Absolutely fantastic bike, their is honestly so much I like about this bike. It has gotten me through some crazy East Coast terrain, the motor is great, awesome low end and plenty of power in the mid and top. I have the stock Mikuni on with a JD red needle at 2.5 and a 35 pj and 450 main with a 5.0 slide and the GJ mods, I'm at around 800ft so low elevation, couldn't be happier with how great the bike runs. The suspension was really good straight from the start, but the forks were harsh in certain situations, put the MX tech midvalve piston and valving and the A48R cap, now the bike feels phenomenal, the shock std valving feels great, I added a low friction band, SKF seal head and race tech bladder kit throughout the times its been serviced. The bike has a lot of small modifications and upgrades to make it suit me, and I keep up with with maintenance very well. Cant wait to put a lot more time on this bike and keep figuring it out. -

**2018 KTM 300 XC** (TT is behind on their model year options) Amazing quality and performance. Best bike I've ever owned just in the short time I've had it. The engine felt a little meh with the stock Mikuni carb, but now it breathes fire with the 38mm Keihen. It's gonna be hard to go back to riding a big bore 2 stroke without a counterbalancer. When was the last time the suspension was a strong suit on a katoom?!? Let's just say I can no longer use the SSS argument to defend my Yamaha... Ktm has raised the bar and changed the game with this one! -

Bike is fantastic and rides well. Only gripe is the reeds(gappy) and the stock carb(mikuni is a pos). Other than that, its a masterpiece. No vibration, very good air forks, and super light weight make it awesome. Equip with with a Keihin carb and VF4 reeds and go ride. I got my bike as a used demo bike, it had 24 hours on it, priced at $5600, $2100 off MSRP. Got a fantastic deal! -

PWK GENERAL: PWK CARBURETORS Producing power without compromise The motocross world knows PWK. Keihin PWK carburetors is the dominant carb on the factory motocross machines. Because of their great performance they come stock on a lot of the leading brand bikes. With these features you can take advantage of Keihin's superior performance. PWK FEATURES Chromed semi-flat (D) throttle valve for excellent response and more flow at high RPM. Throttle bores sized to give maximum power. Easy jetting with jetting parts available. Quad Vents: Eliminates post jump bogging from fuel plugged vent passages PWK Air Strikers: Directs air to main nozzle for improved signal and throttle response. -
Hello, Started riding last August at the ripe old age of 28. What took me so long? I bought a KLX250, then an XCF-W 250. I love them both. What the KLX lacks in power and lightness, it makes up for in me not being afraid to work on it. I need some advice from you fellas. To optimize my carb so the bike runs as good as it possibly can without me having to shell out $900 bucks to Bill Blue. I bought the thing and it had an FMF Powercore 4 pipe on it. From what I can tell, the head pipe is stock. The carb has been modified in the following way: The washer on the needle is in the middle (3rd position). The main jet is a #132. I can tell the main jet has been changed from stock because it is not a Keihin jet. So that means the previous owner did some jetting to suit exhaust. It ran okay I guess. Kinda wimpy. Especially compared to my buddy's big bore KLX 331 Bill Blue. The mods I am doing to mine are as follows: Drilling slide to 7/64ths size hole. Removed smog stuff, capped appropriate holes. Rerouting crank case vent with 5/8ths hose, bypassing air box. Installing a snorkel from a KDX 220 (currently the airbox lid is on, no snorkel) Changing out stock head pipe to KLX300 stock head pipe. That's pretty much all I can think of for performance mods. Unless someone else can think of any I am missing??? I know most of the performance increase will be from changing the carb. My options are to do the mods, throw the carb back in as is, get new spark plugs, see if it's running lean or rich, and go from there. Or I can get a #138 main jet now and see how that works. I read somewhere Kawasaki recommends a #138 main jet to derestrict the bike (I will post the information below). Any experts can give me advice on jetting/mods? All the above mods, UNI foam air filter (red one), 300 meters (1000') above sea level. I just want the thing to perform at peak with the least amount of $ spent. Thanks guys, and awesome forum!! Here is the post about the Kawasaki recommended derestricting methods, can't remember source but from some forum: For Reference: Derestriction Procedure For Standard KLX250T9F To improve the performance of the KLX250T9F model for competition purposes, the following modifications may be performed 1) Remove the carburettor. 2) Remove the carburetor slide and Jet needle. 3) Fill the 2 holes that are beside each other towards the top of the slide with a suitable plastic or metal epoxy. Sand off any excess taking care not to remove excessive material from the slide surface. (The hole in the lower part of the slide must not be filled or blocked.) 4) Alternatively replacement slide part number 43028 – 1081 may be used, this part does not have the restriction holes and is available through the Kawasaki spare parts department. 5) Place a spacer (Part # 92022 – 1003) under the needle jet to richen it up 0.5 clip position. 6) Suggested main jet for modification of a standard bike #138 (Part # 92063-1015) 7) Suggested air mixture screw setting is 2 ¼ - 2 ½ turns out from lightly seated. 8) Remove the intake snorkel from the top of the air box. (Do not remove the air box lid) 9) Re-assemble the motorcycle and test, sometimes alteration to the carburetor mixture settings may be required to obtain maximum performance. Each motorcycle should be jetted individually, however the above settings will generally be very close to optimum. -

Hey everybody, my 250f is leaking fuel out of the overflow and I tried everything to get it to stop. The float needle seat is pressed in on my fcr flat cr carb I removed it with a slide hammer but the piece is junk. My question is, is there anywhere to get this pressed in seat?? I can't see to find one anywhere

Guys! Rebuilt the accelerator pump and still got the problem. I shot a quick vid. Can anyone see anything wrong? My mixture screw is at 2 turns if that makes any diff.

Bike has exactly two downsides. Lack of Gnarly pipe with Q availability and rider skill level.
