After like 3 fiddyless years I'm finally back

More pics once I get everything back down... as of now I can do alot of my first gear stuff (besides straight line sitdowns, I think relearning endless circles first wasn't a good idea ) but second gear is like I'm learning it for the first time. Does anyone know where to get the mixture screw adjuster? It has the stupid D shaped one. I never messed with it on my other fiddy, did they all have this one? I feel like my old 04 had a slotted screw unlike the D on this 06.

Also got to order some parts from Ryan, I'm thinking stunt pegs to replace the single BMX peg that's on the left and bigger street pegs w. sliders, extended brake pedal, bar ends, and I'm thinking of switching back to 50 Stunt handlebars cause I don't really like these Pro Tapers. Also I definitely want to get ASV's again, they are great levers. I'm also trying to decide whether I want to go with a geared Stage 1 or 2 88cc or just keep it stock, but that will be over the summer. Any opinions on Stage 1 vs Stage 2?
