Got the new sprocket installed today.
It added an extra 5 mph with the carb running really bad. The carb is running rich and so it four strokes at WOT. Before the gear swap this would have limited me to ~18 mph. Today I was able to cruise at 22-23. I'll probably just cut back the fuel shutoff to run correctly at WOT since messing with the main jet is a PITA and a huge gamble for it to turn out correctly.
Then my rear tire tube blew out so I'll be swapping both tire and tube tomorrow. There is something wrong with the tire because this is the third tube to blow out.
