i have an xr100 that seems to be running a little rich at 1/2 to full throttle. the plug seems to be carbon fouled. i live at 6200' and the temp is 60-80 degrees. the main jet currently is a 90 and the clip is one from the top. the motor and exhaust is stock. the stock air box and snorkel is gone, in it's place is an uni air filter. any ideas or suggestions on the jetting. thanks for any input.
