My son's 2002 XR80 is in need of some additional low end torque. We replaced the air cleaner wtih a UNI filter and cut away all of the meshwork from the metal filter body. We have ordered an exhaust tip so that we can remove all of the exhaust baffle and relieve backpressure a bit. I suspect that going up a size or two on the main jet might also help. (PC20J carb). Does anyone have suggestions on main jet size increase? Also, where is a good place to purchase the jets?

We're also considering a 13T front (stock 14T).
