"son you are a lot lean your pilot should be 48 and your airscrew at 1.5 and the mainjet should be 175 if you have K&N"
Guys please help.....pretend that your telling a 10 year old how to exactly do this, except for the main jet, where is the pilot and how do you change it and where is the airscrew?? :uhoh and when you say 1.5 do you mean screw it in til it stops then back out 1.5?
think of it like this, lefty loosy right, so the screw is comming out and opening up the air flow to lean out the fuel, righty tighty so your closing the gap for the air to flow therefore making less air flow into the cylinder making it a bit richer... its almost like a choke, thats the way i see it
You know what's funny... I'm running a 45 pilot, YZF needle on the 4th clip, and a 170 main with my fuel screw at 2.5 turns out. My bike runs like a champ....A CHAMP!. Total response through out the throttle position, doesn't lean out at WOT, idles like a dream and the end of the pipe is just a med.-dark gray......perfect. Why is everyone going SO huge on jets? :what
And before ou say I'm not geting full power......I've kept up with a 250A GNC rider on his LSR CRF 450 quad, and was dead even on the starts to the first corner.....after that skill took over and I got smoked :angry but when we parked he was in shock when I said my motor was basically stock..... :eek
I hope someone can help in the process of jetting I accidently moved the slow jet flat screw(instead of air/fuel screw) does any one know where it should be stock. If someone is jetting please try and check for me......
