Hey there welcome. For starters you have a blue 83 110, no such thing as a Xmas special on the 110’s. It’s just a color option they offered. As far a mod’s go it really depends on how deep your pockets are. Honestly a pipe, cam, and a 2-4mm oversized piston will be a huge improvement and not break the bank, but even at that you will have 3-500 into it. Might be some 110 pistons on eBay or maybe someone here has one. Oh yeah get rid of that junk carb and invest in a mikuni 22 mm carb (make sure it’s genuine).
Maybe start with a cam and a different rear axel first to see what you think before getting to deep into it. If you are short track racing I would go with a bigger rear sprocket myself to get you out of the hole quick.
One more thing if you are racing get yourself some wheel spacers to widen the axel, that will give you an edge keeping it planted.
