Doesn't KTM give a new bike owner the manual with it for parts diagrams and basic maintenance? They have the numbers for carb jets and needle listed in a spec chart on the older books.

Stock XCRW jetting;40 pilot,180 main, needle(OBDTR) 1st from top,fuel screw 1-1/2 out.These are 2008 specs and I'm unsure if they are different for 2009.If you remove the smog crap ,you must change the pilot to the 40.The Main jet really depends on the temperature/elevation of your area.Note;these are the stock jetting specs but not what I would reccommend.I installed the JD jetting kit which consists of a 42 pilot,175 main,two different needles(I usually use the blue one) and an O-ring to wrap around the accelerator pump linkage, as well as a few other main jets.If you don't plan on buying the kit ,try this; 42 pilot,175 main raise needle 2-3 positions turn out fuel screw 1/2 - 1full turn

Just put the FMF muffler from the "Ready to Race" kit on mine and it promptly melted the turn signal and my plastic muffler guard. How did you stop this on yours? I think the FMF Q is basically same thing as what comes in the kit. I have the spark arrestor insert in it.

remove stock stuff and put on flush mount low profile LED lights with low profile plater holder. sicass and baja designs makes some nice ones.

Can I put the flush mount turn signals on the stock license plate fender? Rather not spend the money on the other fender piece but I will if I have to. How do you deal with the frame guard melting. If you don't have anything there you will fry your pants and apparently the stock plastic guard doesn't work out that well. Or maybe I had an exhaust leak where the header and the pipe meet and that's what caused it?

sorry for the thread jack... but to answer your questions...

I think you can. but remember the big floppy stock plate holder will most likely break off or get wadded up after a few good landings... you might be able to cut it down and make it low profile yourself... i just pull all my stock stuff off and kept it in one piece and bought new stuff... the new stuff was around $100 which included plate holder, LED flush mount turn signal and LED tail light.

I don't have issues with the pipe/header melting any other plastics. I do need the guard for where the header and pipe meet... I keep burning my shoes and boots there.

Ok thanks for your help. Yes that guard that I started to melt today is the one you are referring to. Without it I'm pretty sure I would melt my boots/pants.

If I understand you correctly if I change my jetting to what you posted for my 09 530 exc-r with stimulus FMF pipe I should be ok. Now that I changed pipe I have a bog if I snap throttle hard. Will I need a new leak jet or accelerator pump adjustment?

Thanks

Well,I don't know how much four stroke experience you have but any four stroke that you snap the throttle it will bog. Real world test would be to roll the throttle on in a tall gear and see how it responds.

i installed JD's kit and had great success. It has the AP mod, O-ring mod, a few different jetting configurations, and instructions on when to use what... also the phone support is great.

it solved my bogging issues. I also have the 530 excr.

if you search on this forum you'll see some other good non JD suggestions as well, and it'll probably save you a few bucks.

I think using a 48 pilot would be too big though.

It seams to me if you do the o-ring mod you have to run a leaner pilot so there for I don't o-ring it and run a larger pilot.On my 525 after I o-ringed it it had a bad bog so I keep leaning out the mixture screw to the piont it was almost shut and finally just took it off and runs great now, this should open a can of worms.:p

I'm going to search for non-JD jetting solution. Do most of the non-JD solutions leave the AP and leak jet alone? Also if I have 45 & 175 what direction do you recommend first?

Put your 45 and 175 in and run your stock needle 5th clip from top. Hope that helps.

      Looking for something a little lighter and faster to supplement my xr650l and I think this bike might fit the bill. I'm hoping there are some owners here who can give me some insight into the typical experience with this bike. The question I'm most concerned about is how many hours these engines last before needing a rebuild with normal trail riding? Also, how do they handle in technical terrain? How about on the road? 
       
      The machine I'm looking at has about 75 hours and 1,500 miles on it, all stock other than a lectron carb, and comes with some dualsport lighting not installed. The current owner's asking price seems pretty high at $4500, but he seems to be a communicative, eager seller, which is practically unheard of in Upstate NY where the vast majority of dirtbikes on Craigslist are owned (or "owned") by rednecks trying to flip them. I'm willing to pay a little more than market value for this reason.
       
      Thanks for any input!

      Hi all,
      I got a set of the Axis passenger pegs to fit my 14' 500 exc. The bike does have the alloy sub-frame, but I'm curious if anyone has used this set up with success without destroying the sub-frame or their wife/gf? 
       
      Short trips like errands and rides out to the coast for hiking. 10-15 miles on the longer rides, and likely 0 miles on the highway, as she is not super stoked about riding. But our job kinda doesn't allow multiple vehicles. Yachties. Also shopping a sumo set up at the moment too. 
       
      Thanks folks!!

      Recently,I took a trip out to Colorado for some R&R on a family vacation. I brought my riding gear and had planned on renting a bike, but I was too late and at least what I looked at, there was no availability for my timeline. Bummer, since I'd not ridden the rockies in over 4 years, something pretty special when you live in flatlanderville (Florida)! 
      But, behind the scenes, a couple of TT'ers were at work! Through TT, we recently hired a fine, young gentleman to head up our advertising sales team,( @Freemotion ) and he pulled some strings with a local who had a well equipped  KTM 450XC-W that is his back-up machine. His new love is a 2019 KTM 300 TPI and it was gorgeous!
      So, a HUGE thanks to @Freemotion for greasing the skids in getting me a skoot and to @G 9.5 for generously lending out his bike to basically a stranger. The weather was great, so was the company, and the riding was epic as far as I'm concerned. I'm still a bit humbled by the generosity, so I wanted to share a story that I bet isn't as uncommon among the riding community as one might imagine.
      Dirt bike people rock! 🤘

      Hello TT peeps. I currently have an 11' Ktm 450 exc which i am converting to sumo. Still on the fence about getting cush drive rims or standard rims. Not too much info on what cush drive does for wheelies. I know its smoother on the tranny and chain but will it make much of a difference with slower wheelies/stunting? I had a DRZ with standard rims and slower wheelies were very choppy and almost impossible to control smoothly. Any advice/tips/help will be much appreciated. 
      Also.... will 5" rims be pushing it for chain rub? Should i just stick with 4.25"?

      Hi, I was wandering if anybody has recently bought or sold a 2014 or 2015 500 exc?  I'm trying to get an idea as to what they worth presently.  Thanks for any help.
