    I'm reading spabkeys jetting guide and I want to confirm that 1 turn on the air screw = a complete 360 degrees

    Also I was told when I bought the bike to do 40:1. But manual days 33:1 (32:1) but Im starting completely fresh jetting the bike should I start with factory recommendation and stick with it. 02 husky wr 125 I live in Massachusetts and I'm 190 lbs (gear on). Thank you

    Many. Too many.
    1 turn = 360 deg. If you rev it hard most of the time, use 32:1. If you are woods riding and in-and-out of the powerband, spending pleanty of time with the powervalve closed, use 40:1.

    What oil are you using? I'm using 50:1 amsoil interceptor,just did the top end after 4 years and it looked new.Synthetic oils today are really good.Cant help you with jetting.I'm at 6,000'

    Might be an OK starting point but you might also get more performance and MPG by tuning it to your bikes needs and your riding style. Read up on what the circuits do and then ride the bike and decide if you feel it is running right throughout the range. If not make a educated guess based on the different circuits what needs changed and change one thing at a time so to see the effect. You can always go back.

    I use motorex low smoke pre mix I was considering going torco or ams. I also do a lot of trail riding not using the bikes full power. The reason I'm looking into jetting is I do get the spooge out of the pipe. Yes it's new top end an re packed muffler. Is the 32:1 ratio more for a high rev engine and 40:1/50:1 more for a trail bike. I also read just cause the ratio say for example 40:1 has less oil in the mix. It actually makes the mix richer in the carb? Does that sound right?

    I'll repeat it again, NOTHING AT ALL WRONG WITH SPOOGE FROM THE MUFFLER. Simply means your oil is lubricating the motor. Read the plug and jet according to that regardless of spooge.

    yes, it is all about ratios. More oil per gallon = less gas per gallon and leaner air/fuel. Less oil means more fuel per gallon and richer air/fuel. Although you could run anywhere from 30:1-50:1 on many oils and not see much of a difference running wise. Somewhere around 40:1 on modern oils seems the norm these days.

    If you are trail riding and not on the pipe constantly 40:1 is a good bet. After that dialing in the jetting, especially the pilot jet will clean up much of the spooge. A little is fine, but if you have a lot it's usually too rich.

    I've never heard a theory that spooge dripping from the can is normal or good. Our 125s are run pretty much wide open and the only time we've had any was on my bike when I didn't realize the air screw was closed. 44:1 on everything and no abnormal wear or ring/piston life and no spooge.

    I appreciate your insight (YOGI). :D Just kidding.
    How has the spooge been on your 04 165 been? I remember you saying that right after putting the Lectron on, it went away even on the gnarly nasty stuff you ride?
    Just curious?

    i ride bottom and mid 90% of the time. Also lots of very long steep downhills where you off the gas and at steep angles for long periods of time.

    I think the amount of sponge coming out of my exhaust would relate a jetting problem. Going to set the jets all back to stock owners manual try 40:1 due to my riding condition and see how it is. If I put my hand at the muffler end it will have oil spitting onto it. I agree spooge let's me know everything's lubed. But I just don't think this is right.

    Yeah, I guess that goes for 90% of the 125-167 riders here. Hard to wrap my head around that still.

    Going back to stock is a good place to start. Then, like you said use Spank's jetting guide to set you up. Pilot jet first, then needle, then main jet.

    That is awesome! The trails around here are disappearing:( I've been hitting MX tracks mostly this year...

    Yeah, where we ride it's 9k RPM, fan the clutch, 3 gears up, 2 down, 2 up, 3 down, clutch pop before every jump if you stay in second. :eek: Different terrain. NJ sand scrambles or MX is totally different than where you guys ride. I can't stay under 5k for anything over here.
