Outlaw 525 Jetting poll

[ojcool]

If you have this bike and have jetted it would you be so kind as to post up your mods, jets, needle settings, pilot, slow screw settings and elevation? I'm just trying to get a feel where everyone else is since I'm pretty much starting from scratch now.

Please use the following format:

Exhaust- Stock with baffles removed
Airbox- Modified lid with Unifilter
Any other modifications that would affect jetting

Elevation- 187'
Main Jet- 160
Pilot- Stock (45?)
Airscrew- 2 turns out



Did I read that people are having problems with the Pro Motion aftermarket airscrews? Cause I have one. What exactly is the problem?


Best Regards,
Stu

would you please define "plug in the leak jet" I'm not familiar with that term. Thanks.

And you guys are mentioning two different values for the pilot jet can you explain how that works. I'm used to a Banshee where the pilot is just the pilot jet.

At 187' I'm thinking I'll go back to the 170 main, originally when I had that in everyone was saying I was way too rich, now it seems allot of guys are settling on the 165+ range of main jets.

I have the JD jetting kit if that matters. I'm running the red needle right now, should I go back to the blue needle? It's still a little cold but usually the weather is 65-80 degrees in spring summer around good old Virginia.

Thanks for the input!

Exhaust- Stock w/baffle (for now)
Air box-Lid on, K&N filter
JD 162 main jet
JD Blue needle 3rd clip
JD Big O-ring (increases accel pump speed)
JD Accel pump diaphragm (reduces accel pump volume)
Air screw 2 turns out

[bossman525]

stock exhaust baffle in
ehs racing lid with k&n filter
jd jet kit
165 main jet
red needle at 4th clip position (i just took out my blue needle, temp's have been in low 60's here)

The Outlaw comes with the Leak jet plugged. Some machines with the FCR carb like the YFZ and KTM have a leak jet that lets some fuel back into the carb instead of being pumped into the carb by the accelerator pump. A leak jet will shorten the time and amount of fuel sprayed by the AC pump when opening up the throttle.

The 2 pilots bill mentioned are the main pilot jet (48) and the slow air pilot jet (80). The slow air pilot jet can be accessed through the throttle body on the intake side.

Evasiveone, I'm curious too, you and bill are now running blue needles. Is this just for the winter, or did your exhaust mods require enough extra fuel to need the blue needle, even in the summer? I just seem to remember everyone running red in the summer. Thanks in advance for your reply.

Ok, so the leak jet is just an adjustable bleed that lets the fuel in the accelerator pump slowly empty out an back into the fuel bowl? I assume it's adjustable or is it either open or plugged?
So if there are essentially two pilot jets I assume the primary one (48) affects the idle and lower rpms and the slow air jet (80) affects the a/f before the needle becomes more involved? Does the air screw affect both the (48) and the (80) or just one? Is one considered to be leaner than the other with the factory setup?
