Lean or Rich?
Posted March 08, 2006 - 01:26 PM
Just bought me a new 04 WR450f a few months agonn. So far I think it's the best purchase I've ever made (other than my son's pw50). I'm pretty new to the dirtbike world and after reading many many posts on here I'm wondering...how can you tell if your bike is running rich or lean?
Thanks in advance,

Short of that, if the bike bogs, it is ?????, and if it sputters, it is ???. Someone who knows will have to fill in the ???

168 main stock needle in clip #4, get a 48 pilot, zip-ty adjustable fuel screw and a 72 starter jet. replace the stock cork with an aftermarket insert like PMB or GYT-R remove the snorkel from the air box and you should be good with this jetting most of the time in Kentucky. Drop the main in the summer to a 160 if you get a lot of cutting out at open throttle.
