Hey Nystie, how did they do the jetting, on a Dyno or by the seat of the pants and plug chops?

Hey guys, just bought the new outlaw and it absolutely rips in this 30 degree weather out here in Pa... i havent rejetted it yet but it runs great! Where do i buy this jet kit and which kit is it? i checked jdjetting.com but i wasnt sure which one has the right jets. are there any pipes, or other mods available at this time? Is there anythig to be gained by removing the spark arrestor and intake box lid? Thanks for your help!

call JD Jetting @ (253)939-7114. They can set you up right.

The EHS Airbox lid should be available by wednesday for it (i'll post if it is). It is essentially just the factory airbox lid with the snorkel area cut off and a huge prefilter bolted in place. voila, the protection of a closed box with the flow of an open box.

Also, muzzy's has a system out, as does HMF. I am waiting on the FMF system however as that is the system that KTM uses on their factory teams. ETA is between 1&2 months, but no "official" release date yet. Again, expect a post the day i find out otherwise.

My current set up with the JD Jet kit is:
Red needle, 4th clip
170 main jet
stock pilot
Fuel screw 1-3/4 turns out
O-ring mod // YES IT WORKS! YES THE GAIN IS SUBSTANCIAL!

Good luck let me know if i can be more help!

hey guys I just got back from the dunes and my 525 kept runnig hot and lean. I was just curious if anyone had any jetting suggestions. I'm at 1000 ft up 87.5 (85 stock) pilot 152 (148 stock) main needle in stock position. stock air filter and pipe.

Buy yourself a JD Jet kit and try the recommendations in the kit. They will get you very close and will be a nice gain in power over the stock setup. It is worth every penny that the jet kit costs!

As lean as these 525's are at a 148 stock jet I do not think a 152 is nearly enough of a jump. If you look two post above yours I am running almost the exact same as Walt, except I am on the 5th position down on the red needle. I am running with no lid on my box, but those that have been running with the lid are around a 162-165 range on the main jet.

The one time I ran with the air temperature in the 80's I was a little rich, not bad though. I am going to wait till I get an exhaust on it before I mess with the jetting again though because it runs awesome with the temps in the 50 to 70 degree range.

I don't know what temp it was, but even the service manual for temps below 40 , they recomend a 158mj which is quite abit bigger then stock. So I would jump it up a bit more, or like the others said, get the JD and they will tell you what's best.

thanks everyone! I think I'm going to jet up to a 160 until my JD kit arrives.
