Default Jetting, FMF Q4 and more

Alrighty folks, need assistance on setting my 2012 KLX 250s up.

I want to keep it as quiet as I can, while still improving performance, all while not loosing a lot of MPGs.

I explore a lot of forest/gravel and back roads, do a bit of camping, photography and chase geocaches. I will be doing some off road, but nothing very technical, and all of this at what some of you would consider a snails pace I'm out to explore, relax and enjoy. I will be avoiding freeways or anything over 60 as much as I can. I may need to hit some 60 MPH roads, but I'll be off them as soon as I can.

Haven't done much but ride so far. I did upgrade to Seat Concepts seat, have the suspension improved/set to me, and I've ordered the IMS 3g tank.

Now before you all get on the "do the 351" wagon, that will happen, just not this year. I want to put some miles on her this year, and do the 351 next winter.

For now I think I want to add the Q4, KDX Snorkel, and re-jet. I've asked a couple folks in PM's about some of this, but thought I'd bring it out here for all to have some input.

What will give me the most improvement without loosing my 60ish MPG?

Seems many feel just upgrading the jets can smooth things out, I'll be doing that. While I have the carb out for re-jetting, I'll drill out the starter jet, since many find that really helps the cold starts. I live in a cool wet area and will be riding between sea level and 3500' the most (I live at 600'), with stretches up to 6000'. Adding the fuel screw for times when I may need to tweak things, to just through, anything higher (should I ever visit Colorado).

Q4 slip on only or add the pipe too?

Change the air filter? If so which one? I may ride some dusty areas, but that will not be my main riding local. Maybe 3 or 4 trips over to eastern Washington and Oregon to explore some of the ghost towns and scenic dirt roads. May give parts of the WBRDRa try, we will see if I gain enough skill for that, I don't bounce like I once did

I will be adding a rack to carry camping gear, and maybe a rotopak for some added range and security. I ride solo a good bit, so I don't fancy getting stranded just past the middle of no where.

Let the virtual farkling begin, what would you do if these were your goals?

Thanks for any input,
Cindy

Try 13t front. Cheapest and it may be all you might need.

Well, when you do the tank, rip off all the smog crap.
If you are going into the airbox, replace the filter with a good reusable.
Maybe get one of the new racks that just got made for MikeW's (I think) KLX and add a rotopax. The side coverage would be good for crashes and saving soft bags from the pipe.
For quiet, I finally found a $35 KLX300 pipe to go with the 300 header, that I got with a PowercoreIV(way loud, still trying to get the correct insert piece to quiet it down).
A skid plate is a must, IMO. It's cheap insurance against a busted case from rocks. Radiator guards are also cheap insurance against a busted radiator, they provide a stout frame around a not so stout part.
And while I'm on a protect the bike soap box...handguards will protect your levers, control pods, and hands from damage. I've had to relocate mine after a crash, but they have always saved me and the bike from ride ending damage.
Most of my "farkling" was to protect the bike from damage that I unintentionally inflict on it. So far so good.
Pogiboy makes a good point, a 13t front sprocket will make it more peppy for as little as $8 + shipping. I just went from 14/47 back to 14/42 and the bike feels like it is struggling to pull 6th (and often is). I had the 13 and 14 in my hands when I was changing the original, I got suckered by how pretty the $20 14t Renthal sprocket was compared to my $8 no name. I'm going to swap them out. It will give me the equivalent of 14/45, which should pull 6th a little better. Oh yeah, I consistently got 60+mpg revving the crap out of the bike with a 14/47.
Most of all, ride that sucker and enjoy it.

Ahhh, yup, forgot to mention I have hand guards too. Ordered a mount for my GPS, and a Wolfman Enduro tank bag.

Sounds like a rack, some bags, tools, spare parts and a direction are all I need really. The 3 gallon tank should allow me to travel 150 miles fairly safely.

I'm asking the same questions. What is your opinion of the Seat Concepts seat?

I was thinking yesterday after 90 minutes of riding how nice it is to have a Seat Concepts saddle. The best $170 you can spend on your a$$.
