Outlaw 525 factory jetting issue?

[ScramblerXLE]

hey guys,
I was just told on another site that someone had heard that in order to make EPA standards, the 525 'Law was jetted too lean from the factory. If this is true, the 5 degree wether up here in MI might really make it lean next weekend when i break it in (if it comes...it should,) anyway, i've been told that guys are already rejetting theirs to compensate. Could someone tell me if they have experienced this? maybe check your plugs and tell me if they're the nice brown color that i'd expect a factory machine should be? If not, perhaps a larger main is in order. Thanks!

EDIT: title of thread changed due to uneducated people coming here and referring to rejetting as "already having to fix the Outlaw." Title changed to reflect the necessary nature of rejetting a machine which any concerned owner SHOULD do in the conditions those of us in the north are currently experiencing.

I would call a ktm shop, or go on KTMtalk.com. My 525 (motorcycle) was rejetted at the shop before I picked it up. They are real lean from the factory. I would imagine that the 2 wheeler parts should fit on that motor. The most popular is the JD jetting kit, an oring around the accelerator pump lever, the honda ac pump diaphram, and the HT racing vane velocity stack. I can't wait, I know my 525 is way more than I need.

Pretty much all bikes/quads will come out more towards the lean side for EPA purposes.

The Outlaw 525 comes stock with a 148 jet. Anything below 40 degrees the book says to go to a 158 jet. Those of us that have commented that it is lean have been riding in single digits and teen weather. Like any carbed quad. You should expect to rejet when the weather gets this cold.

I live in central WI and the temps have been -0 to maybe 10 degrees above in the afternoon. I can tell you that stock jetting is way to lean. My plug was white. I ordered the JD jet kit and installed the 172 main along with the blue needle and also the thick o-ring.

The plug is now the color that I want it. I thought the 525 was a handful stock, it is an animal with this jetting kit. The best money I have spent. It feels like 3rd gear is 2nd and so on, the increase is unbelievable.

A good place for KTM info is KTMtalk.com

I ordered the JD kit today. Does the jet kit also come with the thicker o-ring for that mod or did you pick it up elsewhere?

[groundstrike]

my kit came with 2 o-rings a thin and a thick one...

hi guys can you give some more info on this jd jet kit? thanks bill

I picked mine up at ktmcyclehutt.com #JDK002 part number. You get two needles, two o-rings and the following main jets 162-168-170-172 and also, some of the best instructions I ever seen. Money well spent!! You won't be dissappointed with this.

I just ordered my JD kit as well. I probably will not go with the 172, probably the 170, since we have warmed up into the 20's here in Ohio.... Couple questions for you:

What elevation are you at up there in Wisconsin?
What clip are you putting the needle on?
How many down from the top (blue needle right?)?

I believe we are at 1,200-1,600 around here. On the blue needle I am 3 down from the top, that is what he recomended. You may want to go to JD's website and e-mail him. A great guy to deal with and always fast answering his e-mail's
