mopedarmy.com/forums/read.php?7,3065085,3065486. Make it more like a #4 or #12.
You're also running a stock pipe, which is gonna cut your jetting way down vs an expansion chamber. It should run ok, but I'd still get a 14mm bing in the end. I'd also get a new chain before that rusty thing whips you in the leg. Either way it's gonna be a cool looking bike with that color combo.
