I have a friend who has a '06 TRX 450 and he says he can't get it to idle properly. The quad is completely stock and keep in mind he's not mechanically inclined. From his description, it almost sounds like the bike is too lean as he says it will idle fine with the choke on. Sounds to me like either the pilot circuit is clogged or it needs the next size jet. I haven't worked on one of these so I was hoping to get some info from someone who has. 1.) Has anyone esle had a problem with the stock configuration being too lean or idle issues? This quad is completely stock. 2.) Does anyone know what the stock size pilot and main jets are? Thanks in advance for any help.
