Thanks, Almond! I think you have covered most of it! I have ordered an aluminum 34T 520 rear sprocket with some kind of bronze hard coating. I also have a conical air filter and three jets on their way... 105, 110, 115. At my altitude, I am gonna start with the 110. If it is too rich, what kind of symptoms might I see?
I am changing out my tires, as well. My bike came with a 80/100 front and a 100/90 rear. I am putting on a 90/90 front (Cheng Shin Barracuda C926 from JC Whitney $29 or so) and a 120/80 rear (Metzeler ME1 from Ebay, $36 with shipping).
I also installed a trunk from JC Whitney as well. The medium-sized trunk is a great size for this bike, it and mounts with two bolts without drilling any holes. This is a great asset for riding my 6 yo! I don't have to worry about her flying off the back! It also gives her a great sense of security, and it doesn't even block the use of the handles on the sides of the luggage rack. If you are interested, go to
