I purchased a very lightly used 99 PW80 from my neighbor for my 10 year old. It is only used riding around our 1.5 acre yard so the top end is not a factor but after reading lots of mod posts it seems that dropping the front sprocket a tooth or two would help as well as the air in and out. Where can I find the correct sprocket for this bike? Airbox mods and exhaust seem to be pretty straightforward.
