So my yz426f runs super hot out the pipe and head when i run the bike with the choke off, but if i run it around with choke on the bike runs cooler... so should i up the main jet? i already upped the pilot. the main in it right now is a 162s? i have no idea what the s is or if thats a big jet for that bike i just got it... it has hotcams and a pipe on it. i live in pittsburgh so i live at like 1000 elevation.
